Almost everyone who prefers to drive UAZs had to think about how to install a diesel engine under the hood of their SUVs. First of all, the installation of a diesel engine at the UAZ would make it possible to save on fuel.
For an engine on a UAZ, which is fueled with a diesel engine, less fuel consumption will be required due to the increased efficiency. In addition, the diesel engine on the UAZ will be more responsive than the one on gasoline. These are the devices that will issue more power with low revs.
It is now quite easy to make the choice of an engine for UAZ. In theory, experts can fit all sorts of powerful units under the hood of this car. Any difficulty in the process of this certainly lies in the cost and availability to install a new engine.
It is necessary to select an engine with diesel type fuel for UAZ in accordance with certain criteria. For example, it is necessary to take into account the magnitude of its torque. Engines with low rpm, such as ZMZ-402, ZMZ-406 and similar ones, may be suitable for UAZ. In the opposite case, it will be necessary to redo the gearbox and axles.
What to put on UAZ
It is recommended not to do experiments, performing the installation of an engine that has not been tested in practice, but to use the experience of specialists. For the entire period of time during which UAZs exist, they tried to install different engines including diesel. Of these, there are some that will perfectly fit this car without significant changes. So, for example, for an Oise of the "Loaf" type, an engine from a Ford can perfectly fit, and when to be more precise, then from a Siera. The gold of this unit is 2.4 liters, and their production was carried out within 1984-1990. The indisputable advantage of these engines is the state of its reliability and long-term operation. Engines made in America can last three to four times longer than those made domestically. Diesel engines from Mercedes are even more popular for installation on UAZs. Naturally, who has no desire to make a Mercedes out of their modest UAZ?
In order to make a replacement, preference is given mostly to engines running on diesel from 2 to 2.4 liters. At the same time, according to the design, engines from Mercedes, which were produced during 1980-1984, are suitable for the change. But quite often, Mercedes engines of a similar type have rather serious vulnerabilities, and certainly the presence of an oil-type filter. It is located in the engine underneath and can simply be damaged when passing difficult sections. But this is easily solved by installing additional protection.
How to install a diesel engine on a UAZ: features You can install a diesel engine on a car, as in specialized auto repair shops, or do the installation on a UAZ with your own hands. The most important thing when installing a new engine is connecting it to the gearbox. For these purposes, special adapters are needed.
When there were no difficulties with this, then further it is necessary to determine how the screwing of the engine to the car frame will take place. Here you need to contact the welders for help, because you need to digest the brackets or add new ones. In the future, you just need to connect all the engine controls, and, of course, make its settings. When the engine is with an injector, it is hardly possible without the advice of experts in the electronic business. When the engine is placed on the UAZ, the car must be re-registered with the police, there it is necessary to confirm the change of the engine. In the opposite case, the car may simply be confiscated during the stop of the Gai. How to highlight and what to put on the UAZ diesel not on their own, can result in a significant additional amount. In general, in more options it will be worth it.
Having made a change of the UAZ engine with their own hands, the owners of the UAZ may not remember that about failures, sneezes or lack of traction for low revs... Further, the car will bring joy with not very significant fuel consumption due to the higher efficiency of a foreign-made diesel engine.
The nuances of the Oise diesel Oise have always been and will remain machines that are designed to be operated by real men. They were able to get a recommendation for excellent SUVs belonging to budget class, not inferior in cross-country ability to their own kind, released abroad. Spare parts for them are not very expensive and you can simply buy them, but not everything is as simple as it might seem at first.
Even Richard Diesel argued that for the manufacture of parts for engines, it is necessary to work precisely, and in Russia the work of mechanics did not reach a high level. His thoughts turned into a kind of karma.
Not paying attention to the colossal progress of Russian designers, the final state of the product's quality remains the best. This also applies to UAZs. Without a doubt, now you can meet the old models of "tablets" and "bobiks" that have traveled more than a hundred kilometers. But technology is developing with progress, diesel engines are regularly improved and their performance is increased. Now you can see goods on the market of spare parts for cars different manufacturers and even purchase a two-cylinder diesel engine, which not so long ago was a commodity that belonged to the category of rare.
It is no secret that, as for UAZs used for commercial purposes, for budget purposes and others, whose work is carried out in harsh conditions, the maximum will be a diesel engine. It will prove to be more reliable, economical, unpretentious and more durable than those on gasoline.
Therefore, the topic of changing the engine on gasoline to diesel will not raise doubts among the majority of car lovers of this brand. Russian production... It remains only to choose and purchase a diesel-type engine on the Oise, but difficulties may begin here, because you definitely cannot know what to prefer.
The cost of new UAZ diesel engines is slightly higher than similar used engines automotive industry from Asia.
More car enthusiasts will prefer to choose Japanese manufacturers and this is understandable.
Engines produced in this country are more reliable than Russian ones. Also, due to the not very large size and the similarity of the design, they can simply be "sharpened" for the design of the UAZ. And the market offers a large number of foreign models, for every taste and color.
A car with such an engine will differ significantly from the one on which a gasoline engine is placed. Some traction of a steam locomotive and a temper that is difficult to keep will appear in it. What else is needed for hard workers from Ulyanovsk? It is clear when the car is required high speed, then you need to use a gasoline engine, and when you need an SUV that is not afraid of dirt and rough terrain, then a diesel engine will be an excellent purchase.
Advantages of Diesel Engines A diesel engine, in comparison with gasoline, will have many advantages that it owes to its ever-increasing popularity. Now, due to the fact that tools with the performance of electronic diagnostics and specially designed equipment are ubiquitous, maintenance of diesel engines in accordance with high quality received widespread access, which makes it possible to maintain diesel engines in excellent working condition for a long time without expensive overhaul. Therefore, an increasing number of car lovers prefer the diesel engine.
One of the main advantages of a diesel engine is its economy. A diesel engine has an efficiency of approximately twice that of a gasoline engine, naturally will consume less fuel. Another advantage of diesel engines is the high torque value even at low rims. This will press down the car's flexibility when driving, makes it possible to move with ease and overcome any obstacle.
Due to the presence of optimal torque in a significant range of revolutions, the engine power on a diesel engine is used with a much greater effect than the engine power on gasoline. The most widespread models In UAZ cars, and now there is no tolerable and non-diesel engine that would be able to further reveal the excellent value of the potential of the Ulyanovsk all-terrain vehicle.
