On all cars produced by the Russian automaker AvtoVAZ, including the most popular model in our country, the Lada Priora, the clutch is activated thanks to a mechanism called a clutch cable. This special mechanism is very important in the car control system and is sometimes called a clutch. Those car owners who prefer to carry out replacements and repairs in the car in a timely manner and with their own hands will be interested in studying this material, in which we will tell you about this device and how the clutch cable is replaced and other nuances.
About working on the clutch cable on LADA Priora
Initially, on domestic passenger VAZs with a rear-wheel drive system, the clutch was engaged thanks to an ordinary hydraulic system. The principle is exactly the same as that of the brake drive: all the pressure from the main cylinder is supplied to the so-called working cylinder. Only modern cars, such as, for example, the Lada Priora we are considering, received a front-wheel drive system; the specialists of the automobile manufacturer abandoned this principle of operation of the device in question, which greatly facilitated maintenance. The company has developed a reliable and very simple system for engaging a car clutch using a cable, now it is the main one in the entire system. The principle of the rocker arm, so to speak, is applied here, that is, when pressing the lower part of the corresponding pedal while sitting in the car, its working part, located at the top, passing through the rod (the so-called base), certainly begins to go in a completely different direction, plus everything else at this time she pulls the cable straight and, of course, behind her.
The second end of the cable is located on the drive fork of the clutch system. When the pedal is pressed, the clutch is released, thus directly enabling shift/on. transfer.
Priora clutch: price, manufacturers, adjustment, replacement
› Transmission
A caring attitude towards the clutch is instilled in driving school. Gently pressed, switched gears, gently released. The clutch is the unit connecting the gearbox and the motor. Adjustment is needed after replacement. As a rule, clutch replacement can be done in a garage. Lada Priora is generally a repairable car. At a service station, work will cost 1500-2000 rubles.
The price of a set of original clutch costs approximately 2000 rubles. On foreign cars the price of the unit is more expensive even with replacement and adjustment. With the purchase of your first car, your understanding of the full value of the clutch increases significantly.
On the Priora - one of the most popular city cars - many learned to drive (for real, without an instructor!) and perhaps changed the unit in the garage.
The Priora clutch is simple in design, but, nevertheless, it must always be in good working order - the health of the car and traffic safety depend on it. Therefore, you need to know everything about replacing a unit on a Lada Priora - after all, it’s not just a clutch pedal, it’s a whole mechanism. Which is involved in setting the car in motion - the gearbox and the engine are on friendly terms.
As an example, everyone understands that to disengage the clutch the pedal must be depressed. What happens if the machine does not respond to this? Will it bite or stall in the middle of the road? You shouldn’t listen to advice at all, trying to torture the gearbox without a clutch, “catch” the speed. There is only one way out of this situation: learn a good lesson and worry about the “health” of your “friend” in time. Read the article to the end and you will be safe - this unit will definitely not let you down on the road!
Clutch cable device in Priora
In order for the drive to work properly and stably, the core (cable) is located inside a special casing, completely fixedly fixed. As mentioned above, one end of the cable is attached to the clutch fork, as you understand, on the gearbox, and the other end is located in the cabin near the pedal. Each end is equipped with a fastening device. The ends are very different from each other, and it is simply impossible to confuse them in any way. There is also a rubber coupling; it is installed in the body in the hole where the cable goes into the compartment where the engine is located from the car interior.
So, the device consists of the following elements:
- In duplicate, fasteners for the casing.
- Clutch cable.
- Fastening element for fork.
- There is a special loop for the pedal.
- Rubber casing to protect the interior opening.
As you already understand, the core is located inside a hard shell, where it moves under the influence of return springs and the pedal itself. Thanks to this, its stable operation is ensured.

When is adjustment of the clutch drive mechanism necessary?
Despite the presence of innovative ideas in the field of transmission control, Togliatti automakers still recommend checking the condition of the ratchet mechanism at every maintenance. In addition, it would be a good idea to pay attention to the signs that indicate problems with the clutch control system:
- Loss of traction due to unreliable connection between the flywheel and the disk.
- “Sagging” of the clutch pedal.
- Difficulty changing gears.
- Extraneous sounds when using the clutch pedal.
The symptoms are generally identical to those when the drive needs to be adjusted on a VAZ 2110, i.e. their identification should not cause any problems. It should not be forgotten that the automatic tensioner has its own compensation limits. The working stroke of 27 mm is the same stroke of the compensator.
In other words, during the operation of the disk, the fork moves precisely by this length. Therefore, the problem of how to adjust the clutch on a Priora car can practically be solved in an elementary way. Even if you want to, you won’t be able to overload the release bearing.
