In cars with a manual transmission, the clutch needs to be replaced periodically. To replace the mechanism with your own hands, you need to stock up on special equipment and instructions for performing the replacement. If your car's disk mileage ranges from 70 to 150 thousand kilometers, then you should replace the clutch.
But you also need to take into account the operating conditions of the car and the manufacturer of the clutch mechanism that is installed in the car. After analyzing all these factors, you can watch a video about replacing the clutch with your own hands.
Changing the clutch yourself
The cost of a complete clutch replacement can vary depending on the quality of the parts and the availability of the necessary tools for the job.
If you decide to do everything yourself, then without a new release bearing, clutch, disc and basket, cylinders, cable, you will not be able to complete the complete replacement process.
Steering wheel beating or vibration after repair
Oddly enough, beating of the steering wheel or the entire car can occur immediately after a car service. If the problem is discovered after manipulations affecting the chassis, it is logical to look for the root cause in repairs.
Most often, the sudden appearance of vibrations when braking at high speed is preceded by the installation of new parts:
- brake rotor;
- hub assembly, including a new bearing.
In most cases, this is due to the use of defective spare parts; less often, the cause is poor-quality installation of parts.
If the steering wheel or the entire car begins to shake after repairing the chassis, you should contact the car service center where the work was carried out.
How to properly remove and install a gearbox
If you have a rear-wheel drive car, first disconnect the clutch that connects the manual transmission to the driveshaft. And if your car is equipped with a front-wheel drive mechanism, then start by removing the drive shafts, do not forget to install plugs during replacement. Now disconnect the cables.
Unscrewing the nuts on the mount, remove the input shaft, which is located in the bearing inside the engine flywheel. The appearance of oil stains in the area of the rod indicates a problem with the seal.
Let's start the installation. From special equipment, you will need a winch to rotate the shaft on the gearbox during installation. This way it is guaranteed to fit into the splines that are located in the flywheel. The last stage of installation is the process of adjusting the length of the rod.
Rear wheel drive car repair
Replacing the VAZ-2101-2107 clutch basket is quite simple, but before doing this you need to remove the box. To do this, perform the following steps:
- Disassemble the gear shift lever.
- Disconnect the battery (just remove the negative terminal).
- Unscrew the exhaust manifold mounting nuts.
- Remove the starter. To do this, unscrew all three nuts that secure it to the clutch block.
- From the bottom of the car, dismantle the driveshaft - unscrew the four nuts on the flange and on the hanging bearing (from the body).
- Unscrew the nuts that secure the gearbox mount.
- Remove the clutch slave cylinder and move it to the side.
- Disconnect the ground wire.
- Disconnect the wires from the reverse signal sensor.
- Unscrew the speedometer cable.
All that remains is to unscrew the four bolts and remove the gearbox. Only this must be done carefully, otherwise you may damage the basket.
Independent work on replacing disks and baskets
You need to start the repair process by unscrewing the bolts in the basket, then you should remove all the parts that are in the flywheel. Pay attention to the surfaces of the flywheel so that there are no traces of oil there.
The driven disk must also be clean; if there are marks, the oil seal must be replaced. Also change the driven disk and basket if you find damage on them in the form of deep scratches. The flywheel and driven disc of the basket must be clean and free of grease. Cleaning can be done with gasoline.
We insert the disc into the basket and put the mount either on the manual transmission input shaft or on the mandrel. There is a hole in the flywheel where we place the entire set of parts. Insert until it stops and screw the basket onto the bolts.
This process must be done two or three times to ensure an accurate and even installation. Now you can tighten the bolts, applying a force of 2.5-3.5 kgf/m. Information about the force power is available in the repair instructions for your car brand. We change the clutch basket according to a similar scheme.

You have replaced the clutch and feel vibration in this area - you need to adjust the centering of the disc or check the tightening power of the basket.
Requirements for repairs
Please note that the clutch basket and clutch disc should fit each other as closely as possible. No distortions should be observed, otherwise extraneous noise and vibration will appear during engine operation. It is advisable to change the entire set completely:
- Drive disc (clutch basket).
- Slave.
- Release bearing.
- Basket mounting bolts.
- If necessary, clutch drive (cable or cylinders).
Only in this case will you receive a guarantee that the node will function correctly and stably.
Changing cylinders
There is a reason to change the main cylindrical system if the functionality of the system does not improve after replacing the o-rings. Replacement with new clutch cylinders is installed when the brake fluid runs away even after replacing new cuffs.
Perform the process of removing the working cylinder and installing it according to the following diagram:
- We get rid of the spring near the pedal.
