Replacing the clutch disc on a VAZ-2104-2107

The clutch is the most important component of a car, without which it is impossible to imagine the operation of the gearbox mechanism, as well as the car’s performance of such operations as starting and braking to a final stop. In other words, the clutch is a necessary mechanism of any car, which is a kind of transfer point between the engine and the drive axles.

This unit includes:

driven clutch disc;
clutch basket and release bearing with clutch.

So what is this component of the clutch mechanism? This is a disc with spring plates and friction linings that are not connected to each other and are made of a material comparable to the material of the brake pads, i.e. abrasion resistant. In the center of the disk there is a hub with a splined connection.

Malfunctions

As a result of vehicle operation, the clutch disc, like any consumable material, can become unusable - the springs weaken, the friction linings wear out and become thinner. Manufacturers do not indicate a specific service life of the disk, because it depends only on the driver: one “clutch” can last only 5,000 km, while another can last 100,000. Increased clutch wear can result from:

sudden starting at high speeds;
slip;
incorrect adjustment;
participation in racing events;
leakage of foreign liquids.

Usually there are two faults for which it is worth considering repairs:

the clutch “slips”;
the clutch “drives”.

When slipping, the driven disk is not pressed completely against the flywheel. What does this mean? If you sharply press the gas pedal while the car is moving, you may notice an increase in engine speed, but there will be no increase in speed. In the end, the car will someday just stand up and only towing or muscle power can set it in motion. Therefore, the issue of replacing the driven disk should not be shelved.

When the clutch “drives”, uncharacteristic sounds and noises are observed when changing gears, gears are difficult to engage. In this case, the driven disk, on the contrary, does not completely “separate” from the flywheel. In this case, pumping the hydraulics and adjusting the free play of the clutch helps, which can be easily done by anyone in a garage. If you ignore this malfunction, you can run into expensive gearbox repairs.

Clutch kit price

Now, in the era of the development of the Internet, there is no need to run to stores and look for the necessary spare part. It is enough to have access to the World Wide Web and you will have any detail in a couple of clicks. Prices for clutch discs for the VAZ-2107 vary from 470 to 2000 rubles. The cost of replacement work in Moscow and the Moscow region is 2–2.5 thousand rubles.

What advice can you give when choosing a disk? First, rummage through the forums and read reviews. Secondly, when purchasing a disc, do not be lazy to inspect it. Examine the splines especially carefully - there should be no nicks or burrs there, otherwise there is a risk that the disk simply will not fit on the shaft or will not be removed during the next replacement.

Take a look at the friction linings: they should all be uniform in composition and free of cracks. Another point is the quality of the riveting. The key to quality here is the identical dimensions of the flange. Try to swing the damper springs; if there is play, then you should refuse the purchase. And the last thing worth paying attention to is the presence of markings on the damper plate.

Replacement

So, having purchased a new clutch disc, we proceed to install it. In order to slightly reduce the labor intensity, we will perform the replacement without removing the box. We carry out the work on an overpass or inspection pit.

Getting started with labor feats, we will carry out the preparatory stage:

Disconnect the negative terminal of the battery.
Remove the clutch slave cylinder.
We unhook the cardan from the gearbox.
Unscrew the speedometer cable.
Disconnect the wires of the reversing lights from the contact group on the gearbox.
We disconnect the clutch housing from the cylinder block and the cross member of the rear engine mount from the body.

Now we move directly to the main stage of our work - replacing the clutch disc:

We unscrew the nuts securing the gearbox support, move it back so that the gearshift lever rests against the back of the floor hole. The front part of the box will be held by the muffler, and a reliable support must be placed under the rear part.
Holding the flywheel with a mounting tool, unscrew the clutch housing mounting bolts, turning the crankshaft to gain access to them.
We move the clutch basket and remove the used driven disc, replacing it with a new one. Before installation, wipe the new disk and flywheel with a rag soaked in gasoline.

The installed disk must be adjusted relative to the center of the bearing at the end of the crankshaft.

We carry out further assembly in the reverse order, not forgetting to adjust the free play of the clutch pedal afterwards.

With simple manipulations, you can make the replacement yourself and save some money from visiting a service station. The main thing is not to miss the moment when the disk fails. No nail, no rod!

What you need to know to replace the clutch on a VAZ 2107 car

When talking about replacing a VAZ 2107 clutch, we mean a failed basket, disc, or release bearing. At the same time or separately, malfunctions may occur in the operation of the master cylinder, slave cylinder, release fork or clutch hose of the vehicle. If parts wear out during operation of the VAZ 2107 or after replacing failed ones with new spare parts, clutch adjustment may be required.

