The clutch is a special mechanism in a car, the work of which is based on the action of the sliding friction force (friction clutch). This mechanism is designed for direct transmission of torque.
In addition, the clutch plays one of the main roles in driving cars, since it is on it that the smoothness of gear shifting, short-term disconnection from the flywheel located on the engine, transmission, and torsional vibration damping depend.
In the modern world, the very definition of "grip" refers directly to the power train (transmission) component of a vehicle. The transmission component itself is designed to disconnect and reconnect the connection between the transmission and the heart of the vehicle, the combustion engine.
In general, historically, the clutch was invented by the famous scientist Karl Benz.
In the automotive nature, the clutch serves to temporarily disconnect the engine crankshaft from the power train of the vehicle. This, in turn, is necessary when shifting gears in the gearbox itself. In addition, it is necessary when the vehicle is partially braking and when the vehicle comes to a complete stop.
In addition, the clutch allows you to calmly and smoothly launch your vehicle (without jerking). Clutch is present on both tractors and combines, that is, on almost all land vehicles.
Now it is necessary to describe the clutch release drive itself. Thus, it consists of: the clutch master cylinder, which is immediately behind the pedal, the clutch pedal itself, the clutch slave cylinder, which moves the pressure bearing and the fork, the clutch release fork, the pressure bearing and the piping system.
The cylinders are an integral part of the clutch. There are two of them in the automotive nature: the clutch master cylinder and the clutch slave cylinder. The device of the clutch master cylinder is not particularly difficult: cylinder, housing, cuffs, piston.
The main task of the clutch master cylinder is to transmit force to the working pedal directly from the pedal, using the working fluid.
1. When we start repairing the clutch slave cylinder
The clutch slave cylinder has a special arrangement and is traditionally located on the clutch housing. The device of the clutch slave cylinder has no fundamental differences on various models and brands of cars. That is why the whole principle of repairing or replacing the clutch slave cylinder is the same, both on new foreign cars and on ancient domestic cars.
In order to make it possible to independently repair or replace the clutch slave cylinder, it is necessary to know the device itself and the technology for its disassembly. This procedure (disassembly) of this mechanism is quite simple, if certain aspects are observed when trying to penetrate inside the entire device.
There are several very important elements directly in the cylinder body, the failure of which cannot guarantee the successful operation of the entire clutch system.
Thus, in the cylinder body are located: the piston, the pusher, the O-rings, the spring and the air outlet.
In general, the total replacement of the clutch slave cylinder assembly is already the last measure when there is no other way out of the situation. This is because the existing repair kits are already equipped with the most wearing parts. Nevertheless, in recent years, the quality of rubber parts has been poor.
The first sign of a malfunction and clutch malfunction is the failure of the clutch pedal or its overly soft stroke. But still, this is not a reason to immediately start repairing the hydraulic drive. In order to lower your passions and experiences a little, you need to carry out a full pumping of the clutch hydraulic drive.
Problems can arise when air is detected in the brake fluid during bleeding of the hydraulic clutch. If this happened, then you need to think about where he could come from. Often, if air appears in the hydraulic drive, this indicates a leak in the rubber seals.
It is quite easy to bleed the clutch hydraulic drive. A hose must be connected to the bleed screw itself on the working cylinder. Its other end must be lowered into a container with brake fluid. After that, you need to fill the reservoir of the clutch master cylinder with the same brake fluid from the container.
Until this moment, you need to check for traces of external fluid flow, which may be on the pipeline, both cylinders and at the joints.
2. Repair of the clutch slave cylinder
Repair of the clutch slave cylinder must begin with its removal and disassembly. This requires a vice and a metalwork tool. After removal, you need to place the slave cylinder in a vice to make it easier to disassemble.
First, you need to remove the protective cap together with the pusher. After that, it is necessary to remove the piston and remove the retaining ring, which is located on the piston. The O-rings and spring must be removed from the piston. After that, it is important to clean the air outlet and all openings that are in the cylinder.
Further, you need to make sure that there is no mechanical damage in the cylinder mirror and the outer surface of the piston. If there is any mechanical damage to the spring, it must be completely replaced. All O-rings, rubbers and protective caps must be replaced with new ones. After that, you need to rinse all parts with clean brake fluid.
Gasoline, oil, "diesel fuel" are excluded for flushing, as this may cause swelling of all rubber parts that were to be flushed. For the hydraulic drive itself, it is necessary to use a high-quality brake fluid. The assembly itself, as well as the installation of the working brake cylinder, will be carried out in the reverse order.
There should be no extra parts left after the complete assembly of the cylinder. There can only be those that were not used from the clutch slave cylinder repair kit. After a complete repair of the clutch master cylinder, or only a worker, has been made, it is imperative to bleed the hydraulic drive.
Repair or complete replacement of the clutch slave cylinder is a necessary procedure in case of certain clutch malfunctions. With all this, you can either completely replace the entire working cylinder, or partially replace only those parts that have been damaged.
If more serious problems arise that have not been indicated in this article, then the essence of the whole problem does not lie in one slave cylinder, but there may be damage to the entire mechanical clutch system.
Thus, if you look at all the above recommendations, then it can be noted that partial repairs or complete replacement of the working brake cylinder are not complicated procedures and can be carried out even at home.
There is one piece of advice that can extend the life of both individual elements - the clutch slave cylinder, and the entire clutch system of a vehicle. It is enough just to keep an eye on your "iron horse", take care of him, and most importantly - change the oil on time for an even better one.