In the first place is the unit on a diesel engine from Ford, and specifically the Siera model with a capacity of 2.4 liters, produced from 1984 to 1990. Another model is the Ford Scorpion, which has a volume of two and a half liters, which was produced from 1984 to 1990. For your information, engines from car models made in America are capable of serving for a long time. The two proposed diesel engines are ideally suitable for replacement with a regular one that runs on gasoline and has a loaf of UAZ. It will not be difficult to adjust these engines, as for specialists who have great experience, and for people from the people.
Another brand of cars that could find wide distribution in the UAZ Bukhanka is a diesel from Mercedes. Powerful units with a volume of 2 and 2.4 liters, which were produced from 1980 to 1984. The plant producing motors, and being part of the Sollers concern, began to supply car factory Ulyanovsk, the first engine on a diesel ZMZ-51432 "Euro-4" in order to work out the technology of assembling the machine on the stream, the press service of RIA reported. Oise with a diesel engine ZMZ-51432 (2.2 liters).
A small volume engine belonging to the new generation ZMZ-51432 (2.2 liters) with a fuel supply system " Common rail»Was able to undergo qualification experiments in order to confirm the declared characteristics.
What machines will they be installed on? This engine will be produced in various designs to complete the entire line of UAZ vehicles for the transportation of passengers and cargo. Diesel engines ZMZ-514 "Euro-3" produced now on the territory of the plant are supplied to the complete set of "UAZ-Hunter" and the so-called "loaf".
The latest developments in the Euro-4 diesel engine; used more than a hundred parts and assemblies in the original design.
What is typical for a diesel engine?
The optimum engine power value has been increased from ninety-seven horses at four thousand rpm to one hundred and fourteen horses. At three and a half thousand revolutions, the magnitude of the torque is from twenty three kilograms of forces at 1.8 thousand revolutions within a minute to twenty seven kilograms of forces per meter. The plant produces more than eighty engines with different modifications with a volume for work from 2.2 liters to 4.67 liters, which meet the environmental standards of modern times, for cars with buses of three Russian companies - OJSC "Uaz", OJSC "Pavlovsky bus" and OJSC "GAZ".
A petrol-powered UAZ versus a diesel-powered supercar. A car from the Volga region with sixteen valves can pull more quickly, and its working interval is wider. Therefore, the "steps" between the gears are not so felt. But any switching again forces one to recall the Arzamas specialists, and the development of the pace during acceleration without hope can be lost by making convulsive attempts when placing the necessary stage in the bowels of a harmful box.
In addition, the Oise is an infrequent option when the lack of dynamic properties is only beneficial. After eighty kilometers per hour, Hunter will be in a "floating state" on the surface of the road, in need of constant leveling, and even on not very large irregularities he will jump in different directions. The car absolutely does not recognize insignificant deviations of the steering wheel, and in response to turns of the steering wheel, which have a deep roll, it will shy away to the side. This will not only turn out to be not entirely pleasant, but it will also become dangerous. So before the skid is close, and overturning will occur.
The UAZ Patriot diesel sample was able to generate a lot of interest. In general, the main advantage of a diesel engine is traditionally considered to be the traction of a steam locomotive at low speeds and not high consumption fuel.
For drivers who are accustomed to driving a petrol-fueled engine, the sensations are not quite ordinary. They give the impression of a car with better dynamics. However, can this affect the state of the driving quality? In reality, no.
In general, motorists need the amount of torque on the wheels from the car, and what number of revolutions the engine makes does not matter (in addition to the emotional state of the driver).
There is only a condition: the correct choice of transmission gear numbers. In addition, diesel engines have a poorer adaptation coefficient than gasoline engines.
It is not worth describing this concept in detail, you can only add that for drivers this will mean more often feasible gear changes (when the gearbox has a device with a manual mechanism). Similarly, diesel engines, as usual, have worse mass indicators of dimensions. For example, the power of the Iveco diesel engine is lower than that of the ZMZ-409, but at the same time it is heavier. There is a rather significant negative point: any diesel engine with a "Common rail" power system will make more noise than gasoline engines. Every gasoline engine will crackle. The fact that diesel engines will consume less fuel is not to be disputed. However, will they spend less finance? Not every time. You can calculate the difference in the price of one kilometer of road for a UAZ Patriot with an Iveco diesel engine and a gasoline engine.
A patriot on a diesel engine will consume ten liters of fuel within the city limits at nineteen rubles and fifty kopecks per liter. That is, 1.95 rubles per kilometer. The one on gasoline - thirteen liters at twenty-two rubles. The result is 2.86 rubles per kilometer. This means that the diesel engine will save ninety-one kopecks per kilometer on fuel. Quite tangible savings.
Conclusion - there are many advantages of UAZ diesel, there are also disadvantages, to choose each motorist at his own discretion!
The following engines are installed on UAZ-3160 vehicles:
- UAZ-3160 - gasoline, in-line, four-cylinder, with fuel injection, model UMZ-420;
- UAZ-31601 - gasoline, in-line, four-cylinder, carburetor, model UMZ-421;
- UAZ-31602 - petrol, in-line, four-cylinder, with fuel injection, 2.7 liters, model ZMZ-409;
- UAZ-31603 - diesel, in-line, four-cylinder, model XUDI1ATE / L by "Peugeot," France;
- UAZ-31604 - diesel, in-line, four-cylinder, model 425LTRU from VM, Italy;
- UAZ-31605 - gasoline, in-line, four-cylinder, with fuel injection, model UMZ-4213.
Engines 2.4 liters are produced in two types - with a new pump (type GAZ 2410, "separate" from the thermostat), a new thermostat, a head under the power steering, a new block (with a rear oil seal from the "eight") and the second - "old" design. ("Three-liter" - only "new".) When looking at the engine, it can be seen as follows: in the new version, the lower radiator hose goes to the tee, and from it one end to the pump, the other to the thermostat. In the old one - there is no tee, the hose goes to the pump.
The main differences between the "three-liter" engine and the "native" 2.4-liter:
- volume increased to 2.89 liters by increasing the piston diameter from 92 to 100 mm;
- lack of sleeves. Controversial issue. Factory engineers say that this was done to INCREASE the engine resource, since the block processing technology has been changed and the wear is now less. The main part of the population believes that this is bad and only DECREASES the resource;
- the appearance of a rubber crankshaft oil seal (instead of a "lace" padding);
- the cooling fan does not work constantly, but through a viscous coupling (more often the engine is NOT equipped with a viscous coupling);
- another thermostat (higher response temperature).
