Popular domestic model

Lada Kalina is very popular with Russian motorists, but most of its owners note that the model has a number of significant drawbacks. In particular, complaints are caused by the appearance, comfort and technical equipment of the car.

A lot of claims are made regarding how the Lada Kalina clutch works.. Although reading the instructions for this vehicle, it is difficult to believe that any malfunctions may occur during clutch operation.

Clutch device

The clutch of this model from AvtoVAZ is single-disk and belongs to the dry subtype. It is equipped with a pressure spring located in the center. The pedal is connected to the clutch disc using a special cable, the length of which is regulated by a ratchet mechanism. This can be seen if you watch a video demonstrating the design of Kalina.

Overlays of a dependent disk in the course of use are erased and become thinner. The fault is eliminated by a ratchet mechanism that compensates for wear by tightening the cable. The tension causes the release fork to rotate and compresses the spring, which is located in the sleeve of the regulating mechanism. The spring, in turn, compresses the latches placed on the toothed tip of the cable. As a result of all these manipulations, the tip is released and the cable is pulled.

The ratchet mechanism eliminates the need for car owners to spend time and effort on adjustment. But this is only in the theory developed by Kalina's designers. In reality, when operating the machine, you need to know how to adjust the clutch yourself.

When Adjustment Is Needed

Clutch setting

Clutch adjustment is only carried out with the engine off. It is necessary when deviating from the following values:

the full pedal travel does not exceed 146 mm;
movement of the cable leash relative to the release fork lever - within 270 mm;
the runout of the overlays of the dependent disk does not exceed 0.5 mm;
the distance between the pads and the rivets that hold them is 0.2 mm or less.

There are several ways to check if a car needs clutch adjustment.

You should press the pedal several times in a row and listen for extraneous noises. If the clutch pedal sticks or creaks, it is advisable to make an adjustment. In some cases, car owners cannot visually assess whether the pedal returns freely to its place. In such situations, it is recommended to do the following:
- hold the clutch by hand until it stops;
- stop the force, but leave your hand on the pedal in order to feel if there is a move.
If the clutch pedal sticks and clicks or it returns to its original position with characteristic twitches, you need to adjust the clutch.
It is necessary to measure the distance from the floor to the outer part of the pedal using a ruler or caliper. Then you should press the pedal so that it rests on the floor. After that, you need to release the pedal and re-take measurements. If the distance exceeds 146 mm, be sure to adjust the clutch.

Like all "basins", Kalina is not at all flawless. For more than a decade of history, the model has been refined more than once, but it has not been possible to get rid of some problems. It is recognized among the Kalinovods that the torque transmission mechanism, due to its design features, is the weak link of the car. Despite all the upgrades in this area, motorists have to periodically adjust the clutch.

Features of the clutch VAZ 2112

The machine is equipped with a dry type single plate friction clutch with a central pressure spring. Any motorist, before adjusting the clutch on Kalina, must take into account that the control pedal is connected to the disc by means of a cable with a special ratchet mechanism.

How does the automatic cable tightening work?

As a result of intensive use, the friction linings of the disc gradually wear out. The ratchet mechanism built into the drive design allows for some period of time to compensate for wear - it pulls the cable a little. During operation of the device, the fork rotates and the sleeve spring is gradually compressed. As a result, the clamps of the cable tip are compressed, after which the latter is released and pulls the cable.

The purpose of this design is to facilitate the maintenance process. According to the plans of the VAZ engineers, the mechanism should relieve the owner of the need to make adjustments on their own. But this is all only in theory, but in practice it turns out that one cannot do without adjusting the clutch.

Before adjusting the clutch on Kalina's car, you need to determine the moment when the cable auto-lock is no longer functioning. This is not difficult, especially since the machine itself signals problems:

Loss of thrust, friction clutch does not provide a reliable connection between the flywheel and the disk. The consequence of such a defect will be the loss of a significant part of the torque force.
The clutch control pedal does not return to its original position, which, in fact, is a consequence of the first paragraph.
Poor clutch disengagement - the pedal is not pressed all the way, which makes it difficult to shift gears.

The symptoms, however, are similar to those when clutch adjustment is needed on the VAZ 2107, so experienced motorists can skip this block and proceed directly to the test.

How to check the clutch?