How to check the clutch drive parameters of a VAZ 2170?
A few simple steps will help you make sure that the drive needs to be configured:
- Open the engine compartment hood.
- Disconnect the MAF sensor and remove the air filter.
- Just below the battery, find a cable with a plastic clip.
- Pull the mechanism clamp forward in the direction of travel.
- Holding the tip in an extended position, measure the distance L (in the photo), the norm corresponds to 27 mm.
What are the main faults in the Priora clutch cable?
When the clutch cable on a Lada Priora is already in a state close to failure, or even possibly has failed, the driver will immediately feel it. When an attempt is made to engage the clutch in order to shift or engage a gear. Main types of breakdowns:
- The drive fastener to the pedal or probably the fork is broken. Always at such a moment the pedal will fall to the floor.
- The cable is disheveled. In this case, it is almost impossible to press the clutch pedal.
- The cable has broken. In this case, the pedal also falls freely.
All this indicates that it is time to conduct a thorough check of the drive on the Lada Priora. Each of the above malfunctions indicates that the clutch cable needs to be replaced and everything can be done even with your own hands. There is no point in replacing individual parts.
If you need to service your all-wheel drive, then you need to contact specialists and they will carry out preventive work for you; a car with all-wheel drive requires constant monitoring of the units.
Priora clutch adjustment: detailed description of settings
Carrying out such an operation as adjusting the clutch on a Priora is of interest to many novice motorists. The fact is that this technical problem occurs quite often when operating a car. Clicking noises may be heard while driving. The cause of the sounds is a malfunction of the clutch drive. It is not difficult to get rid of this problem with your own hands.
Removing clutch pedal clicks
How to adjust the clutch? If the clicking becomes constant, then you can get rid of this problem in a simple way, showing a little ingenuity, and you need to use an ordinary ruler. As a rule, clicking sounds come from the clutch control unit. You need to do the following: open the hood of the car and inspect the area to the left of the battery. This is where the clutch cable goes into the fork. To inspect it you will need to pull it out of the plug.
Using a ruler, measure the distance from the base of the cable to the adjusting screw. The distance must be exactly 27 mm. The main factor in adjusting the Priora clutch is accuracy. It should be noted that this indicator should in no way increase or, conversely, decrease with a deviation of even one millimeter.
Otherwise, the pedal will continue its annoying clicking. Now you need to put the cable back. After adjusting the distance, you need to depress the clutch pedal several times. Having eliminated this problem, the softer operation of the clutch release pedal will immediately become noticeable, compared to how it worked before the adjustment.
Causes of breakdowns and solutions to problems
Domestic automakers are not particularly reliable and durable in their parts and assemblies. It is not surprising that many car components quickly fail and are no longer suitable for further use. All this causes many car owners to have characteristic problems in the operation of the clutch mechanism on their car. However, you should not blame only car manufacturers for all the problems that arise, since many malfunctions are the result of careless operation of the car by the car owner himself.
| Cause | Solution |
| Insufficient pedal travel causes the clutch itself to “drive” | To eliminate this defect, it is necessary to regulate the mechanism drive itself. Car service station professionals can help solve this problem. |
| Clutch pedal sticking | This problem usually occurs when parts of the drive mechanism are damaged. This can be resolved by replacing the damaged part. |
The cable should be adjusted as often as possible. The fact is that such preventive work helps to avoid a number of problems and, accordingly, allows you to save a considerable share of the financial resources of car owners. Normal operation of the clutch mechanism is the key to safe operation of the vehicle.
Replacing the clutch cable and clutch sensor
Carrying out such a technical operation as replacing the clutch cable on a Priora must be performed in the following cases:
- breakage of a spare part;
- tight action in the shell.
To replace the clutch cable on a Priora, you need a certain set of screwdrivers and wrenches. The first part that needs to be removed is the air intake filter located in the engine. In this case, the clutch cable must be pulled forward and then removed from the cell of the lever system.
This is done using a key number 17, making a certain number of turns of the nut, which secures the tip of the part in question directly to the bracket itself. To perform this operation, you must secure it firmly with a hexagon. The tip is removed directly from the bracket itself. This element is located in the interior of the Lada Priora. This nut securely fixes the bracket and is turned using a number 8 wrench.
Clutch: 1 – cable tip guide; 2 – clutch release fork lever; 3 – clutch casing; 4 – bolt securing the clutch to the flywheel; 5 – pressure disk; 6 – flywheel; 7 – driven disk; 8 – gearbox input shaft; 9 – front cover of the clutch housing; 10 – clutch housing; 11 – pressure spring; 12 – clutch release bearing
Considering that replacing the cable itself on the Lada Priora is carried out in a hard-to-reach place, to make the work easier, it is recommended to apply a little effort, and you will need to push the pedal itself. Using such a simple tool as a screwdriver, you need to pry off the back side of the pedal. After this, the part is dismantled.
