Do-it-yourself clutch repair on a classic

In detail: do-it-yourself clutch repair on a classic from a real master for the site my.housecope.com.

It's hard to imagine a car engine without a clutch. The main task of an automobile clutch is to ensure smooth engagement of speeds by briefly disconnecting the engine from the transmission. Thanks to the clutch, the car can move away smoothly without overloading the engine and preventing premature wear of all its parts, as well as gearbox parts. Overloads are caused by the inertial moment, which is formed due to the rotation of engine parts with a sudden sharp deceleration of the crankshaft speed.

Replacing the clutch disc VAZ 2106as well as the clutch basket are usually produced at the same time. This process is not easy and requires certain skills and dexterity, so if you have only recently learned how to change spark plugs on your own, it is better not to risk it and entrust the work to specialists. Replacing the clutch can be done in two ways, with and without removing the gearbox, it is this less laborious and convenient way that we will use today. This work is carried out on a lift or inspection pit.

Secure the vehicle with wheel chocks.
Disconnect the universal joint from the transmission, as well as the clutch slave cylinder.
Remove the reverse light switch wires from the contacts.
Disengage the clutch cover from the side of the cylinder block, unscrew the yoke from the bottom side.
Using the head on "13", unscrew the two retaining nuts that secure the gearbox mount, then remove it.

Move the transmission as far as possible from the engine until the shift lever rests against the rear of the underbody opening.
The transmission will hang from the front exhaust pipe as a safety net, install an extra support under the rear of the box.
Grasp the flywheel assembly, and unscrew the 6 bolts securing the clutch basket using the key "13". Rotate the crankshaft constantly so that you have access to the bolts.

10. Then slide the basket towards the motor and remove the clutch basket.

11. After pulling it out of the clutch housing, remove the clutch yoke and remove the release bearing from the transmission input shaft.

Replacing the clutch VAZ 2106 with your own hands

Clutch parts are installed in reverse order. Before installing them, it is necessary to wipe the working surface of the basket, flywheel, and clutch disc with a clean cloth soaked in gasoline. Center clutch disc in relation to the bearing in the end part of the crankshaft, using a special mandrel that simulates the splined part of the transmission input shaft. When finished tightening the basket mounting bolts to the flywheel, pull the mandrel out, it should come out easily by hand.

Apply a thin layer of “SHRUS-4” grease to the splines of the input shaft, then install the box in place. After replacing the clutch disc VAZ 2106 completed, it is necessary to adjust the stroke of the clutch slave cylinder, it must be free.

Welcome!
The clutch is one of the most important parts of the car, because we use it to change gears. The main work of this unit is to disconnect it from the flywheel while squeezing the clutch and for further switching the box.This unit looks like two discs on top of one of which there is a clutch cover, and the clutch also includes a release bearing with a clutch assembly. But over time, one of the disks or the release bearing itself becomes unusable, which will cause them to need to be changed.

Note!
To replace the clutch, you will need to stock up on: a "13" wrench, and in addition to all this, you will also need to take two different types of screwdrivers (Flat and cruciform in this case), and you also need to stock up on a mandrel for centering the clutch disc, which in a car shop it costs literally 100 rubles! (You can see how this frame, which is mentioned in the article, looks like a little below in the heading: "For beginners!")

Summary:

When should you change your clutch?
During operation, the clutch in any car wears out over time, and the first signs of a worn clutch that the car will give are:

1. Increased noise which very clearly begins to manifest itself when changing gears on the car.

2. And also jerks can occur when starting off in a car, as well as they can occur while driving when you depress the clutch pedal, then turn on the gear and then when you release the pedal, the car jerks forward a little.

Note!
This is mainly due to the damper springs that are installed on the driven disc, and in the photo below they are shown by arrows. These springs are needed so that the clutch disengages smoothly and thus does not give discomfort when driving, and when these springs become unusable, when the clutch is disengaged, as mentioned earlier, a jerk occurs, which often has a very negative effect on the comfort when driving a car!

3. In addition to all this, in the event of a clutch malfunction, the effect of the clutch "slipping" may occur. This is when you drive a car and at the same time squeeze the gas pedal to the floor, and your car does not accelerate, but the engine speed rises sharply and even reaches the red zone, this effect is popularly called the clutch "Slips".

4. Finally, let's note one more effect called the "Leads" clutch. The first signs of this effect are as follows, let's say you engage the first gear and at this time the clutch pedal is still fully depressed, but even in spite of this, the car is rolling. This effect is called the "Leads" clutch.