- We unscrew the two nuts that secure the cylinder to the gearbox;
- The process of unscrewing the rubber hose attached to the working cylinder is carried out by weight;
- We screw a new type cylinder to the hose to avoid leakage of the brake compound;
- We pump everything out of the cylinder, unscrew the fitting, close the hole;
- We unscrew the nuts that secure the master cylinder to the car body;
- To release the hinge connected to the pedal, you need to pull it towards you. Pull out the pin, this will release the cylinder from the pedal.
- Install the two cylinders in the same way as you disassembled them.
After replacing the cylinders, bleed the main clutch. When the air stops escaping, the cylinder is installed correctly.
Removing the gearbox on a front-wheel drive car
To ensure that replacing the clutch basket does not cause problems, it is necessary to completely remove the gearbox. Of course, you can move it to the side, but there is practically no convenience. Therefore, do the following:
- Disconnect the battery.
- Remove the starter.
- Unscrew the ground wire fastening.
- Remove the speedometer cable.
- Unscrew the nuts securing the cushions to the gearbox.
- Remove the rocker - a moving mechanism that is located between the gearshift lever and the gearbox.
- Remove the clutch cable.
After removing three bolts and one nut, you will be able to slide the transmission to the side and remove it completely for repair. But you need to comply with general requirements no matter what kind of car you have - front-wheel drive or rear-wheel drive.
Replacing the clutch slave cylinder
First, we disconnect the cotter pin element, which drives the hydraulic drive mechanism itself, using pliers. We use them to remove the spring. We do not scroll the fitting hose completely.

Steering wheel shakes when braking
The VAZ-2170 (like many other models) has front disc brakes. Therefore, it is worth considering possible problems in this case. When the steering wheel shakes when braking at speed, there are three reasons. These are crooked wheels, worn brake discs or wheel bearings. If the brake disc is curved, then the pad will follow the shape of this surface. Thus, due to the curvature, the wheel rotates unevenly. This happens due to great inertia. If you start to rock the wheel, it will resist. At speed this resistance is especially high. Therefore, vibrations are felt both on the steering wheel and on the pedals.
Replace the cable and release bearing
Replacing these parts is advisable after exceeding the 150 thousand mileage mark of the car. By freeing the fork from the spring, you can remove the cable. Unspinning the connection will make it possible to remove the cable from the clutch pedal.
If necessary, replace the entire part. To remove the spent cable, you need to pull out the pin. We install the new one using the same method as you removed it.
You know your car better than anyone, so armed with the appropriate equipment and tools, you can replace the clutch yourself without much difficulty.
Gazelle clutch: which one to choose
Today you can find products from various manufacturers on sale. However, some clutch kits are soft and smooth, but may have a shorter service life, while others operate more harshly, but handle loads better and last longer.
Different manufacturers independently determine the number of springs. The material used to make the friction linings may also differ, there may be unique manufacturing features for the release bearing, etc.
If we talk about the clutch manufacturers themselves, SACHS, LUK and VALEO are considered to be the market leaders. The Sachs clutch is traditionally considered reliable and durable, but some complain about being too stiff.
The LUK company is famous for its high-quality baskets, which allows full transmission of torque and ensures sufficient softness of the mechanism. The VALEO clutch is soft, the comfort is high, but the service life is somewhat reduced.
Let us also add that when designing a clutch assembly, the world's leading manufacturers separately take into account the power of the internal combustion engine, the operating features of the gearbox, the drive axle gearbox, etc. At the same time, cheaper analogues from unknown manufacturers may be of significantly worse quality or manufactured without taking into account certain characteristics and indicators.
For this reason, it is better to choose clutches from well-known brands, even taking into account the high cost. Otherwise, the mechanism may fail, for example, after 15-20 thousand km, and not after 80-90 thousand.
Clutch is more than just smooth gear shifting
First, let's look at why a clutch is needed at all and what work it does. As a rule, all knowledgeable people will say the same thing. The clutch is needed to ensure smooth engagement of the gearbox speeds, and for this purpose it temporarily disconnects the engine from the gearbox. Thus, the car engine is not overloaded, and gear shifts occur smoothly. In addition, thanks to this mechanism, rapid wear of engine and gearbox parts is prevented. It is clear that the engine is not overloaded when changing gears, and there are also no overloads that arise due to the rotation of engine parts when the crankshaft speed suddenly slows down.
In addition, if the car’s clutch is working properly, then the car will always move off smoothly and unpleasant situations will not arise when starting under a traffic light, or indeed when changing gears
Well, this is very important to know: if you don’t treat the clutch properly, it can also be subject to premature wear. In particular, with a rather aggressive driving style, this vehicle mechanism receives loads that affect its wear.
The device should be handled with care to avoid frequent problems in the future.
