Do-it-yourself replacement and adjustment of the VAZ 2106 clutch

1 - clutch housing, 2 - working cylinder rod, 3 - fork, 4 - adjusting nut, 5 - lock nut, 6 - return spring, 7 - friction linings, 8 - driven clutch disc, 9 - steel casing, 10 - drive disc ( basket).

Today, the article will talk about procedures such as replacing and adjusting the 2106 clutch with your own hands. As we like to repeat, everything can be done without the help of car service specialists; there are no difficulties in repairing VAZ cars and there cannot be any. Often, drivers try to solve all the problems with the car on their own, because the cost of maintenance is absurdly high.

Even despite the fact that the VAZ 2106 has not been produced for ten years. And we will try to help as much as possible with the repair. If you have any questions, leave comments, share your experience, and describe unusual situations. After all, the topic is quite interesting and rich.

Clutch mechanism of a VAZ 2106 car

Description of design

1 - guide sleeve, 2 - basket
You all know that the clutch pedal is installed in the driver’s feet. For some, this is enough and they don’t go any further. But if you’ve already decided to take on the repair, you’ll have to study the entire rest of the chain. On the VAZ 2106, like on all other classics, the clutch drive is hydraulic. The pedal drives the master cylinder rod, which moves a small piston inside it.

An expansion tank is connected to this cylinder. On 2106 and similar VAZ models it is located on the partition between the engine compartment and the passenger compartment. It is worth noting that on nines and newer cars the expansion tank was installed directly on the cylinder body - a significant saving in space and a slight increase in reliability. After all, rubber tubes tend to wear out and leak brake fluid.

Clutch failure

The clutch can fail for several reasons:

1. Resource development.
2. Presence of a manufacturing defect.
3. Harsh operation.
4. Mechanical damage during operation.

Very often, the cause of premature failure of VAZ 2106 clutch elements is the presence of manufacturing defects and increased loads. In particular, traffic jams in the city make themselves felt quite quickly.

Symptoms of malfunctions

Depending on the type of breakdown, the following symptoms may appear:

1. The clutch pedal fails, the engine and gearbox shafts do not open.
2. The clutch works, but there is an extraneous sound.
3. The engine picks up speed, but the speed does not increase - the clutch slips.
4. Shifting gears is difficult, the clutch “leads” and does not disengage completely.
5. The appearance of leaks from the expansion tank, pipes, cylinders.

It has already been said that the master cylinder is mechanically connected to the pedal. But the clutch fork and slave cylinder are mounted directly on the gearbox. With the help of these mechanisms, the release bearing moves along the axis of the input shaft.

How does the clutch drive work?

The operating principle of the entire clutch drive mechanism on a VAZ 2106 car is as follows:

1. The driver presses the pedal.
2. The rod moves and along with it the piston in the cylinder.
3. The pressure in the pipeline between the main and working cylinders increases.
4. Due to the increased pressure in the working cylinder, the piston and rod move, which drives the clutch fork.

After all this, the VAZ 2106 clutch disc and the basket move away from each other, the crankshaft does not rotate the primary one. Therefore, the car does not move. And now about the repair procedure.

Bushing, cover VAZ 2101-07, 2121-213 release bearing guide with oil seal

Dear customers, in order to avoid errors when sending the front bearing cap for VAZ 2101-2107, please indicate your car model and year of manufacture in the “Comment” line.

The gearbox is designed to change the torque developed by the engine in order to obtain different traction forces on the drive wheels when starting the car, accelerating, moving and overcoming road obstacles; changes in vehicle speed and direction; the possibility of driving the car at low speeds, which cannot be provided by the engine, and disconnecting the engine from the transmission for a long time when parked or when the car is moving by inertia (coasting).

Preparing for repairs

Before putting the car in a pit and removing the box to replace the clutch, you need to visit the store and buy all the necessary spare parts:

1. Clutch disc.
2. Basket (drive disk).
3. Release bearing.
4. If necessary, clutch fork.
5. If there is significant wear, the crown on the flywheel will also need to be replaced.
6. Bolts securing the basket to the flywheel.

It is also important to have a good set of tools on hand, WD-40 penetrating lubricant, sometimes even a gas torch is necessary (if the bolts and nuts are very rusty).

It is advisable to carry out all the work in an inspection pit or overpass (it is unlikely that the average driver of a six will have a lift in the garage, so we do not mention it). If everything goes smoothly and the nuts unscrew well, you will complete all the work very quickly.

Place the car on the pit, fix it in one position by placing stops under the wheels. All work is divided into two stages: under the car and above it. Please note that there is no need to drain the oil, since if you dismantle it carefully, you will not spill a drop.

And don't forget about the alignment of the clutch disc. The price of a special device is quite high - about 500 rubles. but you can use a small piece of pipe without any problems, as long as the diameter is suitable.

Work on top of the car

So, a start has been made, the goal is to remove the gearbox to replace the clutch. On VAZ 2106 and similar cars this is done quite quickly, it is only important to follow a certain sequence:

1. Inside the car, remove the gear shift knob. It is attached using plastic latches. Sometimes difficulties arise with dismantling, and it gets to the point where the latches break off. The price of a new set of fastenings is no more than one hundred rubles, and you can purchase it even after repairs have been carried out. Therefore, do not be afraid if you suddenly break the plastic antennae.
2. Go to the engine compartment, unscrew the four nuts that secure the exhaust pipe to the manifold. The fact is that the exhaust pipe will interfere with the removal of the box, but it is enough to move it a little to the side.
3. Disconnect the battery and remove it from the car.
4. Unscrew the two top bolts of the starter, disconnect the power wires for the windings and the solenoid relay from it.
5. Disconnect the ground wire that goes to the gearbox.

