How to independently replace the clutch on a VAZ 2109?

In what cases is it necessary to adjust the clutch pedal?

Adjusting the VAZ 2109 clutch is necessary because:

• If the clutch pedal is adjusted incorrectly, the car spends too much energy moving and repairs are inevitable during further use.
• When the pedal stroke is small, the car's torque is lost. As all car enthusiasts say, the clutch slips.
• If the pedal is adjusted incorrectly, the flywheel comes into contact with the clutch disc and wear occurs.

Step-by-step instructions for adjusting the clutch on a VAZ 2109 with your own hands.

In order to correctly configure (adjust the clutch) on a VAZ 2109 car, you must perform the following steps:

1. Pull the handbrake and turn off the power to the car - for safety.
2. In the engine compartment below, find the metal clutch cable. In the photo there are 3 red arrows pointing to it.

   

3. Using 2 wrenches, loosen the cable end mounting nuts, and then, tightening or loosening them, until the clutch pedal travel becomes 125-135 mm.

4. Get back into the car and press the adjustable pedal all the way down several times (at least 3 times). Then measure its progress again and adjust if necessary. If no adjustments are needed, then you did everything right.

If the nuts you are going to work with are rusty and therefore cannot be unscrewed, treat them with VD, machine oil or any other lubricant. This will save your energy and time.

VAZ clutch diagnostics.

You can determine whether the clutch pedal is adjusted correctly or not independently, without the intervention of a car service center. You only need to adjust the pedal stroke if you have any signs of a problem.

How to independently determine whether the clutch pedal is adjusted correctly:

• When the car starts moving smoothly, it jerks, hits and makes noise.
• The pedal fails.
• When the speed is turned on, a noise is heard.
• If the car starts to move immediately after you start releasing the clutch pedal.
• If the car does not move at all even after fully releasing the pedal.

The VAZ 2109 clutch is slipping - what to do?

Clutch VAZ 2109

Usually the VAZ 2109 clutch slips due to deterioration of the vehicle’s traction capabilities. This can also lead to a decrease in speed and difficulty driving on difficult roads. If the clutch on a VAZ 2109 is slipping, you should urgently repair it.

What causes the clutch to slip?

The most well-known causes of car slipping:

• the pedal does not move freely;
• friction linings are worn out;
• rubber parts are swollen.

In order to eliminate or prevent clutch slipping, you first need to check the clutch pedal travel. If necessary, it is adjusted.

Friction linings worn down to rivets

VAZ 2109 clutch slips

The reasons for this problem may be:

• normal wear taking into account operating conditions;
• errors when driving a car, pressing the gas pedal from a standstill;
• poor clutch system movement;
• Incorrect installation or adjustment of the clutch drive.

Note! In such a case, the clutch is compressed with insufficient force.

The elasticity of the pressure plates is lost

VAZ 2109 clutch slips

Clutch disc slipping can occur when the pressure springs are weakened or faulty. This can also occur due to wear or warping of the friction surfaces of the flywheel with the pressure disk.

Note! If the friction linings of the driven disk are oily, then they, along with the faulty pressure plates, are replaced with new ones.

The rubbing surfaces of the flywheel with the pressure disk are processed using grinding. If, when moving the car, there is a smell of burning linings, there is slight acceleration, a decrease in speed, or a slow crossing of hills, then the reason is most likely hidden in the clutch; it may not be fully activated. If the engine turns off, the clutch will work normally, but if this does not happen, then we can conclude that the clutch is slipping.

VAZ 2109 clutch slips

In the best case, it is also recommended to replace friction linings when cracks, burns and scuffs are detected on the surface. Clutch slippage can sometimes occur due to swelling of the rubber elements of the hydraulic drive. Such a defect most often occurs due to the use of low-quality brake fluid, or the composition does not meet the standards. Penetration of mineral oils, kerosene or gasoline into the liquid is not excluded. To fix this problem you need to:

• dismantle the functioning and main hydraulic drive;
• disassemble the system;
• rinse it with purified brake fluid;
• replace swollen parts;
• clean the expansion hole;
• Fill with clean, high-quality liquid.

The elasticity of the pressure plates may disappear due to long-term operation. This can also happen due to insufficient pressure on the disk (driven). It is recommended to check the condition of the plates at a car repair shop, since it is impossible to do without the use of special instruments and devices.

As a rule, weakened springs need to be replaced. This also applies to friction lining oil.

Oily or greasy friction linings

This problem can happen for several reasons:

• if the gearbox or engine seal is damaged;
• in case of excess lubricant on the gearbox shaft or on the crankshaft;
• if the seal of the hydraulic drive is broken.

Note! As a result, the friction coefficient of the linings is reduced.

If, during normal movement of the pedal, the clutch still slips, then, most likely, oil has got on the linings. It is necessary to dismantle the clutch and check the driven disc with linings for oiling. Typically, oil penetrates the disc and linings due to its excess in the gearbox, as well as due to contamination of the flywheel drainage gap. To remove oil from the pads, they need to be washed thoroughly with kerosene or gasoline. After this, the parts are wiped dry and cleaned with sandpaper.