Clutch replacement

When replacing a basket or disk, you cannot do without removing the gearbox. That is, the box itself can remain almost in the same place; it will only need to be moved a distance sufficient for the gearbox input shaft to exit the clutch basket. However, for more convenient work, and for the purpose of visual inspection and possible replacement of elements such as the clutch housing, gearbox input shaft oil seal and rear crankshaft oil seal, it is better to remove the gearbox.

The price of VAZ 2107 spare parts, which may have to be replaced in this case, is not that high, and the time required to re-disassemble them to replace them will cost much more. The work is carried out on an inspection pit, overpass or lift. In general, first things first.

To dismantle the clutch, it is necessary to perform the following preparatory work:

Removing the starter.
Disconnecting the gearshift lever from the gearbox.
Removing the cardan shaft.
Disconnecting the clutch slave cylinder and the speedometer drive (flexible shaft) from the gearbox.
Removing the terminals (chips) from the sensor responsible for turning on the reversing lights.
Removing the exhaust system mounting from the gearbox.
Unscrewing the bolts that attach the gearbox to the engine.
Disconnecting the rear cushion (traverse) securing the gearbox to the body.

Next, you need to move the gearbox away from the engine to a distance sufficient for the input shaft to exit the clutch basket and rest it on the exhaust pipe of the car's exhaust system. To completely remove the gearbox, before unscrewing the bolts attaching the gearbox to the engine, it is necessary to additionally disconnect the exhaust pipe (pants) from the exhaust manifold.

All work on replacing the VAZ 2107 clutch in the same or slightly modified order was filmed long ago and posted on the Internet. So, if you wish, you can always familiarize yourself with it.

Design, principle of operation and procedure for self-replacement of the VAZ 2107 clutch

The VAZ 2107 clutch is the most important part of the transmission, involved in transmitting torque to the wheels. It is located between the gearbox and the power unit, transmitting rotation from the engine to the gearbox. Knowledge of the design features of the entire assembly and its constituent elements will make it possible, if necessary, to easily replace the clutch with your own hands.

Clutch device VAZ 2107

The clutch is controlled by a pedal inside the cabin. When you press it, the clutch is disconnected from the gearbox, and when you press it, it engages. This ensures a smooth start of the car from a standstill and silent gear shifting. The node itself consists of a large number of elements interacting with each other. The VAZ 2107 is equipped with a single-disc clutch with a central spring .

Clutch basket

The clutch consists of two discs and a release bearing. The clutch used on the VAZ 2107 is simple and reliable. The pressure (drive disk) is installed on the flywheel. Inside the basket there is a driven disk connected to the gearbox input shaft with special splines.

The clutch can be single-disc or multi-disc. The first is considered more reliable. The clutch functions as follows. When you press the pedal, the release bearing mounted on the input shaft pulls the petals of the basket towards the engine block. As a result, the basket and driven disk are disengaged, and it becomes possible to change speeds.

For the VAZ 2107, wheels from the VAZ 2103 (for engines up to 1.5 liters) and VAZ 2121 (for engines up to 1.7 liters) are suitable. Externally they are very similar and have a diameter of 200 mm. These discs can be distinguished by the width of the linings (29 and 35 mm, respectively) and the presence of a 6 mm mark in one of the grooves of the VAZ 2121 damper.

Clutch disc

The driven disc is sometimes called a drum. There are pads glued to it on both sides. To increase elasticity, special slots are made on the disk during the manufacturing process. In addition, the drum is equipped with eight springs located in the plane of the disk. These springs reduce the frequency of torsional vibrations and reduce dynamic loads.

The drum is connected to the gearbox, and the basket is connected to the engine. During movement, they are pressed tightly against each other, rotating in the same direction.

The single-disk scheme used on the VAZ 2107 is distinguished by its reliability, comparative cheapness and ease of maintenance. This clutch is easy to remove and repair.

The driven disk for a 1.5 liter engine has dimensions of 200x140 mm. It can also be installed on a VAZ 2103, 2106. Sometimes a drum from a Niva (VAZ 2121) is installed on a VAZ 2107, differing in size (200x130 mm), a reinforced damper system and a large number of rivets.

Release bearing

The release bearing, being the most vulnerable element of the clutch, turns the rotation gear on and off. It is located in the middle of the disc and is rigidly connected to the pedal through a fork. Each press of the clutch pedal loads the bearing and shortens the bearing's life. Do not press the pedal unnecessarily. A bearing is installed on the gearbox drive shaft guide.

In the clutch kit, the release bearing is designated 2101. A bearing from a VAZ 2121, designed for high loads and having an increased service life, is also suitable. However, in this case, you will also need to replace the basket, since pressing the pedal will require great effort.

Clutch fork

The fork is designed to disengage the clutch when the clutch pedal is pressed. It moves the release bearing and, as a result, the inner edge of the spring.