Note!
Before starting the replacement, be sure to make sure that the clutch malfunction is not caused by any other reasons, because the replacement of this unit itself is very laborious and time-consuming compared to replacing the same clutch slave cylinder due to which it can also be observed the effect of the clutch "Leading"! (If you want to take a closer look at the malfunctions of one or another unit of the entire clutch system, then use the "Search" form, which is located in the upper right corner of the site, and hammer in the search for the malfunction that you exactly need, let's say: "The clutch slips" and you will get all the results in which the given combination of words was found)

Withdrawal:
1) First, to get to the clutch itself, you will need to remove the box for this. (For how to remove the box, see the article titled "Replacing the gearbox with a VAZ")

2) Next, after the box is removed, take the purchased mandrel for centering the clutch disc in your hands, and then install it in the center hole as shown in the photo.

Note!
The mandrel must be installed to the very end, until it rests against the crankshaft bearing!

3) Then, so that the flywheel does not turn, screw one thick bolt, which is indicated under the letter "B", into the lower left side of the block, and then fixing the flywheel from turning "A" with a screwdriver, unscrew all the bolts that secure the casing and the clutch pressure plate itself.

Note!
When unscrewing the bolts securing the casing and the clutch pressure plate itself, hold this disc by its casing so that it does not rotate! (Note that you only need to hold the disc by the casing, because if, for example, you grasp the thrust flange of the pressure spring, you can easily damage it, so only hold the casing with your hands)

4) Next, remove the clutch pressure plate together with the casing, but when removing it, hold it with both hands for its casing.

5) After removing the clutch pressure plate together with its casing, proceed to the removal of the driven disc, for this take the installed disc in your hands and then remove it together with the mandrel from the place where it is installed.

Note!
By the way! If you do not understand where you had to insert the mandrel earlier, then we indicated this place for you with a blue arrow in the photo just above!

Installation:
1) Installation of a new clutch is carried out in the reverse order of removal.

Note!
Install the new clutch carefully and be sure to install the pressure plate, center the position of the drive plate using a mandrel!

For newbies!

Signs of a faulty VAZ clutch can be both difficult switching on of speeds and a problematic start of the car's movement. In this case, it is recommended to replace the clutch disc and, as a rule, the clutch basket VAZ 2107, VAZ 2107 changes at the same time. These VAZ repair operations must be performed either in a pit or on a lift, since most of the work is performed under the car. At many service stations, according to the technology, it is necessary to dismantle the gearbox, but there is an easier way to replace the VAZ 2106 - VAZ 2107 clutch, in which dismantling the gearbox is not needed.

The procedure for performing work when replacing the clutch VAZ 2107, VAZ 2107

The first step is to disconnect the propeller shaft
Then we disconnect the contacts from the reverse sensor
We unscrew the bolts securing the clutch cover on the cylinder head, and also dismantle the underbody cross member.

Video (click to play).

Well, at the end of the preparatory stage, using a head of 13, unscrewing two nuts, remove the gearbox pillow.

Using a pry bar, it is necessary to push the box to the opposite side of the engine, until the gear shift lever is at the rear edge of the hole in the underbody of the car.

As a result, it should turn out that the VAZ transmission unit should lie on the receiving tube, while it is recommended to substitute a stop so that the unit does not slip and sag.

The next step will be to remove the clutch basket from the flywheel of the VAZ engine. To do this, it is necessary to fix the flywheel using the same mount, and then unscrew the bolts 13 fastening the clutch basket VAZ 2107 - VAZ 2107 one by one.

After unscrewing the basket, move the basket aside with a pry bar and carefully remove the clutch disc, as shown in the photo.

Now pushing the clutch basket inward a little, align and pull it out.

Following the basket, dismantle the clutch fork, and replace the release bearing, which is located on the input shaft of the gearbox.

Actually, this is where the removal of the VAZ clutch ends. Now it is necessary to install the new parts in the reverse order and be sure to center the clutch disc relative to the crankshaft bearing. Centering is done with a special mandrel. With the correct position of the clutch disc, the mandrel should freely enter and exit the bearing

And in conclusion, we suggest watching a video of how it happens clutch replacement VAZ (classic)

The clutch is the main component of the 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 until the final stop. In other words, the clutch is a necessary mechanism for 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 clutch release bearing.

So what exactly 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 brake pads, i.e. resistant to abrasion. A spline hub is located in the center of the disc.

As a result of vehicle operation, the clutch disc, like any consumable material, may become unusable - the springs weaken, the friction linings wear out and become thinner. Manufacturers do not indicate a specific lifespan of the disk, since it depends only on the driver: one "traction" can serve only 5000 km, and the other and all 100 thousand. Increased clutch wear can result from:

sharp start-off at high revs;
slipping;
incorrect adjustment;
participation in racing races;
leakage of foreign fluids.

Usually, there are two malfunctions in which it is worth thinking about repairs:

the clutch "slips";
the clutch "leads".

When slipping, the driven disc is not fully pressed against the flywheel. How is this expressed? If you sharply press the accelerator pedal while the car is moving, you can 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 question of replacing the driven disk should not be put on the back burner.

When the clutch is "driving" there are uncharacteristic sounds and noises when changing gears, the gears are difficult to engage. In this case, the driven disk, on the contrary, is not completely "unstuck" with the flywheel. In this case, the pumping of the hydraulics and the adjustment of the free travel of the clutch, which are quite accessible to everyone in the garage, help. Ignoring this malfunction, you can run into an expensive gearbox repair.

Now, in the era of the development of the Internet, there is no need to run around the shops and look for the right 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 range from 470 to 2000 rubles. The cost of replacement work in Moscow and the Moscow region is 2–2.5 thousand rubles.

What can you advise when choosing a disc? Firstly, "rummage" on the forums and read reviews. Secondly, when buying a disc, do not be too lazy to inspect it. Especially carefully study the splines - there should not be any nicks and scoring, otherwise there is a risk that the disc simply will not fit on the shaft or will not be removed the next time it is replaced.

Take a look at the friction linings: they should all be uniform in composition and not have cracks. Another point is the quality of the rivets. The guarantee of quality here is the identity of the flange sizes. Try to swing the damper springs, if there is a backlash, then you should refuse to buy. And the last thing worth paying attention to is the presence of markings on the damper plate.

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

Proceeding to labor exploits, we will carry out the preparatory stage:

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

Now we go 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 gear lever rests against the back of the floor hole. The front of the box will be supported by a muffler, and a secure support must be placed under the rear of the box.
Holding the flywheel with the assembly, unscrew the clutch cover mounting bolts, turning the crankshaft to access them.
We move aside the clutch basket and remove the used driven disc, replacing it with a new one. Before installation, wipe the new disc and flywheel with a cloth soaked in gasoline.
The installed disc 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, remembering to adjust the free travel of the clutch pedal afterwards.Through simple manipulations, you can make a replacement yourself and save a little money from visiting a service station. The main thing is not to miss the moment of disk failure. Not a nail, not a rod!When operating VAZ 2107 cars, car owners invariably need to repair and replace the clutch. On this car, the clutch consists of a release bearing, a disc, a basket, an engagement fork, a slave cylinder and a master cylinder, and other elements. In most cases, it is much easier to replace the clutch using the appropriate repair kits, rather than trying to rebuild individual components.It is about how the replacement of the VAZ 2107 clutch is carried out in this article.It will not be difficult to independently determine the need to replace the clutch with a VAZ 2107. This work must be performed in the following cases:

The appearance of extraneous noise when shifting gears and engaging the clutch.

Jerks appear at the beginning of the movement and starting off.

Wheels can slip under load.

The clutch pedal starts to fall.

In case of significant breakdowns, pressing the corresponding pedal does not engage the clutch, which does not allow changing gear.

It should be said that you should not delay the repair in the presence of such symptoms, since a broken clutch will invariably "pull" the gearbox and other expensive components along with it, and such repairs will have a high cost.
There may be several reasons why replacement of the VAZ 2107 clutch slave cylinder is required. This is an aggressive driving style, when such units have an increased load, and the use of low-quality spare parts. It is recommended to carry out such repair work every 50-60 thousand kilometers of the vehicle's run. By this time, most of the clutch assemblies have increased wear, which will require diagnostics and replacement of this assembly.To perform such a clutch replacement, you will need:

Jack

Pliers

Screwdriver

Key set

Dismantling tool for clutch basket

Rags

We recommend purchasing original clutch repair kits for the VAZ 2107, which will allow you to completely restore the damaged unit. It is also possible to repair and replace clutch elements separately, but this leads to a certain complication of such work, so most car owners still choose the appropriate repair kits, and easily replace the clutch. Let's talk in more detail about how to change the clutch on the VAZ 2107.This completes the replacement of the VAZ 2107 clutch. Despite the seeming complexity, any car owner can handle them, while you can save a lot, since the prices for such work in service workshops are quite high today, and by performing all the repairs yourself,you will not lose at all in its quality ! !

Do-it-yourself clutch replacement for the first time should only be done with an assistant. Car repairs must be carried out on an overpass or using a lift, as well as using special tools.

When replacing the clutch, you must first dismantle the propeller shaft, starter, gearbox, etc. Next, you need to block the flywheel with a screwdriver and unscrew the six bolts with which the casing is coupled to the flywheel. Next, you need to remove the casing together with the driven disc.

If the slave disk has any problems, then it is necessary to replace it. In this video about clutch repair, you can look at all the problems that require the replacement of this part. Next, you need to inspect the flywheel, which should not be scored, deep scratches, signs of wear, overheating. Otherwise, this part must be replaced with a new one. When disconnecting the gearbox from the motor, it must be secured so that it does not fall. Replacing the clutch fork is done in this way: removing the gearbox, removing the ends of the spring from the clutch paws of the bearing, removing the guide sleeve. After that, the clutch fork is removed, which is replaced.

When replacing the cable, you must remove it by disconnecting it near the release lever and removing the stopper tube from the pedal finger. Next, the rubber cushion is removed in the shield hole, and the clutch cable tip is also removed, which must be replaced. The clutch has a fairly simple structure, which allows you to replace and repair it yourself.

The procedure for replacing, repairing and bleeding a VAZ 2106 clutch with your own hands is quite easy to perform if you follow all the tips that are given in the next video.

This pelvis pleases the Eye :), but it is necessary to change the clutch and the input shaft oil seal, as well as the backstage gasket and change the oil.it was not necessary to squeak a small mate. Why unnecessary editing 🙂You never know we will be shown on TV)))))))))))))) Joke). There are people who are very disgusted with obscenities, but those who are not disgusted will understand everything 🙂Not bad) How much real time was spent? From disassembly to assemblyI bought the same syringe. I wanted to fill in the nine in the yard without a hole. All the oil on the face turned out to be))))))))) I had to go through a funnel and a hose .. a box without a dipstick .. old)We were probably lucky and the oil only got on our hands)) The syringe is really very poor.I seem to be more than 1.5 in the sevenWe poured exactly 3 syringes of 0.5 l each through the filler neck, and through what did you pour? Is it possible that you were pouring through the wings?guys, take off how to adjust the valves on the classics)If you turn up a car with unregulated valves, then be sure to take it off. 🙂The oil seal is much easier to remove. If you look into the bell from the engine side, then in the area of the oil seal there is a hole in the release bearing guide through which the oil seal is easily knocked out. And yet, in vain they turned over the spring washer between the checkpoint and the bell. If it is standing correctly (with a large diameter of the cone towards the bell), then it is centered on the walls of the bell and will never move anywhere. Its role is to squeeze the input shaft from axial movement to fully engage the 4th gear.The 5-speed gearbox on the classic is made a little not well thought out, when you fill in oil at the level, the 5th gear is starving and then it just dies ((((you need to tilt the car and fill in about 1.7 litersOperation of the vehicle without the participation of the clutch unit is impossible, because this mechanism is the link between the vehicle's power plant and its transmission. Without it, it is not possible to comply with the mode of short-term shutdown of the gearbox mechanisms, which are simply necessary when organizing the process of movement of the "six", and all motor mechanisms.Often, Russian motorists ask how to change the VAZ 2106 clutch on their own, without involving the forces and funds of the repair authorities. In this case, you need to know that sometimes replacement is required due to the wear of individual components and mechanisms of this unit. This type of clutch repair can be carried out as a whole or in individual components.For example, replacing a clutch disc of a VAZ 2106 of a driven type, as well as a driving disc, is usually carried out in one step. Technological operations of this type are considered quite complex, requiring special skills and a certain skill. In the absence of repair practice and poor knowledge of the "six" device, it is better to drive the car into a service and carry out the necessary work there. Such a clutch replacement is carried out in 2 options:

with the removal of the manual transmission;

without dismantling the gearbox.

Similarly, without removing the manual transmission, the VAZ 2106 clutch fork is replaced, although such repair operations in the workshop of the service station are carried out with the removal of these transmission elements. If you remove the clutch in full, it will take a long time. If these repair operations are carried out at a specialized passenger car service station or at a regular VAZ service center, then it will be quite expensive.To replace the VAZ 2106 clutch, it is necessary to have certain skills for the production of locksmith work and to have on hand the necessary set of tools and a new product to be replaced. Consider the procedure for removing the clutch without dismantling the manual transmission, which is carried out in compliance with the following repair operations:On the Internet you can watch the video "replacing the VAZ 2106 clutch", which clearly shows the sequence of operations.Such a replacement of the main-purpose clutch cylinder is carried out in the following order:1. We install the vehicle on a car inspection pit, overpass or electric lift.
2. With a special bulb made of rubber alloys or a similar product, we take the brake fluid from the hydraulic reservoir of the clutch drive.
3. Slightly unscrew the rubber clamp fastening the expander tank for the antifreeze content and move the product onto the plane of the power plant.
4. Unscrew the metal tube with a wrench to "13", disconnect it from the inlet channel of the GCC and move it for the convenience of repair work.
5. Unscrew the metal band-type clamp a little and tighten the GCC union hose.
6. Using a socket-type wrench on "13" with a knob, unscrew 2 fasteners of the GCS and release it from the fasteners.
7. We install the repaired or new GCC and all previously unscrewed parts in the reverse order.
8. Pour the "brake" into the clutch hydraulic reservoir to the required amount and bleed the clutch on the vehicle.When all these stages of the technological process are completed, the replacement of the VAZ 2106 clutch cylinder is considered complete. Image - Do-it-yourself clutch repair on a classic

There are several types of clutches: hydraulic, mechanical and combined. On Russian VAZ cars, only a mechanical and hydraulic drive is used. The process of adjusting the clutch itself depends on its type. In the process of work, a set of keys and a ruler will come in handy. In order to make sure that the clutch really needs to be adjusted, you need to measure the distance between the lower and upper points of the clutch pedal travel, it should be between 120-130 mm.

During machine operation, the clutch disc friction linings gradually wear out. At the same time, the free travel of the clutch pedal increases from the top to the bottom. The biggest deviation from the norm is considered to be 30 mm, which means that the free travel of the VAZ clutch pedal should not exceed 160 mm.So, take a ruler and apply it to the pedal so that one of the ends of the ruler rests perpendicularly on the floor mat. Next, we need to calculate the distance from the mat to the top edge of the clutch pedal rubber pad. Now we know the stroke length and if it is more than 160 mm, then we need to open the hood and find the clutch cable in the engine compartment. As a rule, it is located on the right side of the motor, between the wall and the wheel arch. After we have found the cable, we need to loosen its fastening and adjust the lock nut. We set the clutch so that the full stroke from top to bottom has a distance of 120 mm. Then we tighten the control nut into place. We get into the car and again fully squeeze the clutch cable three times. Using a ruler, check the full pedal travel again. If necessary, repeat the process one more time until we get the recommended values.

A properly adjusted VAZ 2107 clutch ensures the normal operation of the car and the long-term operation of units and parts of the car. It is recommended to check the correctness of the adjustment every time the vehicle is serviced.

During operation, incorrect adjustment can be expressed in two types of malfunctions:

The clutch slips - when the pedal is fully released, the disc slips and does not transfer the power of the engine to the transmission in full;
Clutch leads - when the pedal is fully depressed, the disc does not move away from the flywheel, which prevents normal gear changes and forces the machine to move when it is not needed.

In addition, the clutch may engage too early or late, making it difficult to control the vehicle.

The adjustment process itself consists of two parts. The first is performed in the cabin, the second - under the bottom of a VAZ 2107 car, from an inspection pit. Of the tools you will need:

Key for 8 or 10, depending on the model of the clutch slave cylinder;
Open-end wrench for 13;
Open-end wrench for 17.

The first adjustment involves setting the clutch pedal travel. It is performed from the passenger compartment, under the steering column. To limit the full stroke, a special adjusting screw is used, fixed with a lock nut. Twisting or unscrewing it, we achieve the normal pedal travel, which should be approximately 140 mm. There is usually no need to adjust the full stroke, it is installed from the factory and changes very rarely.

The second part of the adjustment is to set the pedal free play. In normal mode, it should be 30-35 mm. However, some motorists adjust the free wheel to their individual habits and preferences. This approach is quite acceptable, provided that it does not affect the performance and durability of parts of the VAZ 2107 car.

