Of course, no one would dispute the importance of the friction clutch in the driving system. Simple procedures for setting up this unit will significantly reduce the risk of wear on parts. Skills for pumping a hydraulic drive will not be superfluous, because any intervention in the system, be it replacement of the working cylinder or a drop in the fluid level in the drive reservoir leads to airing of the system.
It is recommended to check the settings regularly at every car service. But there are still signs when the procedure should be started immediately, so it will not hurt any owner to know how to pump the clutch on a VAZ 2107 on their own. Malfunctions in the operation of the coupling during operation are expressed by the following symptoms:
- Slips - the clutch disc slips when the pedal is fully released, and is not able to transfer all the power from the internal combustion engine to the transmission.
- Leads - the disc does not move away from the flywheel when the pedal is fully depressed, which makes gear shifting difficult.
What do you need to check?
The clutch may engage too sooner or later due to the pedal travel being disrupted, resulting in jerky movements. Pedal free travel should be within 0.4-2.0 mm, if these indicators are violated, then you cannot do without adjustment.
If you look under the car, you can check the free play between the pusher (indicated by the red arrow) and the release fork (blue arrow). Before adjusting the clutch on the VAZ 2107, you need to shake the fork by hand, if there is no free play or exceeds 5 mm, then adjustment of the unit is necessary, because the release bearing will be subject to constant loads.
In the case when all the parameters of the adjustments are normal, then the pedal travel before the start of the clutch engagement should be 25-35 mm. This is determined using a ruler, if the indicator does not correspond to the norm, then some components of the clutch drive system will have to be adjusted.
It's simple: how to correctly adjust the clutch on a VAZ 2107 car without the help of specialists?
There are two parts to the complete adjustment of the friction clutch control system, one performed in the passenger compartment and the other under the vehicle from the inspection pit. To work you need a set of tools:
- A set of keys.
- A set of screwdrivers and pliers.
- Ruler or square.
A bracket with a pusher is installed under the steering column in the cabin. By rotating the nuts, you can achieve the desired clearance between the pusher and the piston of the clutch master cylinder. It is this parameter that is responsible for the initial free travel of the pedal, the adjustment technology is quite simple:
- Use a wrench (picture no. 1) to hold the travel stop, and with the second wrench, unscrew the lock nut by two turns.
- Turning the limiting pin with the first key (screw it in or unscrew it), set the required initial free travel of the pedal - 0.4-2.0 mm.
- Check the free play with a straight edge and, if necessary, repeat the adjustment procedure.
- Tighten the lock nut with a wrench.
Before pumping the clutch on the classic VAZ 2107, you need to perform the second adjustment stage, which is done on an overpass or inspection pit. The technology for checking and adjusting the clutch release fork free play is as follows:
- Disconnect the spring from the fork with pliers, and then from the slave cylinder. You can make a check without dismantling the spring, but when controlling the free wheel, you will have to apply force to overcome its resistance.
- Check the fork travel with a ruler, pushing it all the way. The readings should be within 4-5 mm, if there are deviations, then the following points should be followed.
- Clean the cylinder from dirt and spray the nuts with WD-40 grease.
- Using the keys "13" and "17", one hold the adjusting nut "a", while the other unscrew the lock nut "b".
- Fix the pusher with pliers and unscrew the nut "b" by two turns.
- Turning the adjusting nut with the "a" wrench, adjust the free travel of the fork. At the same time, hold the pusher with pliers.
- Tighten the pusher and adjusting nut "b" with pliers, and then fix the lock nut "a".
- Check the parameters of the free play of the fork, and if necessary repeat the process.
- Brake fluid.
- Rubber hose 50-100 cm long.
- Wrench "8".
- Container for liquid.
- Brake fluid.
- Fill the clutch reservoir with new fluid.
- Put one end of the hose on the connection of the working cylinder, and lower the other end into the container.
- Ask the assistant to press the clutch pedal 5-6 times and fix it in the pressed state.
- Loosen the fitting on the cylinder with a key "8" and release the liquid with air into the container, then screw the fitting and ask to release the pedal.
- Add liquid to the tank if necessary and repeat the operation until there are no air bubbles in the liquid.
- Start the car and turn on the reverse speed, the appearance of jamming or extraneous noise is unacceptable.
- Check the gear shifting while driving, if acceleration and shifting occurs without jerks and extraneous noise, then the clutch control system is set up normally.
Why and how to bleed the clutch on a VAZ 2107 car in your garage?
Bleeding is needed if the clutch does not completely turn off. For example, the pedal is depressed, the first speed is on, but you have not yet had time to release the pedal, and the car is already moving. A light pedal stroke also indicates the need to remove air from the system. The procedure should be performed with an assistant who will press the pedal. For work you will need:
Car owners who are interested in how to properly adjust the clutch on a VAZ 2107 car should know that pumping is carried out through a fitting located on the working cylinder under its bottom. The operation is no more difficult than , it can be performed even by a novice car enthusiast.
Pumping technique
It is advisable to carry out the work on an overpass or inspection pit; in extreme cases, the machine should be lifted on supports. Further actions are carried out on transitions:
During pumping, the liquid level in the tank must not be allowed to drop below 15 mm, and top up in a timely manner. Finally, you need to check the functionality of the coupling:
