From this small guide you will learn how to replace the clutch on a VAZ-2112. This car has earned popularity among young people and older generations. Yes, the car is still far from being comparable to prestigious foreign cars, but it has everything you need: a very playful and powerful engine, a comfortable interior, and a rather attractive appearance. And this is all that is necessary for an unpretentious person. And the most important thing is the low cost of maintenance. Spare parts for a 12 Series car cost much less than for foreign cars. In addition, many components from older “nines” and “tens” are suitable for it.
What is clutch?
Before you go to a car service center in Moscow or another city, try to figure out how to properly replace the clutch on a two-wheeler. As you can see, there is nothing complicated in the work procedure. You can complete all repairs yourself in a few hours.
The clutch is a mechanism that allows you to disconnect the engine crankshaft and the primary gearbox. As a result, the engine can work, the gearbox lever can be in a gear position, and the car will stand still.
A clutch is needed in order to change gears while the car is moving. If it were not there, then changing gears would be problematic - the lever is very difficult to move from one position to another. And all because the engine crankshaft and the wheels of the car are rigidly connected. And it is the clutch that allows for a kind of disconnection of the power units.
When repairing a car in a car service center in Moscow or any other city, you need to carefully ensure that the technicians complete all the work to the highest possible quality.

Clutch on VAZ-2112
This is what the VAZ-2112 clutch diagram looks like in disassembly.
The clutch on any car, including the VAZ-2112, plays a very important role. So, without his participation it would simply be impossible to transmit torque from the engine to the gearbox.
Due to the fact that this element bears a large load, it can absolutely be called a consumable material, because its main elements require immediate replacement if they are severely worn.

Step-by-step work order
Replacing the clutch without removing the gearbox
Before proceeding directly to replacing the clutch, you need to remove the gearbox. How to do this quickly and efficiently is written in this article.
When the clutch is dismantled, we continue work:
- Using a spanner, unscrew the bolts securing the clutch housing.