Outcome:
power - 86 liters. with. instead of 78 (see also);
torque - 19.7 kgf * m instead of 16.8.
The block is aluminum, the dimensions are the same as 2.4. The sleeves are embedded in the block (i.e. not replaceable). Rings - 130th ZIL. The head (new sample with a tide on the side under the power steering) is identical to 2.4 liters (different in code, no differences are visible to the eye). The head gasket is different. The crankshaft is different, the camshaft is normal. The flywheel is different, the clutch housing is normal. A pump of the GAZ 2410 type - supplies coolant to the block, and takes it out of the head (earlier by 2.4 there was a head - a block - a head). The thermostat is 3-way (Volgovsky), the thermostat case is original. The piston seems to be original, with pins of increased thickness. Extra long connecting rods. Carb 151E. [Chief, Mikhalych]
I want to tell you about my feelings: a loaf (operation constantly - Moscow region, tours - from Astrakhan to Karelia) - 6 years and 325 thousand mileage = 3 times replacement of the ring + connecting rod bearings, 1 time of the piston (cracks on the skirt - low-quality gasoline ). Semi-synthetic oil. Oil does not eat, compression is normal. SUPER. And by the way VISKOMUFT - WILD HORROR and CURSES OF THE RUSSIAN PRODUCER (I tried it 3 times). [Jan Shwanskoy]
HIDDEN 2.5 - RELIABLE. I have a 402nd head on a 2.5-liter block with an 08-gland, that is, without packing. If you do not set super tasks in terms of speed and reception, but focus on RELIABILITY, then, in my opinion, a better motor than with a 21st (451) head - 75 hp. with., and it is difficult to come up with, especially with the modern quality of spare parts and the quality of roads in the outback. This is my personal opinion based on 15 years of experience with similar motors.
Yes, 2.5 is easier to repair, but it is very rare that after 40 thousand, 2.9 were covered. In my opinion, for 469 2.5 is just right, but for 452 it is better than 2.9. I have 22069-03, I carried 1.5-2.0 tons of cargo, and so, the difference in power gives an increase of more than 20 km / h with such a load. Do not scold me, I agree that it is not a regular one, but that you cannot do it for the cause. And now, if there is a question about replacing the block, I will take 2.9 again.
There is a 410 engine produced by ZMZ. This is a three-liter liner engine. The piston in it is 100 mm, but in 421 it will not work without replacing the connecting rods. Pistons ZMZ d = 100 mm are higher than UMP d = 100 mm by 7 mm.
Since March 1998 the plant has started selling models with a new, more powerful and economical carburetor engine ICE 210.10 (manufactured by JSC "RIAT", Ivanovo), created on the basis of the well-known Russian motorists ZMZ 4021.10 (Zavolzhsky Motor Plant) - UAZ-31514-028. With a volume equal to the serial engine (UMZ-4178.10) (2.445 l), its main characteristics are much better:
- higher power;
- fuel consumption is reduced by 1.5 - 2 liters (based on 100 km of run);
- significantly higher maximum speed;
- improved overclocking characteristics;
- increased engine life before overhaul;
- better engine assembly.
Weekends ICE characteristics 210.10 are close to the characteristics of another UAZ engine installed on a car - a working volume of 2.89 liters (UMZ-4218.10). [JSC UAZ]
Currently, UAZ-31514-28 vehicles with a 210.10 engine are not produced - it was an experimental model. Work on the preparation of the production of such a car is currently not being carried out, therefore, this car will not be available in the near future.
ZMZ-410 sleeve (if the designer does not lie;))), was developed especially for us (UAZ), see torque.
To be installed on a UAZ, a 4104.10 engine is needed - at least they come to our factory. At a price almost like UMZ-421.
The ZMZ-410 has its own block, a piston sleeve for 100, its own crankshaft, its disc and basket, the rest of the 402 engine.
According to the test results, the performance of these engines differed by no more than 3 percent, or within the margin of error. Both engines have the same ancestor, both engines are the top of the model tree and by default cannot differ much. All the differences in numbers are only due to the difference in methods.
Second. The ZMZ-4104.10 engine fits under the hood of the UAZ without alterations, the frame and body for these engines are absolutely the same, and if you have a three-liter UMP, then the ZMZ-4104.10 will stand up like a native. At the moment, from the point of view of the plant, these engines differ only in the QUALITY OF ASSEMBLY, well, the difference in price is about 200 rubles, which again indicates that these are two IDENTICAL engines.
Conclusions, after comparing the characteristics of the motors:
410th:
Pros - "tricky" piston, build quality is higher than UMP
Cons - flimsy block, padding, paper M filter.
421st:
Pros - Strong block, oil seal, normal M filter.
Cons - poor build quality.
In terms of the build quality - that at ZMZ and at UMP, the motors are assembled with their feet, they just wash their feet at ZMZ before assembly. Having bought our motor (at least ZMZ at least UMP), we need to disassemble it, wash it - remove sawdust, and defect. Measure the PB and its pastels, check the main and connecting rod bushings, put in synthetic-resistant oil seals and / or packing for the Merc, grind the valves, defect the rocker arm axis, balance the knee assembly - then you can put the motor on the car. In a word, I would take the UMZ-421, and I would install the "tricky" pistons myself - they are the same 100 mm.
You can distinguish where which engine is installed according to the documents (two by one)
| UMP-421 | ZMZ-410 |
|---|---|
| UAZ-31519 | UAZ-31519 2 |
| UAZ-396259 | UAZ-39625 2 |
| UAZ-33036 | UAZ-33036 2 |
| UAZ-39094 | UAZ-39094 2 |
It depends on the measurement standard - according to GOST (Russian State Standard), SAE (Society of Automotive Engineers of the USA), DIN (German Institute for Standardization) ... net power, or real (the test engine is equipped with all auxiliary units necessary for the operation of the vehicle - a generator, a muffler, a fan, etc.), and gross power, or laboratory (bench) power (the tested engine is not equipped with all auxiliary units necessary for the operation of the vehicle). The gross power is 10-20% higher than the net power.
So, for example, the 2.4 l engine mod. 417.10 guaranteed power kW (hp) at 4000 rpm, not less:
- gross according to SAE J-816b = 66.9 (91)
- according to DIN-70020 = 57.4 (78)
- according to GOST 14846-81 = 67.6 (92),
and the maximum torque N * m (kgf * m) at 2200 - 2500 rpm, not less:
- gross according to SAE J-816b = 172.6 (17.6)
- according to DIN-70020 = 164.8 (16.8)
- according to GOST 14846-81 = 171.6 (17.5).