If the driven disk is very oily, it must be changed; this also applies to the set of friction linings. Next, you need to set the gearbox to a normal oil level and clean the flywheel clearance.

Friction lining burning or peeling

Clutch slips in VAZ 2109

Burning or peeling can happen due to:

• frequent clutch slipping;
• "acceleration" from a standstill in high gear;
• excessively low clutch squeezing force;
• malfunctions or defects in the clutch activation system or due to the lack of clearance that should form between the clutch release lever and the bearing;
• oiling and salting;
• excessive flywheel depth, this may be a tuning error.

Note! In these cases, overheating can occur, leading to significant damage to the pads.

Friction linings do not absorb the load over their entire surface

The reasons for this feature include:

• flywheel malfunction;
• presence of scratches on the friction surface.

As a result, the friction coefficient of the linings may decrease.

Note! The friction lining on the new disk first takes up the external load, while ensuring the full load of the replaced parts is ensured before general development.

Pressure plate overheating

Overheating can occur for several reasons:

• due to frequent clutch slipping;
• when salted or oily;
• due to a breakdown or defect of the clutch or due to a small gap between the clutch release lever and the clutch bearing;
• if the flywheel depth is significantly greater than normal.

If one of the reasons is present, the friction coefficient of the linings may decrease. Constant slipping affects the increase in heat absorption capacity. The result is overheating.

Severe wear on the diaphragm spring limbs

Clutch

This can happen in cases where:

• the drive system wears out;
• the guide tube has worn out;
• The bearing is subject to too much load.

The effectiveness of the clutch squeezing force is blocked due to freezing of the release bearing, and it can also be partially reduced due to a high initial load.

Broken diaphragm spring

Vase pressure disk

Fracture of the element can occur due to high compression forces or the permitted clutch disengagement stroke. In such a situation, the spring may lose its own design parameters.

Note! The clutch may disengage when the pressure plate is pressed slightly.

If possible, the problem with slipping should be solved immediately, as soon as the first causes are discovered. Otherwise, when driving on difficult roads, there will be a risk of engine failure. If you cannot identify the cause of the car slipping yourself, you need to contact a car service. If the cause is still identified through video and photos, you can try to fix the problem yourself.

For easy work on the network, there are instructions for repairing a particular element. Since the price of services at service stations is constantly growing, many people prefer to repair their car themselves.

Design and adjustment of the VAZ 2109 clutch

VAZ 2109 is the legendary “nine”. The front-wheel drive five-door hatchback was serially produced at the Volzhsky Automobile Plant from 1987 to 2004. From 2004 to the end of 2011, the VAZ 21093 modification was assembled in Zaporozhye.

Many car owners try to maintain their personal car themselves and know how to do it correctly, since they carefully study the operation of the main components and leading modules. The list of routine maintenance includes periodic adjustment of the VAZ 2109 clutch. This task is quite simple if you familiarize yourself with the operation algorithm in advance.

Nine clutch device

The clutch kit is one of the key components of the Nine transmission. This is a single-disc friction-type mechanism located between the engine and the gearbox (gearbox). The algorithm for its operation is as follows:

1. Initially, the car is stationary, the engine is started, the pedal is released. The gearshift lever is in the neutral position, that is, the rotation of the input shaft is not transmitted to the secondary shaft.
2. The driver is preparing to move forward. With his left foot he presses the pedal, and the mechanism disconnects the gearbox input shaft from the engine. The driver moves the lever to the first gear position, the mechanism ensures the engagement of the primary and secondary shafts of the gearbox. The car is stationary because the engine is disconnected from the transmission input shaft.
3. The driver smoothly but decisively releases the pedal. The engine is connected to the input shaft, the task of which is to transmit power to the drive wheels through the secondary shaft, then the car will start moving.
4. Switching from first gear to second, from second to third, and so on occurs in the same way.

The VAZ 2109 clutch design is such that when the pedal is released, the driven disk is clamped by springs between the flywheel and the pressure plate. In this case, power is transferred to both gearbox shafts and the drive wheels. When you press the pedal, the VAZ 2109 clutch fork rotates through a special rod and presses on the levers that retract the pressure plate. The VAZ 2109 clutch driven disc is disconnected and power transmission stops. The mechanism casing is connected to the pressure plate by three pairs of elastic plates. The unit is driven by a cable, its lower tip is fixed with nuts in a bracket on the engine crankcase.

The clutch cable is connected to the clutch release fork lever.

Do-it-yourself clutch adjustment

Experienced car owners know how to adjust the clutch on a VAZ 2109 on their own. Indeed, there is nothing complicated about it. Two 17mm wrenches and a regular drawing ruler 30cm long are all you need for the job. There is no need to open the VAZ 2109 clutch housing; the work is feasible even for an inexperienced vehicle owner.