So, to check and adjust, we go down into the inspection pit. The clearance is checked by pulling the fork away from the pusher.

The free play distance should be 4-5 mm. If the gap differs significantly from the standard, it must be adjusted. For this:

Remove the spring pulling the clutch fork to its original position;
We release the lock nut on the pusher;

Holding the pusher with an 8 (10) wrench, screw or twist the thrust nut until the required clearance is reached;

We fix the thrust nut with a lock nut;
Checking the gap;
We install the spring in place.

This completes the adjustment procedure. However, in order to be sure of the correctness of the result obtained, it is necessary to test the adhesion in action. To do this, we start the car, turn on the gear and smoothly begin to release the pedal. With the correct adjustment, the vehicle should start at about half the pedal travel. Adjustment is allowed, turning on the clutch below or above, but it is unacceptable to switch on at the very top or bottom, since there is a risk of the above malfunctions.

Today, the article will talk about procedures such as replacing and adjusting the clutch 2106 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 cannot be. Often, drivers try to solve all problems with the car on their own, because the cost of maintenance is absurdly high.Even despite the fact that the VAZ 2106 car has not been produced for ten years. And we will try to help as much as possible in the repair. If you have any questions, leave comments, share our experience, describe unusual situations. After all, the topic is quite interesting and rich.You all know that there is a clutch pedal at the driver's feet. For some, this is enough, they do not go deeper further. But if you have already decided to take up the repair, you will have to study the rest of the chain. On a VAZ 2106 car, as in the rest of the classics, the clutch drive is hydraulic. From the pedal, the master cylinder rod is set in motion, which moves the small piston in itself.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 machines, 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, let the brake fluid pass.The clutch can fail for several reasons:

Resource development.

The presence of a factory defect.

Tough exploitation.

Mechanical damage during operation.

Very often, the reason for the premature failure of the clutch elements of the VAZ 2106 is the presence of a factory defect and increased loads. In particular, traffic jams in the city make themselves felt pretty soon.Depending on the type of breakdown, the following symptoms may appear:

The clutch pedal falls through, the engine and gearbox shafts do not open.

The clutch works, but there is an extraneous sound.

The engine picks up speed, but the speed does not increase - the clutch slips.

Gear shifting is difficult, the clutch "leads" - it is not turned off completely.

The appearance of a leak from the expansion tank, pipes, cylinders.

The fact that the master cylinder is mechanically connected to the pedal has already been said. But the clutch fork and the slave cylinder are mounted directly on the gearbox. With the help of these mechanisms, the release bearing is moved along the axis of the input shaft.The principle of operation of the entire clutch drive mechanism on a VAZ 2106 car is as follows:

The driver presses the pedal.

There is a movement of the rod and with it the piston in the cylinder.

The pressure builds up in the pipeline between the master and working cylinders.

Due to the increased pressure in the working cylinder, the piston and the rod move, which drives the clutch fork.

After all this, the clutch disc of the VAZ 2106 and the basket move away from each other, the crankshaft does not rotate the primary. Consequently, the vehicle is not moving. And now about the repair procedure.Before you put the car in the pit and remove the box to replace the clutch, you need to go to the store and buy all the necessary parts:

Clutch disc.

Recycle bin (master drive).

Release bearing.

If necessary, the clutch fork.

If there is a significant development, it will be necessary to replace the crown on the flywheel.

Flywheel to basket mounting bolts.

It is also important to have a good set of tools on hand, penetrating WD-40 grease, sometimes even a gas burner is necessary (if the bolts and nuts are very rusty).It is advisable to carry out all the work on the inspection pit or overpass (it is unlikely that the average driver of the six has a lift in the garage, so we do not mention it).If everything goes smoothly and the nuts loosen well, you will get the job done very quickly.Place the car in the pit, fix it in one position by placing stops under the wheels. All work is divided into two stages: under the machine and above it. Please note that there is no need to drain the oil, since if it is carefully dismantled, you will not spill a drop.And don't forget to center the clutch disc. The price of a special device is quite high - about 500 rubles. but it is possible to use a small piece of pipe without problems, as long as the diameter is suitable.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 observe a certain sequence:

In the car, remove the gearshift knob. It is secured with plastic clips. Sometimes difficulties arise with dismantling, it comes to the point that the latches break off. The price of a new set of mounts is no more than one hundred rubles, and you can buy it even after repairs. Therefore, do not be afraid if the plastic antennae are suddenly broken.