They differ in the height of the block head: under 76 - 98 mm, under 92 - 94.5 mm, under 95 - 94 mm. From the 76th under the 92nd it is done by milling the lower plane. [Chief]
To switch from 76 to 92, you need to grind the head and put the pusher rods under 92 (they are shorter in size) and EVERYTHING. The reverse transition again, you change the barbells to longer ones and put a "Sandwich" under your head from a special spacer (it seems they are even sold) and 2 spacers.
They differ in the presence of a water distribution pipe in the head 417 (removing it, we get almost 421st head, and installing the pipe in 421st, we get 417th), and the absence of tides on the head under the power steering. There are no other significant differences.
Approval is given by NAMI or the plant itself. The requirements are simple - the implant should not differ from the standard engine by more than 20%, both in power and in weight.
The idea to install the engine from the ZIL - "Bychka" has already come, but ... There is a D-245 on the Bychka. Excellent Minsk diesel engine with a hurricane torque (~ 500 Nm). By design and characteristics (atmospheric, approx. 5 liters) - the dream of any jeep. It has only one drawback - it weighs 450 kg. If you break through (illegally, of course) its installation, then in the very first swamp the UAZ will go into a tailspin and with a steep tweak on the face will disappear into the slime ...
In the former Soviet Union, only a couple of diesel engines are produced, which theoretically could be installed on the UAZ (by weight). But they are either completely dead (installed on the VAZ-2104), or complex (turbocharged) and expensive (licensed Steyr).
We have one firm specializing in installation Nissan engines RD28 (these are 6-cylinder in-line diesel engines with a volume of 2.8 liters.) For UAZ and GAZelle. This engine was installed on Patrols (but turbocharged) until 1999, in my opinion. This motor is believed to be shit. Timing drive - rubber belt. Hydraulic compensators. Aluminum block head, prone to cracking. This firm puts them not because they are so good, but because they get these motors for free (they take them off the Laurels in the trash heap in Japan). They grind a new flywheel (the old one for a box - an automatic machine) and make an adapter plate for the UAZ gearbox.
The UAZ-315148 model is equipped with a standard diesel engine (first reviews).
I made a three-liter from ZMZ 402 for my UAZka. Sleeves from ZIL after some turning and boring work stood in block 402. The piston and connecting rods from the three-liter UMP picked up on the liners, the GB gasket also came from UMP without alterations. Moreover, he covered all this with a head from 3102 prechamber.
Overheating:
The guy who put the sleeves in the block can be seen in this case, he understood that the wall at the sleeve left in my opinion even thick, 7 millimeters, and the walls of the block remained almost the same. Only the place where the studs were machined, of course the water jacket is thin in some places, but it is compensated by the high water pressure, the pulley on the pump is smaller, the radiator is from 3102, so large and thick, but not the one that is being installed now. At an air temperature of +25 and a speed of ~ 110, the temperature is stable, more, it slowly creeps, but this is a consequence of high revolutions over 4000.

I repaired my 3-liter, UMP-4218.
Costs (September 2000):
1. Sleeves ZMZ 100 mm - 600 rubles.
2. Repair at a military plant, namely:
a) boring (removal) of old sleeves, grinding new ones, 
insert (just insert, not pressing, tension 0.02).
b) welding the combustion chambers on the head, grinding, pressing in the valve seat, lapping the valve.
c) measurement of the crankshaft (norm).
So for everything about everything 700 rubles.
About the plant: the machines are a miracle, the hard workers all fled due to chronic non-payments, they barely found a specialist for me. But the one who restored the unit said that now you can change the liner itself without any problems, but it is better to sharpen the size from ZILovskie (?).
3. A set of pistons - 400 rubles.
4. A set of rings (or rather not a set (there was one lower compression ring, but there was an extra upper one (the difference was in chrome plating), there was no oil scraper kit for one piston)) - 100 rubles.
...
Total - about 2,000 rubles. I think I got off cheap. The plans were already to buy a new engine, while they were looking for a specialist at the plant.
The three of us collected and set them up for two days, five hours each. There was a big problem with the bearing input shaft, which was on the crankshaft. We decided to replace it. The two suffered an hour and a half. Removal problem (no puller). It was not possible to split in the shaft, they heated the shaft with a soldering lamp, slightly shifted the bearing holder outward by 1.5 mm, then split it. They broke one lower compression one, replaced it with a used one. In the process of strapping the engine on the machine, one of the pins between the flywheel housing and the gearbox was ripped off. Replaced in places with the upper left, tighten the nut there is still a problem. And in our places, no one installs it after the first repair.
In order to insert the piston assembly into the cylinder block, it is desirable to have a mandrel with which the rings are pressed in order to avoid their breakage. If there is no mandrel, but buying it is a problem (well, there is a toad, or there is no time, the store is far away, etc.), then this method is proposed, which is simple to disgrace and quite fast.
For the manufacture of the mandrel, you need only one or two conventional clamps, which in fact will be the mandrel: 
Then the procedure is simple: insert the piston to the first ring, put on our mandrel and tighten the clamp with a screwdriver until it stops: 
Then, through an unstable spacer (I used pieces of hardboard, you can use a piece of wood, etc.), gently tap on the piston bottom until it enters the block to the depth of one ring: 
Next, remove the clamp and tap the piston until it rests against the block with the next ring, then put on the clamp again, tighten, tap, and so on for all 3 rings and for each piston. With a little skill, each piston takes 5-10 minutes.
Yes, do not forget to orient the ring locks according to the manual (120 degrees).
1) The head gasket should not be dry and hard like a roach that has hung in the attic for five years. It is better to buy a new one in a trustworthy store (I have seen a samopal many times - very bad ones). On the UAZ, the gasket seems to be asymmetrical, pay attention to the location of the hole for oil channel in the area of the 4th cylinder. And of course, all holes in the gasket must match exactly the holes in the block and the head, both in size and location. Significant deviations are observed - the gasket is left.
2) Regarding broaching, the book says that you can stretch in two steps from the center to the edges. No matter how much I had to stretch out, I could not meet in less than three steps, and it was not worth trying. The first time you pull to ~ 5-6, the second time to ~ 8.5, and the third time again to 8.5. I was not mistaken, when you stretch the edges a second time, the center will weaken again. It makes no sense to pull harder, and it is dangerous. And yet, purely from experience: the first head tightening is not after 1000 km of run, but after the first warm-up and subsequent cooling.