Motorists usually check the adjustment approximately every 15 thousand kilometers or once a year. If there is a feeling of increased pedal travel, prompt inspection and adjustment are carried out. Work should be carried out in the following order:

1. Take a mechanic's ruler or a drawing ruler and measure the distance from the pedal in a free state to the floor of the car. Usually this value is about 20 cm. This will be the first size.
2. Press the pedal with your hand and push it all the way down. Measure the distance from the pressed pedal to the floor. This is the second size.
3. Calculate the difference between the second and first dimensions and you will get the pedal stroke. If the result is 125-135 mm, clutch pedal adjustment is not required. When the calculated number does not fall within the specified range, adjustment is advisable. But if the pedal travel is 160 millimeters or more, the mechanism must be adjusted immediately.
4. To adjust the pedal travel, open the hood, turn off the power to the electrical system, and put the car in the parking brake and in first gear.
5. Hold the adjusting nut with one wrench and loosen the locknut with the second. The adjusting nut is located in the engine compartment of the VAZ 2109 on the drive bracket mounted on the gearbox housing. The nut secures the drive shell in this bracket, and the locknut protects it from loosening.
6. To decrease the pedal stroke, the cable must be tightened; in this case, rotate the adjusting nut counterclockwise, and to increase the stroke, clockwise.
7. Achieve the desired pedal stroke and secure the new position with the lock nut.

This completes the adjustment. Pump the pedal several times and make sure the travel is within the normal range. If it exceeds the acceptable limits, repeat the adjustment process.

Adjustment can be carried out in the warm season and even in the absence of a garage.

• When you press the pedal for a long time, the clutch begins to slip.
• Vibration and crackling is felt when pressing the pedal.

The clutch is adjusted in the following order:

1. Leave the car in neutral.
2. Unscrew the clutch housing.
3. Remove the bearing. This should be done carefully so as not to damage it.
4. Adjust the nuts until the pedal travel returns to normal.

The design of the VAZ 2109 friction clutch and its purpose

Any self-respecting motorist will study the design of the unit before adjusting the clutch on a VAZ 2109. This will help you approach the issue wisely and avoid mistakes.

In the photo: The process of tightening the clutch cable on a VAZ 2109 car The design using a mechanical drive is simple and reliable. Compared to hydraulics, the cable requires minimal maintenance, and changing it is not labor-intensive. The mechanical drive consists of the following elements:

• Adjustable sheathed cable.
• Control pedal.
• Clutch release fork lever.
• Bracket for fastening the end of the cable sheath.
• Brake and clutch pedal bracket.

The mechanism serves to transmit force from the pedal to the release fork, which, in turn, removes the friction disc from the flywheel. Using a cable drive avoids major problems such as fluid leaks and periodic bleeding of air from the clutch control system. The weakest link in this chain is the cable, the quality of which at times leaves much to be desired. Therefore, replacing a cable on a Samara is a fairly common occurrence.

Meanwhile, the question of how to adjust the clutch on a VAZ 2109 car remains relevant for the cable mechanism. Setting standard values ​​guarantees optimal tightness of the driven disk to the plane of the flywheel and basket when the clutch is engaged. The design also ensures complete separation (switching off) of the above parts from the passenger compartment through the pedal.

Replacing the clutch cable without removing the frill

Replace clutch cable VAZ 2109

Replacing the cable without removing the frill is much easier than replacing it, since the second option involves many unnecessary manipulations. To easily replace it at home, you need to:

• ​Unscrew the cable fastening using a 19 mm wrench.
• Remove the cable end from the clutch fork.

Note: Sometimes this action is unnecessary. It depends on the location where the cable was torn.

In the cabin, under the pedal, you need to find the cable fastening nut. It is very small, so to remove it you will need an 8 key.

VAZ 2109 clutch cable adjustment

• Unhook the bracket that secures the cable end to the clutch pedal. To carry out this action, you should raise the clutch pedal as high as possible, and then use a screwdriver to hook the clip.
• Pull out the clutch cable. You don't need to tug on it too hard. The point is not that it will tear, it is already torn. You can simply damage the “nest” in which it was located. You need to pull it out directly through the interior.

Note: there may be extra wires in the cable channel that will make it difficult to remove the cable. You can safely tear them out, as they do not provide any benefit. Washers under the hood may also be in the way. In this case, they need to be carefully unscrewed.

• Remove the bracket located on the pedal arm. This will make it easier to remove the cable.
• Slowly insert the new cable into the hole through the interior and into the hood.

VAZ 2109 clutch cable

You need to fasten everything in the reverse order.

Note: the most difficult part will be to put the tip mounting bracket back in its original place. It's not that easy to get there. This is why many people take off their frills.

• However, the mounting bracket can be returned to its place in another way. You should make a clip from a regular paper clip. With its help you need to secure this bracket. If necessary, you can use pliers.
• It is advisable to lubricate the cable with oil or grease at the end (it does not freeze in winter) to make it more elastic.