Most often, if the fork is faulty, it becomes impossible to disengage the clutch. However, sometimes it continues to malfunction. If you do not replace the fork right away, you will have to replace the entire clutch assembly later.

Clutch selection

When purchasing a new clutch kit for the VAZ 2107, experts recommend being guided by the following criteria. When assessing the driven disk:

the surface of the linings must be smooth and uniform, without scoring, cracks or chips;
all rivets on the disk must be the same size and located at an equal distance from each other;
there should be no oil stains on the disc;
there should be no play in the places where the linings and springs are attached;
The manufacturer's logo must be applied to the product in one way or another.

Symptoms of a problem

The need to repair the clutch assembly is determined by the following criteria:

extraneous noise occurs when changing speeds;
the device slips, especially under load;
the clutch does not disengage completely;
rattling;
jerking when starting to move;
The clutch pedal falls out.

If the described signs appear, it is better not to delay repairs in order to avoid unpleasant surprises along the way.

Replacing the VAZ 2107 clutch with your own hands is easy and simple

If the car starts to slip under load, most likely the problem is in the clutch. It is dangerous to move with a faulty unit, so it should be changed as quickly as possible. The article provides detailed instructions on how to replace a VAZ 2107 clutch, which device to choose, and also includes a video demonstrating the process.

When is it necessary to change?

The clutch system allows the car to move off smoothly, removing the load from the engine, which reduces wear on its parts and extends its service life. Overloads are caused by an inertial moment formed during the rotation of parts of the power unit if the crankshaft speed has sharply decreased.

VAZ 2107 assembly diagram

There is no specific time frame for replacing the unit, since the service life of this device mainly depends on operating conditions and the driver’s driving style. It is recommended to diagnose the device after 80 thousand km.

Symptoms of a problem

The need to repair the clutch assembly is determined by the following criteria:

extraneous noise occurs when changing speeds;
the device slips, especially under load;
the clutch does not disengage completely;
rattling;
jerking when starting to move;

Causes of VAZ 2107 clutch failure

Driven and driven discs are subject to the greatest wear.

Clutch failure can be caused by the following reasons:

wear, oiling, defects on the surface of friction linings;
too large gaps or lack thereof in the clutch release drive;
air entering the hydraulic drive system;
fluid leakage from the master cylinder and hydraulic drive system;
loosening rivets;
disc deformation;
jamming, wear of the driven disk hub splines, clutch drive mechanism;
bearing wear;
malfunction of the driven disc damper springs;
breakdown of the release fork or its release spring;
wear of the sealing rings, which impairs the seal.

To eliminate these problems, in each individual case you need to change worn parts; it is better to replace the clutch system assembly.

Visual inspection of the disk

What's the best way to change?

It is best to replace the device by placing the car on a lift, overpass or inspection groove. If this is not possible, then you can raise the car using a jack to get to the unit from below. For safety, you need to fix the wheels so that the car does not roll or put on the hand brake.

Tools

To carry out repairs, you need to prepare the appropriate tools:

set of keys;
screwdrivers;
pliers;
clean rags;
jack;
new consumables.

When choosing a new replacement kit, you need to buy original parts, preferably assembled.

Stages

The replacement procedure consists of the following steps:

Having opened the hood, first of all you need to turn off the power to the car. To do this, you need to remove the negative terminal from the battery.

Engine compartment of VAZ 2107

Then you need to dismantle the air filter housing and unscrew the starter mounting nuts.
Next in the cabin, you should remove the covers from the gearshift knob, floor mats and sound insulation. Then the gearshift lever must be disconnected from the gearbox. To do this, you need to press on it and use a screwdriver to pull out the white plastic sleeve.
To perform further repairs, you need to move under the car.
When removing parts, you should carefully inspect them for wear and defects. Change them if necessary.
At the next stage, we disconnect the exhaust pipe, the working cylinder, the universal joint, from which the wires should be disconnected.
Then we dismantle the starter, which we unscrewed, and remove the gearbox. The gearbox could simply be moved to the side, but it is better to remove it to check the condition of the oil seal. If necessary, the oil seal should be replaced. It is better to remove the gearbox with an assistant, as this is a labor-intensive process. It is advisable to wash the gearbox after removal.
Next, you can remove the basket and clutch disc. In this case, you need to remember how the disk was installed in order to install it correctly when reassembling.

Removing disks from a node
Now you can evaluate the state of the components of the node. The anthers and driven disk are subject to the most wear. The master cylinder and clutch fork should be replaced.
You can only change worn parts, or you can change the entire assembly. It is advisable to replace the clutch assembly, since, having replaced the old parts, there is no guarantee that after a short period of time you will not have to reassemble and disassemble to replace broken parts.

Installing a new drive
Further assembly is carried out in the same order as disassembly.