I had a 4 cylinder problem, had to remove the head and carry the turner. The problem was solved by making a screwdriver.
Go to the store for ZAZ-968 or Luaz, otherwise it’s just at the dump — you need THEM candle screwdrivers. Ready! In the store - better, ask. you will be tortured to turn them out of your old head. The well (candle) must be deepened with a dipping or something else from the handy mm by 3-3.5, cut M2-x1.5 No. 1, screw it in and rivet it from the side of the cam. combustion ball acc. diameter. But for this you need to remove your head. And in the TAXOPARK they will do it with a spiral insert, without removing the head, but I don't know how reliable it is.
I've tried two ways:
1. Take off the head. You cut a thread of a larger diameter. (I did everything by hand. I took conical reamers and manually carefully unwrapped it and immediately without drilling cut the threads for old candles from trucks, it seems from Zil. I did this because it was all at hand. the plane of the candle seal.) You sharpen a brass bushing with an external thread that you cut, and an internal thread from our candle, it seems, M12x1.25. You wrap the sleeve with a candle, having previously smeared the sleeve with bakelite varnish, and riveted it out from the inside very neatly but reliably. That's all. The bushing need not be smeared with glue. It is clogged with carbon deposits. Brass holds very well and the thread in it cannot be easily torn off. Perhaps, if not scraped on all cylinders at once. I did it on two and then really regretted that I didn’t do it at all. Instead of inserting the bushing, you can try to find candles from old trucks. And twist them up. But I still couldn't find thin-walled candle keys.
2. Can also be done without removing the head. But I didn't like it. In the same way, you drill and then turn the engine with a starter to throw out the shavings. You cut the threads. Again the starter. You sharpen the sleeve along the length of the candle thread. You screw the sleeve onto the candle and wrap it in the head. The disadvantage of this method: the sleeve either remains in the head or on the candle. Sometimes, when replacing a spark plug, the bushing cannot be unscrewed from the spark plug.
If you take the head off lazily (when reaming), you can do it like this:
The piston is up, then you stuff a rag there, pour it on top with lithol from a tube. At the end of the work, you pull out a rag with chips adhering to the lithol with tweezers and a hook.
An ordinary candle, after removing the contents (an electrode with insulation), is cut into four parts to the base. A cone with a thread at the end is turned into the center, in place. Next is the case for the head and hands. We squeeze the remnants of the thread by hand, bait in the remnants of the thread and, pulling the cone through the thread, restore the thread in 2-4 passes, since we rotate from the cylinder - the chips are all out. To speed up the process - "sharpened" the candle thread on a conventional lathe.
After the amount of compression drops to a certain level, say - 5.5-6.0 - the engine just starts to smoke a lot, start poorly, eat a lot of gasoline, oil, ..
The measurement process looks like this:
1. The motor is hot.
2. The battery is ok, not dead.
3. All candles - BOTTOM.
4. Manual throttle - fully extended and LOCKED in any way so that it does not slide out.
5. Compressor - in the 1st cylinder (I screw it like a candle, but there are those that are shoved into the candle hole with an elastic band). You hold it with your left hand, and with your right you close the controlled contacts of the add. starter relay.
6. You count the crankshaft revolutions by ear. Give it 10 turns and look at the device. Indications - write down.
7. Repeat again WITH THE SAME CYLINDER. Write it down. The average value is taken as true.
8. P. p. 5,6,7 repeat for the remaining cylinders.
9. Analyze the results of the experiment. The criterion of the SATISFACTORY state of the cylinder-piston group - the difference between the highest and lowest compression values for the cylinders SHOULD NOT EXCEED 1 kgf / cm2.
10. If more - TAKE ACTION.
I once used such garbage - an asbestos cord (1.5-2 mm) impregnated with silicate glue (" liquid glass I wound it several times around the pipe and pressed it against the collector without letting it dry. When heated, the glue hardens and slightly “foams”, filling all the leaks.
I replaced the muffler with a resonator from a Gazelle and, after it, a UAZ resonator. The effect exceeded expectations !!! Consumption has decreased, the engine pulls better, the sound has become slightly louder, but much more pleasant (as if it has become more powerful and solid under the hood), and even quieter at idle. The whole structure is much more compact than the original, it does not hang down absolutely ... I advise!
I put a gazelle muffler. It is longer than the original. The resonator was left old, but the improvement can be heard with the naked ear. Recommend.
I threw out the old glushak, having cut off the mounting flange (with three holes) from it. I bought a RESONATOR from a gazelle. Only when buying a resonator should you buy where there is a reception from the UAZ. When trying on from several of me, only one resonator fit. These are the parts we produce: (I calculated the angle at which the flange needs to be welded and welded to me. As a result, nothing more hangs under the bottom. And the engine has become easier to breathe ...
After repairs, look to make sure the exhaust is not touching the frame anywhere. Moreover, it can only be touched when moving. It was like that for me - everything seemed to be fine, but in motion the knee reached the frame and there was a terrible growl.
Advantages:
- it is flat - it does not cling to the bottom.
- more pleasant roar of the motor. Moreover, at first it resembled a purely racing one, and then over time it becomes quieter and quieter. Maybe the glushak "burns" ???
- It became easier for the engine to breathe.
Sequencing:
With a "new model" exhaust system
You buy a gazelkin resonator and
1. Saw off (preferably with a grinding machine, fasteners in the form of the letter C and a knob from the long end.
2. From the old resonator you saw off the flange.
3. You screw the sawn-off flange into place to the flange of the small resonator (only WITHOUT the gasket).
4. You screw into place the old "samovar" (muffler) suspension, which is refueled under the rim (the rim itself is not needed).
5. Insert the long end of the gazelka resonator into the flange and hang the resonator above the suspension, as needed.
6.Pick up by welding (gas or semiautomatic) conscience. flange and suspension connections.
7. Take off the resulting structure and boil it.
8.Put in place (do not forget about the gasket between the flanges).
Straight-through muffler to create a new exhaust system I took it from GAZ-3309 ... Both flanges are the same and are exactly the right size for our exhaust pipe. On the other hand, a slightly cut intermediate pipe from the Volga (2410 or 31029) is inserted into it ... When installing the muffler, it is important not to confuse its position - the muffler is directional. [WITH. Kirsanov "RoadHawk"]
The nuts are unscrewed from thermal shock.
What to check:
1. Gasket - that it does not cut and does not break (the gasket with "ears" breaks when expanding along the rim - I replaced the annular one).