To make sure that the mechanism needs to be adjusted, a number of elementary checks should be performed:

Press the pedal several times and release - any extraneous sounds are unacceptable. For better control, you can press it with your hand, so the pedal travel is more fully felt.
Check the pedal for jamming, if it returns with noticeable twitches, then you can’t do without adjustment.

Check the full travel of the pedal with a ruler or tape measure. Press and release the pedal several times, then measure the distance of its outer edge to the floor, if it is more than 146 mm, then the mechanism needs to be adjusted.
Control the movement of the cable leader relative to the clutch release fork, the maximum distance between these elements is 27 mm.
When the beating of the lining of the driven disk is more than 0.5 mm, adjustment is also required.

When performing checks, it is important that the car engine is turned off.

Without noise and dust: how to properly adjust the clutch on the Kalina station wagon on your own?

It is necessary to start work not earlier than the engine has completely cooled down. The setup procedure is simple and does not require a visit to a car service, because you can do everything yourself. The step-by-step scheme of work is as follows:

Before adjusting the clutch drive on Kalina, you should open the hood of the engine compartment and dismantle the air filter.
Visually assess the condition of the cable casing and replace it if damaged.
Pull the tip towards you so that the cable takes full tension. After that, check the distance between the fork and the leash with a caliper.
If the measurements showed more than 27 mm, then the distance is corrected by rotating the leash along the thread of the tip.
Press and release the clutch pedal several times, repeat the measurements.
If necessary, repeat the adjustment until the required standards are obtained.

The technology for setting up the clutch on Kalina is not as complicated as installing the VAZ 2110 clutch, therefore it is quite feasible in garage conditions without the involvement of specialists. And this fact pleases domestic motorists, because the clutch plays an important role in driving.

We adjust the clutch on the Lada Kalina step by step

One of the disadvantages of Lada Kalina is clutch problems. To avoid visiting a car service and save time and money, you can diagnose a malfunction and adjust the clutch on Lada Kalina with your own hands in the garage. The article describes step by step how to adjust the clutch, as well as a video that demonstrates the entire procedure.

Lada Kalina is equipped with a "dry" clutch with one disc and a central pressure spring. The disc is connected to the clutch pedal (PS) with a cable. The interaction is carried out with the help of a cable, which is a weak point in the knot. Adjustment is carried out using a ratchet mechanism, which is a rod with a thread and a control nut.

Clutch diagram for Lada Kalina

Over time, the pads wear out, on the disk, they become thinner. In many ways, wear depends on the driving style of the driver. Whoever likes to tear from place, the knot will not last long and will need to be repaired. With the help of a ratchet mechanism, the insufficient thickness of the lining is eliminated by pulling the cable. This happens by turning the release fork, it causes the spring located in the sleeve to compress. The spring acts on the latch of the tip, releases it and, thus, the cable is stretched.

Correct cable length adjustment

Thanks to the ratchet mechanism, the cable length is automatically adjusted. But, despite this, sometimes you have to manually adjust.

There are clear signs by which you can diagnose whether the clutch assembly needs to be adjusted, namely:

problems when shifting gears;
extraneous sounds when squeezing the PS: creaking, friction, clicks;
the clutch does not turn off / turn on completely;
poor traction;
jamming during the movement of PS.

In the video of Sergey Tsapyuk, the reason for the tight pedal release and the way to fix the problem are analyzed.

With the help of simple actions, you can identify other signs indicating that you need to adjust the clutch on the Lada Kalina:

If the symptoms listed above are found, then it is necessary to either adjust the clutch or replace it.

Required Tools

To carry out the procedure, you will need a minimum of tools:

key set;
crosshead screwdriver;
ruler;
calipers.

Stages

On the video you can clearly see the adjustment process, the step-by-step adjustment steps are described below:

Ideally, the PS should be at the same level as the brake pedal or slightly higher.

During adjustment, attention should be paid to the protective cover. If it has any damage, cracks, it must be replaced to avoid repair work in the near future.

How to manually adjust the clutch on Kalina

During the operation of the car, the driver is faced with a number of problems that indicate that clutch adjustment on Kalina is necessary. Due to the peculiarities of the mechanism installed on these VAZs, even if the lining of the driven disk is worn, the clutch release cable automatically lengthens. This allows the motorist to correct the pedal travel only occasionally, in the event of a malfunction. But even in these cases, it is possible to do it on your own, without resorting to the services of a car service.