Carefully inspect whether there are any “upgrades” on your vehicle specifically that will interfere with the removal of the transmission. If there are any, then make sure that they do not complicate further repairs.

How to change the release bearing on a VAZ 2114 with your own hands - step-by-step instructions with a disassembly diagram

It was previously noted that the process of replacing the VP is difficult precisely when removing the gear shift unit, so first study the device to understand the intricacies of dismantling.

List of necessary tools for replacement:

• Two jacks and supports;
• Set of spanners with ratchet;
• Mount;
• Minus screwdriver;
• Torque wrench;
• Container for draining oil.

Work under the car

This is perhaps the most difficult part of the entire repair, since there are many more steps to be taken here. So make yourself comfortable and proceed to the following operations:

1. Unscrew the last (lower) nut securing the starter and remove it. This nut is the nastiest, since it is difficult to get to it using simple wrenches; you will need to use a socket, a ratchet and a cardan. True, it was possible to work with an ordinary open-end wrench installed in the end.
2. Unscrew the suspension bearing mount.
3. Disconnect the cardan and rear axle flange. Hold the bolt head from turning with a 12mm open end wrench.
4. Apply sharp blows to the driveshaft to dislodge it from the rubber coupling on the transmission shaft. Move the cardan to the side.
5. Unscrew the mounting of the pillow, install a support under the gearbox.
6. Remove the slave cylinder from the clutch fork. Be careful not to lose the bar underneath and the spring.
7. Remove the speedometer cable.
8. That's all, now all that remains is to unscrew the four bolts that secure the box to the engine block.

Remove the gearbox carefully, try to move it as far as possible from the engine block. The fact is that you can damage the VAZ 2106 clutch drive disc. And this is quite easy to do.

If we take nines and newer VAZs as an example, then the clutch drive discs on them are more reliable and durable. It is advisable to set the gearshift lever to the position corresponding to the third speed.

Clutch replacement

Please note that it is imperative to install new clutch basket mounting bolts. On old ones, the threads already have minor deformations, therefore, the connection will be very unreliable. The price of all elements will be approximately 2000-2500 rubles.

If you prefer foreign-made units, it will be more expensive. However, it is worth wondering about a simple truth: the service life of imported ones is sometimes shorter than domestic ones, and the price can be twice as high. Why pay extra money? And in general, if the price of a car is 20-40 thousand rubles, why invest a lot of money in it?

But let's return to the replacement procedure. Unscrew all the bolts from the basket, remove it and the clutch driven disc. Install new elements in the same way, but tighten the bolts, do not tighten them. It is advisable to look at the condition of the crown before installation. If it is deplorable, then you should immediately install a new one.

In stores, its price is about 200-250 rubles, which is not very expensive. But you can reduce the cost of repairs by simply removing the crown, heating it and installing it on the reverse side. But you will have to buy a new one if this procedure was previously performed.

Pay attention to the VAZ 2106 clutch fork; if it is damaged, be sure to replace it. A new release bearing is installed in any case. You can apply CV joint grease to it, for example. This can slightly increase its resource.

Almost finished, all that remains is to take the guide sleeve and install it in the hole of the clutch disc. Without removing the shaft, tighten all the basket mounting bolts crosswise. Do not allow distortions, otherwise the clutch will not work correctly and its service life will decrease.

That's all, the clutch replacement was completed successfully, now all that remains is to assemble the car. But here no difficulties will arise, since all the actions are the opposite of those that were described in detail in this article. If you also need to replace the brake fluid in the drive system, then read on.

How to replace?

If you have no idea what a VPS is or what a clutch disc looks like, then entrust bearing repair work to professionals. If you think that you can cope with this, then we suggest that you familiarize yourself with our car repair manual.

Which to choose?

Selecting an IPS is the first point that must be completed if you decide to replace an element.

There is nothing difficult in choosing an element. Classic VAZ models (2010 - 2107) are equipped with a release bearing of the same type. Just buy the appropriate part at a car store or market, indicating the model of your vehicle. To make it more clear to you what the UPS looks like, you can look at it in the photo below.

What will you need?

What you will need to replace the UPS:

• the new UPS itself;
• flat head screwdriver;
• set of wrenches;
• lubricant "Litol-24";
• jack as support.

Bleeding the system

Draining fluid from the clutch drive system is very simple:

1. Using a blower, pump out the liquid from the expansion tank.
2. Unscrew the fitting on the working cylinder and wait until all the fluid is gone.
3. Press the clutch pedal several times to remove any remaining brake fluid.
4. Change tubes if necessary.
5. Tighten the fitting.
6. Fill the reservoir with fresh brake fluid.
7. Place a transparent tube onto the fitting.
8. Have an assistant press the clutch pedal several times. With the last press, you need to hold it in the extreme position.
9. Unscrew the fitting half a turn, allowing fluid and air to escape.
10. Repeat the procedure until liquid begins to flow without air bubbles. Don't forget to monitor the level in the expansion tank.

In fact, two or three passes are enough to get rid of air in the system. As you understand, pumping the clutch on a VAZ 2106 is not difficult. The procedure is very similar to bleeding the brakes, only it is much faster - the line is very short.

After replacing the clutch, it will need to be adjusted. Pay attention to the working cylinder rod - it has a thread along which you can move the nut. It is by moving it that the clutch is adjusted on VAZ 2106 cars and the rest of the classic series. It is also possible to adjust the free play of the clutch pedal; for this purpose, a special bolt is provided directly above it.