2. Nuts (4 pcs.) Must be copper.
Pull the nuts with a tubular wrench - otherwise the edges are rounded. Pull the first nuts firmly, but both evenly. Tighten the second (locking) with all the dope.
Put on the brass locknuts.
Pops from the mixture burning out in the muffler, i.e. it has not burned out in the cylinder.
1. (faulty EPHH) If there is EPHH, then it is clear that there is simply no mixture in this mode and there are no flashes.
2. (clamped valves) Burnt valves have such an effect when, when compressed, part of the mixture is forced into the muffler and ignites from the gases of the previous cylinder.
3. (valve seat) there were pops before the valve seat crumbled.
4. If the system is with a contact distributor, then it is quite possible that the gap between the contacts has "floated". That is, it has become smaller ... But in this situation, the machine begins to take much worse from the bottom, it becomes wadded.
5. Carburetor. High level in the float chamber and, as a result, re-enriched mixture.
In fact, a leak in this place is quite often the result of a malfunction of the crankcase ventilation system. And so, with normal packing, there should be no leakage. Even on the Mercians it was like this (by the way, it is sold as spare parts and fits very well with the UAZ)
In fact, first it would be necessary to check the runout of the KV stuffing box neck. If it is less than 0.02, then it is correct, YOU CAN SIMPLY REPLACE THE PACKING, ZHELATELO - with Teflon. And if-more-attributed to the "mechanics", everything will be corrected there. And also put Teflon.
About the rear oil seal count. shaft 402nd.
In order to stop the oil flow through this oil seal and fill in the synthetics, I used the packing from MB model 210, body 126, engine 110, part number A0019971241.
To be installed in the same way as domestic stuffing. Naturally all env. parts, except for the packing itself, must be installed on the sealer. If you fill in synth., Then the rest of the parts in contact with oil must be installed on a sealant.
The stuffing box packing wraps around the top and bottom of the crankshaft. To change the upper half, you need to remove the crankshaft and, accordingly, you must first remove everything that interferes with the removal of the crankshaft. Experienced men do not remove the checkpoint, but simply move it back. The flywheel can be left on.
Experience on the Volgovskiy ZMZ-402.
Actions:
0.to the pit
1.remove the oil pan and clutch housing
2. Remove the crankshaft support.
3.Pull out the flags
4. Pull out the old packing.
5. rush, drink beer, think "blah, what have I done?"
6. go to the store, buy a new repair pad.
7. Cut one end of the latter obliquely, fasten a piece of soft steel wire into place, wrap it with thread, so that the whole structure is thinner than the packing itself.
8. Pass the wire around the crankshaft.
9. Pull the wire, turn the handwheel.
10.cut the packing to the shaft diameter
11. Having lubricated with sealant, collect everything back.
It only helps if the reason is packing wear. Suitable from, they say you can buy it somewhere. if the reason is the beating of a curved crankshaft or wear of the oil knurling will NOT HELP!
it the best way for a domestic SUV. It is worth noting that with the given engine, the car becomes passable and stable. Further in the article, we will talk about exactly how the engine is changed.
How to install on UAZ V8 (engine)
UAZ "Patriot", like other UAZs, requires additional "file processing" immediately after purchase. True, a large number of new car owners of a post-Soviet car are limited to a simple broach of all elements and the elimination of multiple "jambs" available in the factory assembly. But the most important problem with this car is the lack of the most powerful diesel engine in the line of motors. And what to change it to? A turbocharged Cummins diesel is considered an excellent option in this case.
As soon as the Iron Curtain fell, and supported foreign cars, self-taught people appeared in the Russian Federation who wanted to install an imported engine on, in general, off-road vehicles, or rather, on the UAZ V8. At that time there was not even a scent of "patriotism" at that time, since the victims of many, sometimes stupid, attempts were various UAZs.
Their engine compartments occupied various engines, moreover, not only foreign, but also from Soviet trucks and, of course, buses - UAZ with a PAZ engine or an engine from a GAZ 66 model - that was natural.
Popular motors for UAZ
The most popular were (and are still considered) diesel engines from a Japanese manufacturer - Nissan, Isuzu, Toyota. And at the first Moscow car dealerships, a variety of private manufacturers showed samples with these motors.
After some time, the number of experiments grew into quality, they created accurate, well-established copies of the V8 engines "dump" on the UAZ-469, and the company created an updated brand of an SUV. The comfortable and roomy "Patriot" was equipped (except for the domestic "gasoline") with the Italian turbocharged diesel engine Iveco. But this did not last long - the Italian engine was removed, equipping the car with the Russian diesel unit ZMZ-51432.
In our country, UAZ "Hunter" is equipped with a V8 engine
The well-known domestic automobile blogger aGademeG showed in his video a special version of the UAZ Hunter SUV with a V8 engine. It was prepared by order of familiar automotive mechanics. An 8-cylinder engine from a Japanese manufacturer was installed in this car, which has a capacity of more than 300 hp. with.
Thanks to this engine, the Russian SUV can accelerate to 100 km / h in 7 seconds. These indicators gave him the opportunity to compete even with sports cars... During the creation of the sports version of the UAZ "Hunter" old SUV, and the space of the engine was occupied by an 8-cylinder engine from the "Toyota" concern.
In the course of the improvement, automotive mechanics installed the revolving engine in the UAZ to the maximum, thereby solving problems with the clutch, gearbox and shock absorbers (since they could burst when high revs motor). And yet, all the obstacles have been resolved, and this car has left for tests near St. Petersburg. It is worth noting that along with the Toyota engine in the improved Hunter, an automatic transmission was combined, and the car itself became rear-wheel drive.
Installation instructions ZMZ V8
Attempts have been made to install a V8 on a UAZ vehicle, which seems quite acceptable to car owners. Since the motors from the 53rd or 66th gas engines or the PAZ can be installed on the UAZ. Such engines are found in conservation and simply repaired. But there are some:
- One of the main ones is fuel consumption. There are many records about the fact that it is 10-12 liters on the road.
- The next incomprehensible situation is heating. How to cool this car, at the moment there are few answers. Many motorists talk about the use of conventional copper cooling in UAZ.
What you need to do to complete the installation the V8 engine on the UAZ 469?
- Drill holes in the clutch cover.
- Remove the bells and drill holes in them for the UAZ V8.
- Next, cut the threads for the studs.
- It is advisable to cut down the front engine mounts and dock the motor with the gearbox.
- Before installing a new engine, remove the radiator and dismantle the old engine.