The device and operation of the Kalina clutch

The unit belongs to the dry type mechanisms, single-disk, with a central pressure spring. Switching off when pressing the pedal is carried out by a cable equipped with a ratchet. This part allows the cable to automatically change length depending on the wear of the disc linings and ensures a constant backlash-free fit of the clutch with the release bearing to the basket.

The pressure plate, together with a diaphragm-type spring, is enclosed in a casing. All together and it is customary to call the clutch basket. Between this mechanism and the flywheel is a driven disk. Its hub is connected to the gearbox input shaft.

When exposed to the pedal, the cable is pulled, turning the fork. Its lower sleeve is pressed into the clutch housing, the upper one is removable. The force when turning the fork through the clutch and the clutch release bearing is transmitted to the pressure spring and the pressure plate, turning off the mechanism.

When the pedal is released, the clutch must fully transfer the engine torque to the transmission. Pressing the pedal normally completely disconnects it from the engine. Signs of the need to adjust the clutch on Kalina can be considered:

exceeding the full travel of the pedal (normally - 146 mm from the position in the lowered state to the stop on the floor) - adjustment of the clutch cable is necessary;
when the pedal is pressed, the gear is switched on with a rattle or crackle - the clutch does not turn off completely;
when starting the engine, a howl is heard in the crankcase - wear of the release bearing;
jerks at the beginning of the movement indicate insufficient smoothness of the clutch engagement;
when driving in 3-4 gears, when you press the gas, the engine speed quickly increases, and the acceleration slows down - slipping of the discs, possibly due to wear of the pads or insufficient length of the cable.

As a rule, it is necessary to correct the operation of the clutch after its repair in order to bring the automatic adjustment mechanism into working condition.

This operation may also be required if Kalina has not been used for a long time or worked in the winter.

In such cases, the wear compensator may lose some of its functions and cannot cope with the adjustment of the length of the cable.

Correction of the mechanism

If various extraneous sounds appear during the clutch disengagement during the operation of the car, you need to check the gap on the drive fork and, if necessary, correct it. The clutch cable is adjusted in the following order:

Remove the air filter and pull the cable at the end to the maximum length.
Use a caliper to measure the distance between the tip and the fork. Normally, this distance should not deviate from the value of 2.7 mm.
If discrepancies are found, turn the driver on the thread until the desired value is established. Release the tip of the cable: in doing so, it should be firmly pressed against the fork.
Press the clutch pedal 3-4 times to activate the automatic cable length correction, measure again.

When re-measuring, a deviation from the value of 2.7 mm may again be detected. In this case, you need to repeat the described steps to adjust the length of the cable.

The clutch on Kalina can make squeaks and noises even after adjustment. They can be caused by the tip leash rubbing against the fork. The noise in this case comes from the engine side and is eliminated by applying lubricant to the contact point of the cable end nut and fork. Other possible causes - pedal creaking, cable grinding when rubbing against the casing - are eliminated by applying lubricant. In some cases, the clutch pedal sensor may be the source of the noise.

On a Lada Kalina car, the clutch is turned off, turned on with a metal cable. If it breaks, the cable must be replaced. This article provides information on replacing and adjusting the clutch cable.

Tools needed to replace and adjust the clutch cable: 8 mm wrench, ruler, screwdriver

Operations to replace the clutch cable on a Lada Kalina car

1. From the passenger compartment under the instrument panel (for clarity, work is shown with the panel removed) unscrew the nut securing the cable sheath stop to the pedal bracket and remove the stop from the stud.

2. Using a screwdriver, remove the locking bracket and the housing of the clutch wear compensation mechanism from the clutch pedal rod.

3. In the engine compartment, pull out the clutch cable sheath seal from the hole in the partition located between the passenger compartment and the engine compartment.
4. While pulling the cable forward in the direction of vehicle travel, pull the cable out of the recess on the clutch release fork.

5. Unscrew the leash from the cable tip, remove the cable sheath guide bushing from the hole on the gearbox bracket and remove the cable from the vehicle by pulling it out of the hole in the bulkhead.