When is replacement necessary (symptoms)?
You can understand that the clutch needs replacement by the following signs and behavior of the car:
- Vibration occurs when pressing the clutch pedal.
- When you press the clutch pedal you hear a humming noise.
Basic clutch elements
Now let's look at what main elements are included in the design:
- VAZ-2112 clutch drive disc (usually called the “basket”). It is installed on the flywheel and secured with bolts.
- Driven disk. It stands inside the “basket” and is connected to the gearbox input shaft using a splined connection.
- The release bearing is an element that allows you to act on the petals of the basket. With its help, the slave disk is disconnected from the master disk.
- Clutch cable - allows you to transmit force from the pedal to the release bearing.
- The clutch pedal, which the driver operates with the force of his foot.
These are all the basic elements that are present in the design of a car clutch. It is worth noting that the “two-piece” uses a cable drive system, which is much cheaper than a hydraulic one. But it is much worse in terms of convenience - the pedal is tight, this is especially noticeable on older cars. And if you want the clutch on your car to be as soft as possible, change the cable in a timely manner, do not wait until it breaks.
Symptoms of a problem
I think you understand that doing the replacement quickly with your own hands will not work, but you can save a lot and spend money only on the necessary spare parts. To the question of when a VAZ 21124 clutch disc needs to be replaced, we answer - in order to reduce the chances of getting into an accident, you should detect and fix problems in a timely manner, and the clutch is no exception. Let's consider the main signs of the need to repair or replace the clutch disc:
- The appearance of the smell of burnt plastic is impossible to confuse with anything else. Remember, if your clutch starts to burn, then you can’t delay repairs, things will only get worse. A simple example from personal experience: a driver smelled a burning clutch, but continued working for another day, and only then stopped at a service station. The result is this: instead of replacing just the driven disk, I had to grind the flywheel (the grooves were rubbed with rivets) and replace the entire basket, since the springs lost their elasticity due to overheating, and the cost of repairs tripled. Keep in mind the smell of a burnt clutch means serious problems are approaching; every hour is expensive here.
- When the gears stop shifting, it usually becomes more difficult to press the pedal at first, then problems appear with shifting and, finally, the gears stop shifting at all. It is better to take preventive measures and not bring it to this state; it is better to promptly replace the clutch disc in the VAZ 2112.
Necessary conditions and tools
Replacing clutch discs on a VAZ 2112 requires certain conditions and tools:
- Inspection pit, or overpass, or lift
- Set of sockets, set of keys
- Special centering mandrel, or old gearbox input shaft
- Slotted screwdriver (flat)
- Stops or “shoes” for wheels
- Pliers
- Clean rags
- A little grease for the gearbox input shaft
- An assistant (firstly, it will speed up the work, and secondly, removing and installing the box alone is a violation of safety regulations)
Symptoms of a node malfunction
Before replacing the clutch on a VAZ-2112, you need to figure out whether it needs to be done at all.
Among the signs of malfunctions are the following:
- When you press the gas pedal, you can hear the engine picking up speed, but the car does not go faster. This indicates that the clutch is slipping, there is practically no connection between the driven and driving discs.
- Extraneous sounds are heard when the car moves - this may indicate the destruction of some system components. As a rule, at the same time as these sounds, the system also fails.
- A hum is heard when you lightly press the pedal - a clear sign of a faulty release bearing.
- The pedal falls through - most likely the VAZ-2112 clutch cable has broken. This is the most harmless thing that can happen.
- If the cable is intact, but the pedal falls and the clutch does not release, then the release bearing has collapsed. Unfortunately, this also happens sometimes.
Knowing all the signs of breakdowns, you can begin repairs. Replacing the clutch on a VAZ-2112 with your own hands is not difficult. You just need to know the order of the work.
The last step is adjusting the pedal
As follows from the car's operating manual, the travel of the foot clutch cannot exceed 125 millimeters.
In this case, the boundary tolerances are no more than 0.5 cm in both directions. The limit above which a car cannot be operated is 16 cm. Having finished with the theory, we proceed to the practical implementation of the task. First measure the actual pedal stroke. Place the ruler at its bottom - keep it strictly parallel to the floor. If the values are within the limits mentioned, then adjustment is not necessary.
Otherwise, move to the fork - here, as previously noted, there is a finishing mechanism. First, loosen the lock nut, and then, using a wrench, rotate the one above it to make the adjustment.
At the end of the procedure, measure the stroke - if everything is in order, then press the pedal several times to make sure that everything is working properly. Next, use the ruler again. Maintaining a normal indicator means that you did everything right.
Return to the fork and secure the position of the adjuster with the locknut.
An important point: it is advisable to make sure that in the end the pedal that releases the clutch is below the gas level. This speeds up the response of the mechanism and significantly reduces its wear.
Dismantling the gearbox
The most important thing is to remove the gearbox. Therefore, it is best to carry out all work on an inspection hole or overpass - it’s really more convenient. Procedure:
- Remove the left wheel, unscrew the nuts from the ball joint and the tie rod end. You will need to move the box to the side; the drive on the left should come out without any problems.
- Loosen the nut securing the rocker and remove it from the gearbox shaft.
- Remove the starter, having first disconnected the battery and all wires from it.
- Unscrew the fastenings of the pillows holding the box. It is recommended to place a jack or reliable support under the gearbox housing before doing this.
- Disconnect the speedometer cable, disconnect the wires from the reverse sensor, as well as the ground bus.
- Unscrew the three bolts and nut that secure the gearbox housing to the engine block.
- Carefully move the box to the side; the right drive must be removed.
A little about how to properly remove the box:
- Firstly, you cannot remove both drives at once - replace one with a tube that will hold the differential.
- Secondly, it is imperative to drain the oil from the gearbox crankcase. By the way, why not replace it?
Clutch installation and assembly
Replacing the clutch on a VAZ-2112 is carried out according to the following algorithm:
- Unscrew all the bolts that secure the basket to the flywheel. If you plan to install it again, then you need to unscrew the bolts evenly, crosswise. The main thing is not to damage the basket.
- Remove the basket and disk, install new elements in their place.
- Tighten all the bolts (be sure to use new ones, since the old ones are threaded) and install the guide sleeve.
- Tighten the bolts evenly, crosswise.
- Remove the old release bearing and install a new one.
- Reassemble everything in reverse order.
This is a short tutorial, but the hardest part is lifting and lowering the box, as it is quite heavy.
Replacing the clutch cable
The price of replacing a clutch on a VAZ-2112 is quite high - you will have to pay about 3,000 rubles for more or less high-quality spare parts, and at least the same for labor. But if you do everything yourself, you can save a lot of money.
Replacing the cable is much easier. The old one needs to be dismantled, and the new one needs to be fixed on the pedal and fork. The most difficult thing is to stretch it from the engine compartment into the cabin: the hole is quite small, and there are no amenities. But everything is doable, and all the work will take you, including preparation, no more than half an hour.