All motorists point out that after installing the ZMZ V8 on the UAZ, the engine works several times better than the standard one - it is more powerful, more practical and several times faster.
What does the installation of a V8 engine on the UAZ "Patriot" entail?
The well-known 53rd GAZ truck with a V8 engine (the latter has 8 cylinders) is still used at this time. This is a car with an excellent engine, which is also installed on the UAZ "Patriot". The V8 engine from the 53rd GAZ, the power of which is 115 horsepower, with a good Hm. And on top of that, it fits perfectly in place of the usual SUV unit.
To install a V8 on a UAZ "Patriot", it is necessary to replace the exhaust system, the "razdatka" and the gearbox. After the V8 engine appears, the power of the car is felt, which is able to overcome not only off-road and various obstacles, but also snow covers. With the V8 unit from the 53rd GAZ, the car is also capable of high-speed movement along the road. The reviews available about the installation on the UAZ V8 indicate that the car is capable of moving in almost any terrain.
True, with this engine (V8), the UAZ "Patriot" works a little louder, but this, in principle, should be so. In general, Russian-made engines are known for their practicality and efficiency, and therefore, having installed the described V8 unit, you can completely forget about the standard UAZ engine, since there is no need to return the standard installation.
Advantages and disadvantages of the car after installing the V8 on the UAZ
Installing the engine has both positive and negative sides. We will list them. Available advantages:
- Power, together with the rpm on the snow cover, makes the car much better able to move.
- It works a hundred times more pleasant than the standard one, while there is no vibration.
- On an asphalt surface, the machine shows great power.
There are also some downsides:
- Resonators from the 52nd GAZ are not suitable, so you should definitely install mufflers.
- Loud sound at high revs.
- The bridge could hit the pallet. But this, of course, is not fatal, and after installing the shock absorbers, it ceases to be a problem at all.
In general, the reviews of car owners who changed the engine advocate installation on the UAZ V8.
Tuning options for this car
Tuning UAZ needs to start with the technical component - the throughput of the car will depend on this. A three-liter engine is available. This unit does an excellent job with all the duties, it does not need to be forced. It is also advisable to equip the motor iridium candles- they make it work better. And for more effect, you can bore the cylinders. Be sure to pay attention to how the unit is powered, and also to the ventilation of the cylinders.
The fact is that ventilation greatly affects the performance of the motor. To set it up, you should put a snorkel, which is displayed on the roof of the car, in case of overcoming a ford. In frequent cases, a standard motor is injected, after which the power reaches 130 liters. with.
You also need to redo the transmission - install a low main pair. This moment will slightly increase its capabilities. In addition, it is worth doing a body lift by installing large wheels. As a result, after tuning, the UAZ with a V8 engine will look just amazing.
Once again about UAZ "Patriot"
It should be noted that at the moment in the line of Patriot engines there is a naturally aspirated gasoline engine ZMZ 409.10, the volume of which is 2.7 liters, and the power reaches 135 horsepower. This is at 4,600 rpm. In this case, the peak torque is estimated at 217 Newtons per meter at 3,900 rpm. The same engine is installed on the UAZ "Hunter". On it, it is not bad at all, but for a heavy Patriot, there is definitely not enough traction at low revs.
The next option is a diesel engine with the lowest thrust here is somewhat better. On bad roads and snow cover, the Patriot with this diesel engine somehow moves at the 1st reduced speed, and if you put large wheels and a bunch of different elements, it practically loses the ability to move normally off-road.
What needs to be done and where to stop
There is no comprehensive answer to this question. But it should be noted that in the Moscow region they still found the answer - they put the Patriot in the engine compartment chinese motor Cummins ISF 2.8 l. This is a turbocharged diesel engine with a good volume of 2.8 liters (though not very powerful - only 120.6 liters. From. At 3,200 rpm), but it has an excellent torque peak of 295 Nm, which is available compared to the ZMZ diesel engine from 1 600-2,700 rpm.
A motor that copes well with the heavy "Sable", from which the four-wheel drive asked to be installed on the UAZ.
A good advantage of the Cummins ISF 2.8 liters. it is believed that it is quite common. In addition to "Sobols", it is installed on gazelles and gazelles, and, moreover, it can be without all-wheel drive... The advantage is also considered the inexpensive cost of the new engine, the availability of spare parts from domestic dealers and, of course, the ability to make repairs.
The next thing: the diesel units from Japan, usual for "dumping" UAZs, are aging, motorists have already finished off a large number of the simplest and unkillable engines from Japan, and customs control does not allow the import of cars and engines.
Existing installation problems and solutions
The biggest problem with installing the Cummins ISF 2.8L. on UAZ "Patriot" - a very deep oil sump compared to standard engines this motor... During long travels, the Cummins suspension bumps the pallet against the front axle beam. To prevent this from happening, the engine was placed on high pillows. In general, the developers managed to install this motor almost without much difficulty.
Well, a few words in conclusion
Assembling the “right” diesel unit is only part of this project. UAZ Patriot, as the developers conceived, had to become an all-round SUV, which is perfectly adapted to various operating conditions - from the track to snow cover, as well as swampy terrain. Without a good increase in wheel size, this cannot be done, and therefore the suspension was modified to be able to fit tires at thirty-five inches.
To do this, to the "lift" of the body, the suspension was also "lifted" by placing rear axle Patriot from springs to shock absorbers, as well as replacing the rear drum brakes with disc brakes.
Well, in the process, a very good all-terrain vehicle-off-road vehicle turned out. As for the improvements, here the craftsmen have worked wonderfully well, and as a result, we see a UAZ "Patriot", which is quite comfortable in many respects, which has just been fine-tuned.
What happened in the end, you can find out from this article and see the photos.
Some motorists use a Nissan engine. If, of course, finances allow, you can put on the UAZ "Patriot" and more powerful motor... The power of this unit is about 150 horsepower - this fact is considered quite acceptable. This is a diesel engine, it is also installed for installation with electronic control... But with manual control, the power becomes less - only 135 hp. with.
After changing the standard engine from Nissan, the domestic Patriot receives the following features:
- The power increases slightly. Now Russian car it is capable of getting out of any incident itself, and pulling out the same.
- Fuel consumption becomes higher due to the increase in the power of the unit.
UAZ Patriot engine, which was installed on the model of last year, remained on the restyled UAZ Patriot 2015. There have been no major changes, customers are offered a choice of gasoline and diesel versions of the engine. Both engines are ZMZ. The diesel engine ZMZ-51432.10 CRS with a Common Rail fuel supply system and a turbine complies with Euro-4. The new gasoline ZMZ-409 also complies with Euro-4 and is ready to digest AI-92 fuel. Today we will tell you in detail about the characteristics of both motors.