Go to the engine compartment, unscrew the four nuts that secure the front pipe to the manifold. The fact is that the front pipe will interfere with the removal of the box, but it is enough to move it slightly to the side.

Disconnect the battery and remove it from the vehicle.

Unscrew the two upper bolts of the starter, disconnect the power wires of the windings and the solenoid relay from it.

Disconnect the ground wire that fits the gearbox.

Look carefully to see if there are any "upgrades" specifically on your car that will interfere with the removal of the gearbox. If so, make sure that they do not complicate further repairs.Perhaps this is the most difficult part of the entire repair, since there are many more steps to be taken. So make yourself comfortable and proceed with the following operations:

Unscrew the last (lower) starter nut and remove it. This nut is the most disgusting, since it is problematic to get to it with simple keys, you will need to use a head, a ratchet and a universal joint. True, it turned out to work with an ordinary open-end wrench installed in the end.

Unscrew the outboard bearing bracket.

Disconnect the propeller shaft and rear axle flange. Hold the head of the bolt from turning with a 12 mm open-end wrench.

Hit the propeller shaft hard to knock it off the rubber coupling on the transmission shaft. Move the gimbal to the side.

Unscrew the pillow mount, install a support under the checkpoint.

Remove the slave cylinder from the clutch fork. Do not lose the bar that is under it and the spring.

Remove the speedometer cable.

That's all, now it only remains to unscrew the four bolts that secure the box to the engine block.

Remove the gearbox carefully, try to move it away from the engine block as far as possible. The fact is that you can damage the VAZ 2106 clutch drive disc. And it is quite simple to do this.If we take nines and newer VAZs as an example, then the clutch discs on them are more reliable and durable. It is advisable to set the gearshift lever to the position corresponding to the third speed.Please note that it is imperative to install new clutch basket mounting bolts. On old ones, the threads already have small deformations, therefore, the connection will be very unreliable. The price of all elements will be approximately 2000-2500 rubles.I decided to get a job in a taxi. I reviewed many proposals, but did not find anything good. Then a friend advised me to rent a car for a taxi and get to work! I've been working for six months now and I'm very happy!If you prefer foreign-made units, then it will be more expensive. However, it is worth asking a simple truth: the service life of an imported one is sometimes less than that of a domestic one, and the price can be twice as much. 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 back to the replacement procedure. Unscrew all the bolts from the basket, remove it and the clutch disc. Install new elements in the same way, but screw the bolts, do not tighten. It is advisable to look at the condition of the crown before installing. If it is deplorable, then you should immediately put a new one.In stores, its price is about 200-250 rubles, not very expensive. But you can reduce the cost of repairs, it is enough to remove the crown, heat it up and install it with the reverse side. But you will have to buy a new one if such a procedure was previously performed.Pay attention to the VAZ 2106 clutch fork, if it is damaged, be sure to replace it. A new throwout bearing is fitted in any case. You can apply CV joint grease to it, for example. This can slightly increase its resource.Almost finished, it remains to take the guide sleeve and install it in the hole in 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, its resource will decrease.That's all, the clutch replacement was successful, now it remains to assemble the car. But here no difficulties will arise, since all actions are reversed to those that were described in detail in this article. If you also need to change the brake fluid in the drive system, then read on.It is very simple to drain the fluid from the clutch drive system:

Pump out liquid from the expansion tank with a blower.

Unscrew the union on the working cylinder and wait until all the liquid has left.

Press the clutch pedal several times to dispose of the remaining brake fluid.

Change tubes as needed.

Screw on the union.

Fill the reservoir with fresh brake fluid.

Slide the transparent tube over the fitting.

Ask an assistant to press the clutch pedal several times. The last time you press it, you need to hold it in the extreme position.

Unscrew the fitting half a turn, allowing the liquid and air to escape.

Repeat the procedure until the liquid begins to flow without air bubbles. Remember to keep an eye on the level in the expansion tank.

In fact, two or three passes are enough to get rid of the air in the system. As you understand, pumping the clutch on a VAZ 2106 is easy. The procedure is very similar to bleeding the brakes, only it is performed much faster - the line is very short.After replacing the clutch, you will need to adjust it. Pay attention to the rod of the working cylinder - 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 travel of the clutch pedal, for this a special bolt is provided directly above it.