The next step is to pull the cable out of the hole in the sealing cover. Immediately after dismantling, you need to unscrew and remove the so-called leash from the tip. If the clutch sensor of the vehicle in question has lost its performance, it is replaced with a new unit.
As for the installation of the clutch cable itself, this action must be carried out after diagnosing the condition of the plastic bushing. If this part has exhausted its service life, it is replaced with a new one. It is recommended to treat the pin, like the bushing, with a special lubricant.
Installation of the clutch cable part on a Priora car is carried out in a hole located in the shield and passing from the passenger compartment to the engine compartment. First, the cover for the seal is installed, then the mechanism body itself is installed on the cable pin. After fixing it, it is necessary to secure the cable sheath.
The tip of the wiring is rotated in a certain way, so that its end is at the level of the leash, the latter must be installed in its place. The next step is to regulate the clutch drive itself on the Priora. This operation helps to pull the cable forward by its tip until it stops completely. In this arrangement, it is possible to measure the distance from the lever itself to the end. This distance should be 27 mm.
The required dimensions can be achieved by rotating the wire. Its adjustment allows you to remove the load by pressing tightly against the lever, and at the same time, the gaps are removed. After this, you need to press the clutch pedal three times. This action allows the automatic distance control mechanism to begin to operate. You also need to take into account that the full pedal travel should not exceed 146 mm.
It is best to carry out diagnostics in a timely manner to avoid side effects with the further development of more global breakdowns. Such necessary actions as diagnosing the operation of the car’s clutch allow the owner to save a considerable amount of money and make his car safer.

Changing the clutch cable on a Priora
As we said, replacing the clutch cable in your LADA Priora is possible with your own hands, the most important thing is to know how to change it correctly. Read more about this.
To replace you will need the following tools:
- The keys are ordinary 8“/17“.
- Pliers/screwdriver/pry bar.
The replacement begins with dismantling the old drive, and you need to start from the interior of the LADA Priora. You will have to do everything with an assistant. Algorithm of actions:
- Slowly release the clutch fork. In this case, an assistant removes the cable fastening bracket from the pedal.
- Unscrew the fastening of the casing near the pedal. Use key 8 for this.
- Let's move on to the engine compartment, and using a screwdriver you should carefully pull out the seal there and pull the cable out there.
- We disconnect the negative terminal of the battery, since the work will be carried out next to the starter drive.
- Remove the air filter. Access to the cable fastening is now open.
- Using a 17 key, we easily release the shell latch. Thus, the core will be weakened and the tip in the fork at the point where the clutch is engaged can be freely removed.
- Remove the casing from the groove. This is all that is required for the drive to become free.
- Let's go to the salon. Let's start installing the new device. At this stage, the assistant must pull the cable from the engine compartment into the passenger compartment. Before starting installation, lubricate all open areas of fastening the tips and the core itself.
- We place it properly in the cabin, secure the tip mechanism, of course, to the pedal.
- Attach the casing.
- We press out the fork and attach the clamp directly to the fork.
- We put it in the place where the casing is supposed to be fastened, directly on the gearbox. Using a 17 key, we adjust the tension of the device in question.
- We fix the seal that was previously removed from there in a special hole in the passenger compartment.
- We put a device such as a car air filter in its rightful place.
Features of the Lada Priora clutch
Any motorist interested in how to adjust the clutch on a Priora should know about the presence of the drive cable auto-adjustment function. That is, VAZ designers took care of the owner and saved him from the need to constantly adjust the clutch drive mechanism during operation. The same ratchet-type system is installed on Kalina, but both there and on Priora it is impossible to do without periodic adjustments. This factor has been proven by practice and forum discussion pages.
How does an automatic cable tensioner work?
In the release drive on the VAZ 2170, there are no gaps as a concept, hence the name - backlash-free clutch. The ratchet mechanism serves to compensate for the working length of the cable as the driven disk linings wear out. To understand the process, it is important to accept the following data:
- During operation, the driven disk wears out and its linings become thinner - as a result, the release bearing and basket springs shift towards the gearbox.
- Accordingly, the fork at the place where the cable is attached moves towards the radiator.
- The spring located on the bushing of the adjusting mechanism is compressed at this time and tightens the clamps of the cable tip.
- As a result, the tip is pulled out of the driver, due to which the wear of the disc linings is compensated.