So, gasoline engine UAZ Patriot ZMZ-409, it is a 4-cylinder, 16-valve, in-line, with an integrated microprocessor-based fuel injection control system. Injection injection fuel flows into the intake pipe. Ignition system with coils that supply current to the spark plugs screwed vertically in the center of the combustion chambers. There are even special wells in the cylinder head cover for this. Microprocessor system with electronic unit engine control, automatically controls the ignition timing.
The cylinder block of the power unit is cast from a cast iron alloy, the cylinder head is aluminum, with two camshafts and hydraulic valve lifters. Timing chain drive... At the same time, the chain device of the gas distribution mechanism of the UAZ Patriot engine is very complex, since it consists of two chains connected through intermediate shaft... Plus there are two chain tensioners with sprockets. This whole design is the weak point of the entire engine, since insufficient tension, breakdown of the hydraulic tensioner, leads to increased noise of the UAZ Patriot engine. In addition, hydraulic lifters often fail, which leads to a knock in the valve mechanism.
Engine UAZ Patriot 2.7 petrol (128 hp) characteristics, fuel consumption, dynamics

- Fuel consumption on the highway - 11.5 liters
Naturally, the manufacturer does not name objective data on the fuel consumption of the gasoline Patriot in urban conditions. The reason is clear, a fairly high fuel consumption can frighten off buyers. If you want to save on fuel, then buy a UAZ Patriot with a diesel engine, which we will talk about further.
Diesel UAZ Patriot collected on the same Zavolzhsky motor plant... Inline 4-cylinder, 16-valve power unit with two camshafts. Timing chain drive with hydraulic tensioners. The valve mechanism has hydraulic lifters. The cylinder block is cast iron, the block head is aluminum, there is a turbocharger. The diesel engine ZMZ-51432.10 CRS with a Common Rail fuel supply system has an electronically controlled BOSCH fuel supply system with maximum pressure injection 1450 bar. To drive the injection pump (fuel pump high pressure), water pump and generator uses a poly V-belt with an automatic tensioning mechanism.
Diesel engine UAZ Patriot, with direct fuel injection, turbocharging and charge air cooling complies with ecological class Euro 4. This engine is distinguished by good torque, which is indispensable for off-road conditions, plus quite moderate fuel consumption. Below detailed specifications diesel engine Patriot.

The Patriot diesel unit has a problem with the 5-speed mechanical box gear that does not allow you to use all the advantages of the motor. When driving on the highway, the diesel engine simply lacks the 6th gear. Although it is ideal for off-road conditions. By the way, the gearbox for the gasoline engine has a gear ratio main pair 4.11, for a diesel engine 4.625. When purchasing, it is recommended to install preheater, otherwise problems with starting this engine will begin in winter.
24.04.2017
Cargo model 3303 from the Ulyanovsk Automobile Plant is one of a series of all-wheel drive utility vehicles, which also includes a van, a minibus, a medical car and a car-type model (Farmer).
The model, popularly nicknamed "Loaf", has been traveling across the Russian expanses for more than half a century, and under the hood it has evolved GAZ-21 engines. Some modifications power units are now being put on the UAZ Hunter and Patriot.
Engine UMZ 417/4175/4178 2.45 l
The next step in improving the GAZ-21 engine was the UMZ 417 engine with a compression ratio increased to 7, a modified camshaft, new 47-mm intake valves, with old exhaust valves. Also, UMP 417 received a carburetor for two chambers and a new air filter. Later, these engines began to use a crankshaft without packing.
If we compare the UMP 417 with the ZMZ 402, then their differences will be cosmetic: there are no stiffening ribs on the 417s, the liners are softer, and the flywheel has a larger size, while the principle of the cooling system is inverted.
Other intake manifold and smaller exhaust valves are reflected in the power of the motor.
Engine malfunctions are completely similar to the disadvantages of ZMZ 402, that is, they are present extraneous noise and knocking, the need to adjust the valves every 10 thousand kilometers, overheating and so on.
Vibrations and jerks occur due to the curve of the design, resulting in uneven fuel delivery.
Experts consider the UMZ 417 engine obsolete, like the rest of the units from the GAZ-21 family and under the hood modern cars they don't belong. 1
Engine UMZ 421/4213/4215/4216/4218 2.9 l
The power unit UMZ 421 became the most modern modification of the GAZ-21 engine and the logical development of the UMZ-217 model, but with a large volume, exhaust valves increased to 39 mm. In the newest versions, UMP 421 is already installed injection system fuel supply.
The UMZ 421 engine differs from the ZMZ 402 in thin dry liners, which increased the strength of the block, the cylinders are 100 mm in diameter, and the fingers are displaced in the pistons by 7 mm. Instead of anachronistic packing, a rubber cuff and other small parts are used.
At the same time, on a global scale, the engine has not changed and in fact it is the same unit of the mid-50s, but in an improved form.
Due to the lack of hydraulic lifters, clearances will have to be adjusted every 10 thousand kilometers.
The disadvantages of UMP 421 include a curve design, which affects the occurrence of jerking, vibrations and other things.
Engine knocking occurs due to unadjusted valves, connecting rod bearings or camshaft.
Overheating of the motor occurs due to a defect in the thermostat, pump or airlock in the cooling system.
The advantages of UMP 421 include high-torque, availability of spare parts and full maintainability... If you take care of the engine and do not overload it, then the resource will be at least 200 thousand kilometers.
Engine ZMZ 409.10 / 4091.10 / 4092.10 / 4094.10 2.7
The basis for the large-volume ZMZ-409 engine was the ZMZ-405, which uses a crankshaft with a stroke increased to 94 mm, the old connecting rods, modified pistons displaced by 4 mm. Otherwise, it is the same 405 with the same cylinder block height, thinner inter-cylinder bridges, and cooling slots. The torque has increased due to the performance increased by 7 "horses", and the latest engine modifications comply with the Euro-3 eco-standards.
The faults include jamming of the timing chain tensioner, but the valve does not bend.
A thermostat or a clogged radiator is to blame for engine overheating.
Thrust failures are the "handiwork" of the ignition coils, which must be replaced otherwise the engine will break down.
Knocks occur due to the hydraulic compensator, which requires replacement.
Plugs, connecting rod bushings and compression affect the engine tripping.