6. Installing a new clutch cable, start by passing the cable through the hole in the bulkhead, fasten it to the clutch pedal shaft, and also fasten the wear compensation housing.
7. Attach the cable sheath stopper to the pedal bracket stud.
8. Install the cable sheath seal in the baffle opening.
9. Pass the cable through the bracket hole on the gearbox and install the cable sheath guide bushing into the hole.
10. Screw the leash onto the lower tip of the cable, ensuring that the tip protrudes 0-1 mm relative to the end of the leash.

Clutch cable adjustment operations Lada Kalina

1. Set the clutch cable to its original position, to do this, overcoming the force of the mechanism spring, move the lower tip of the cable forward as far as it will go, that is, in the direction of the vehicle. Hold the tip in the extended position, measure the size (see size L in the photo) between the fork and the leash, it should be equal to 27 mm. If the size does not correspond to the proper value, then adjust it by rotating the leash in the desired direction.

2. Insert the tip of the cable into the groove of the clutch release fork and release. Under the action of the spring, the tip leash should be installed on the fork without a gap.
3. Press the clutch pedal several times until it stops and again measure the previously controlled distance (see photo size L). If necessary, repeat the adjustment until you reach the desired value of 27 mm.

Additional information about the clutch cable compensating mechanism

The compensation mechanism on the clutch cable Lada Kalina is designed to ensure that the clutch cable is always taut. A slight deviation of 1-2 mm is either "selected" by the compensating mechanism or added to the length.

Undoubtedly, Lada Kalina is a fairly popular car among domestic motorists. Moreover, the fact that it has a fairly large number of flaws and shortcomings does not at all affect the high popularity of this particular model from the fret family. Clutch on viburnum has always been problematic. If you look at the clutch design itself, it's hard to believe that the fret has problems there and quite frequent clutch adjustment on viburnum is required.

Clutch design on Lada Kalina

The Lada Kalina car is equipped with a dry clutch type, which has a single disc and a central pressure spring. The design of the fret has a ratchet mechanism for adjusting the length of the cable. The process of work is accompanied by constant erasure of the friction linings of the disc, and the cable changes its tension from this, and here the ratchet mechanism comes into play, which compensates for this wear. The working process of the ratchet mechanism is as follows:

From the tension of the cable, the release fork rotates, thereby forcing the spring to compress;
The compression of the spring causes compression of the clamps, which are located on the toothed tip of the cable;
The tip is released and the cable is tensioned.

Naturally, this is a theory that was used in the design of the viburnum fret. The reality is somewhat different from the theory, viburnum clutch simply forces its owners to sometimes roll up their sleeves and adjust it. Do not be afraid to do it yourself, because this is a fairly simple procedure, because the viburnum clutch itself is so simple in design that even replacing the assembly is not a particularly difficult job.

Signs You Need to Adjust Your Clutch Cable

It is necessary to adjust the clutch cable after the appearance of such signs:

Extraneous sounds when disengaging the clutch;
Problems when shifting gears;
Bad traction;
Incomplete clutch disengagement.

You can check the clutch by performing a few simple steps: with the engine off, you need to squeeze the clutch pedal several times, while you should listen carefully to see if there are any extraneous noises in the process of pressing.

If during this procedure you hear noises or feel increased play or pedal sticking, then most likely it is worth adjusting the cable, but first pay attention to its appearance, if the cable itself is rusted or has tears in the attachment points, then you may need to his replacement.

However, not all motorists can freely determine backlash and jamming “by eye”. In such cases, it is best to press not with your foot, but with your hand, because it is a more sensitive human organ.

There is a more effective way to check the adhesion of viburnum. It consists in measuring the pedal travel, for this you need:

Measure the distance with a ruler from the floor to the pedal itself;
Squeeze the clutch pedal "to the floor" and again measure the distance;
Perform the procedure several times for the most accurate result.

And now we compare the obtained value with the regulated one, which is 146 mm. If you matter more, then adjustment is simply inevitable.