It wouldn't hurt to know
What do most owners of new Lada Priora do? Naturally, they treat the body with Movil or something similar against corrosion; they don’t have any more problems at the initial level. However, there were complaints about squeaking when pressing the clutch pedal; sometimes it was present when the engine was warm, sometimes only when it was cold - the essence is that there is a problem.
Of course, everyone immediately starts reading the “primer book” on how to correctly adjust the clutch on their Priora, which sometimes helps, but the fact of the matter is that sometimes. After this, owners can try several more methods, after which the squeak may disappear:
- Replace the drive cable, some drivers praise the “tenth”.
- Check the presence of a spring in the automatic tension mechanism; sometimes the effect can be achieved after replacing the standard part with a spring with greater elasticity.
- A certain percentage of car enthusiasts get rid of the crackling noise by lubricating the fork and the plastic cable nut.
- Lubricate the installation site of the plastic bushing on the pedal bracket with lithol.
- Remove the boot from the fork lever and lubricate the gearbox input shaft with graphite grease from a can.
It is worth considering another effective method, shown in the video, which is used by experienced car enthusiasts. Its essence is as follows:
- Disconnect the mass air flow sensor and remove the air filter.
- Remove the clutch release rod plug.
- Release the cable from the clutch fork.
- Pour 30-40 ml of gear oil from a syringe.
- Move the fork back and forth 10-15 times.
- Reinstall the cable, plugs and filter.
Using the example of the second part of the article, it becomes clear that adjusting the clutch drive does not always bring the desired effect in the fight for acoustic comfort. Although, from a technical point of view, the procedure is necessary, since it ensures productive operation of the car.

The clutch does not disengage completely (drives): the main reasons
| Replace the driven disk | |
| Wear of the diaphragm spring blades at the point of contact with the release bearing | Replace drive disc assembly |
| Jamming of the driven disk hub on the splines of the input shaft of the gearbox | Inspect the splines; if the hub is significantly damaged, replace the driven disk. Before assembly, apply CV joint-4 lubricant to the gearbox shaft splines. |
| The driven disk is “stuck” to the flywheel or drive disk (after a long stay) | Place wheel chocks, engage first gear and parking brake. Press the brake and clutch pedals simultaneously and turn the engine crankshaft using the starter. |
| Incorrect clutch drive adjustment (full pedal travel is too small) | Adjust the drive |
| Loosening of rivets or breakage of friction linings, warping of the driven disk (axial runout in the area of the linings is more than 0.5 mm) | Replace the driven disk |
| Severe and uneven wear, scoring on the working surfaces of the flywheel or pressure plate | Replace flywheel. If the pressure plate surface is damaged, replace the clutch cover |
| Distortion or warping of the pressure plate | Replace clutch cover |
| Jamming of the driven disk hub on the splines of the input shaft of the gearbox | Clean the splines from dirt, remove minor damage with a file. If the splines are significantly worn or damaged, replace the transmission disc and/or input shaft <STO> |
| Loosening of the rivets of the spring plates of the clutch housing, breakage of the plates | Replace clutch cover |
| Clutch release bearing jammed | Replace bearing |
Clutch leads
The term clutch “floats” means that the clutch does not disengage completely when the clutch pedal is depressed. When the clutch pedal is released, it is constantly on. After pressing the pedal, the force is transmitted through the cable and fork to the release bearing, which presses on the petals of the “basket” pressure spring. The spring acts on the drive disk, which stops pressing the driven disk against the working surface of the flywheel. The transmission of torque from the engine to the gearbox is interrupted. You can change gears.
If for some reason the driven disk is not sufficiently moved away from the flywheel, shifting forward gears will be difficult, and the rear gear may engage with a crunch and crackle.
Reasons that the clutch is leading
Clutch drive not adjusted
Full pedal travel is insufficient. The clutch pedal is located below the brake pedal.
adjusting the clutch drive by rotating the adjusting nut
Drive cable jamming in sheath
Over time, the drive cable may wear out, the wires in it become frayed, which makes it very difficult to move in the sheath. As a result, when you press the pedal, the clutch does not disengage completely (drives).
The driven disk is faulty
The driven clutch disc may be warped (its end runout is more than 0.5 mm). The driven disc hub may bind to the input shaft splines if they are heavily dirty or worn. In any case, the driven disk will not move away from the flywheel to the required clearance.
The flywheel or pressure (drive) disk of the basket is faulty
Severe scuffing on the flywheel or drive plate working surfaces may prevent the driven disc from rotating freely.
The clutch pressure damper spring is faulty
Severe wear of the ends of the spring petals at the point of contact with the release bearing.
Notes and additions
— In some cases, difficult gear shifting can be caused by reasons not related to the clutch. For example, breakage, deformation, incorrect adjustment of drive elements of the gear shift mechanism.