After the repair is completed, the vehicle system should be checked for functionality.

Cost of clutch assembly

As mentioned above, it is better to change the clutch assembly. The question arises, which device is better.

We can offer four options for assembled units with approximate costs:

Sachs – 4200 rub.;
VazInterService (VIS) – from 2400 rubles;
Valeo – 4200 rub.;
KraftTech – from 2400 rub.

How to replace the clutch on a VAZ 2107?

Every VAZ 2107 car owner, when getting into his car, should always be sure that the car is in full working order. Malfunctions with the clutch will primarily affect the quality of the braking system. If you suddenly notice that the gears have become difficult to switch, in this case it is worth checking the condition of the clutch.

Preparing to replace the clutch
Let's move on to removing the clutch

Preparing to replace the clutch

To replace the clutch, you will need a hole or overpass to get to the engine and gearbox from below. Before all work, you must remove the negative terminal from the battery and you can safely get to work.

First remove the starter and air filter.

Let's move on to the gearbox. The first step is to remove the gear shift lever. There is no need to remove the box itself.

Let's move on to removing the clutch

Let's move on to work “under” the car.

Disconnect the driveshaft from the box.

We unscrew the fastenings of the gearbox safety bracket, as well as the tube from the gearbox. There is no need to disconnect the cardan, since the box does not need to be removed.

Unscrew the nuts that secure the box to the bottom of the car.

Disconnect the wires from the reverse sensor.

Remove the fork spring, which is responsible for disengaging and engaging the clutch, and disconnect the two bolts from the clutch working cylinder.

Remove the clutch pan. Then remove the four clutch housing mounting bolts.

Using a pry bar, push the box as far back as possible. This way she won't get in the way.

Now you will see the flywheel, the basket is secured with six bolts.

Unscrew them and the clutch will be removed along with the release bearing.

Pull out the clutch basket and disc and look at them. If they are in order, then there is no need to change them, or replace them if necessary.

Before starting assembly, it is recommended to lubricate the splines of the gearbox input shaft and polish the clutch disc with a dry cloth.

It is necessary to adjust the location of the clutch disc to the crankshaft bearing. This must be done using a special mandrel. It can be purchased at any auto store. If everything is done correctly, the mandrel will come out freely from the bearing.

That's all, you replaced the clutch yourself, now you can be confident in the reliable operation of your car's clutch.

Order of Operations

For ease of operation, the machine must be placed on a lift, on an inspection hole or on an overpass. If such equipment is not available, you need to jack up the car. To be on the safe side, two. Don't forget about safety and lock the wheels, you can use the hand brake.

On a note! Experts recommend that amateurs take photographs of each stage so that the assembly process after replacing the unit is adequate.

Next, we perform the following steps sequentially:

We de-energize the car by disconnecting the batteries with the minus terminals. Disconnect the speedometer cable from the gearbox, disconnect the clutch cable, and turn off the drive. Experts believe that it is necessary to dismantle the gearbox; this will make it easier to change oil seals, repair the crankcase, and replace the VAZ 2107 clutch slave cylinder. The gearbox has significant weight, and you will need an assistant to remove it. You need to loosen the starter fasteners; to do this, remove the air filter housing and the starter nuts. In the cabin, we completely free access to the gearshift knob, disconnect the knob from the gearbox, to do this you need to pry it off and remove the bushing.

Subsequent work is carried out under the machine. It is necessary to dismantle the driveshaft, exhaust pipe, all electrical wires and the cylinder. We remove the starter, dismantle or move the gearbox. You need to drain the working fluid from the box, you can take the opportunity to change it. We remove the motor support and flywheel, dismantle the clutch using a mandrel. It is advisable to inspect the flywheel for defects and replace it if necessary. We dismantle the clutch basket and disc. We remove the bearing and clean the working shaft of dirt. We install the bearing with the coupling on the clean shaft. If necessary, replace the bearing.

If a leak is detected, repair of the VAZ 2107 clutch master cylinder is required, mainly it consists of replacing the rubber seals. This is a very complex job that requires skills and experience.

Important! When replacing the seals of the working and master cylinders, the brake fluid must be drained, and when performing work, it is not advisable to touch the cone nut, otherwise adjustment will be required.

We install the basket on the flywheel and perform assembly in the reverse order. We carry out the adjustment after replacing the VAZ 2107 clutch with an injector. This model has a special protective cover

In the frontal projection it is fastened with bolts, in the aft projection - with screws. The casing must be dismantled and the length of free movement of the pedal must be checked; it must be at least 1 mm and no more than 3 mm. You need to adjust the size using a lock nut. After realizing the required dimensions, the protective casing is installed in place. Please note! It is important to carry out the actions very carefully so that the pusher does not change its position relative to the GVC.