How to adjust clutch cable

So, the fact that it is necessary to adjust the clutch on the viburnum is already clear, it is only unclear how to do it. There is nothing complicated and it is not necessary to resort to the services of car services, because you can do it yourself. Consider the whole procedure in stages for a better understanding of the process:

Open the hood and remove the air filter;
Visually evaluate the cable and, if it is in poor condition, then it is replaced with a new one;
Using a caliper, measure the distance between the leash and the fork arm;
If the value obtained is higher than 27 mm, then it is necessary to correct it by rotating the leash along the thread of the tip;
Press and release the pedal several times and repeat the procedure;
It is necessary to repeat until the results are aligned with the regulated value.

You can see that the procedure is quite simple and it will not be difficult to perform it yourself. But still, if you still failed to adjust the cable, then contact a car service, because a breakdown directly in the node itself is not ruled out, which means that it is necessary to replace any element or the entire node as a whole. And although the fret is easy to repair, complex work is best done by trained specialists.

The car is equipped with a single-disk dry-type clutch with a central pressure spring. The clutch release drive is cable-operated, backlash-free, with a mechanism for automatic adjustment of the cable length.

The clutch consists of a basket (pressure plate assembly) and a driven plate. The basket is a steel casing in which the pressure spring and the pressure plate are installed. The pressure plate is fixed in the casing on three pairs of elastic plates. From the side of the casing, the disk is pressed by a pressure spring of the diaphragm type. The clutch basket is attached with six bolts to the flywheel and is covered with an aluminum crankcase. A driven disk is installed between the pressure plate and the flywheel.

Friction linings are riveted to two sides of the driven disk. To dampen torsional vibrations at the moment the clutch is engaged, a damper with six coil springs is integrated into the driven disk. The hub of the driven disk enters splined engagement with the input shaft of the gearbox.

The clutch pedal is suspended on the axle and is attached to the body through the bracket. The upper part of the clutch pedal is made as a two-arm lever. At the end of the lever there is a pin to which the clutch release cable is connected. The connection is made through a special ratchet mechanism that regulates the length of the cable (see below). Therefore, during the operation of the car, it is not necessary to regularly check and adjust the travel of the clutch pedal. This mechanism also ensures that there is no play in the clutch release actuator.

Clutch release cable: 1 - spring fixing bracket; 2 - automatic cable length adjustment mechanism; 3 - tpoca shell bracket; 4 - rubber cover; 5 - cable sheath; 6 - corrugated cover of the lower end of the cable; 7 - threaded (lower) cable end

The cable is laid in a metal sheath with a polyethylene coating. The upper end of the shell has a bracket that is attached to the pedal assembly. The vertical surface of the bracket also serves as a travel limiter for the clutch pedal. A rubber plate is installed on it. The lower end of the cable sheath is fixed in a bracket mounted on the gearbox housing. The lower end of the rope is closed with a rubber corrugated cover. The cable is connected to the clutch release fork lever through a plastic leash screwed onto the threaded end of the cable.

The clutch release fork rotates in two bushings. The upper sleeve is plastic, removable, and the lower one is bronze, pressed into the clutch housing. When the fork is turned, the force is transmitted to the pressure spring petals through an angular contact ball bearing (release bearing). The bearing is put on the clutch release clutch, through which it contacts the clutch release fork. The constant engagement of the fork and the clutch is provided by a U-shaped spring. Due to the lack of play in the clutch release drive, the clutch is constantly pressed against the pressure spring petals, while the release bearing is continuously working. The bearing is lubricated for its entire service life. The clutch release clutch moves along the guide sleeve, put on the input shaft of the gearbox and attached to the clutch housing with three bolts.

During operation, the lining of the driven disk wears out. To compensate for this wear, an automatic cable length adjustment mechanism is built into the clutch release actuator. As the pads wear, the clutch release fork lever, turning, pulls the cable. In this case, the spring is compressed, located in the bushing of the adjustment mechanism and pressing the clamps of the toothed tip of the cable. The retainers release the tip, as a result of which it is freely pulled out of the cable leader, compensating for wear on the disc linings. When you press the clutch pedal, the upper leash moves up. At the same time, the clamps compress the toothed tip of the cable, preventing it from moving out of the body of the adjustment mechanism.

Cable length adjustment mechanism:

1 - sleeve; 2 - leash; 3 - notched (upper) tip tpoca; 4 - clamps of a tip of a cable; 5 bracket (with clutch pedal limiter)

Note. On the cars of the first releases, a spring was installed inside the leash.
