All motorists who have cars with a manual transmission know the role of the clutch. And they also know what happens to a car when the clutch loses. In this case, to correct the situation, you will need to visit a service station and replace the clutch there. This work usually takes 1–2 hours. Although this method of repair is considered fast, it is expensive. To save money, you can try to do this work yourself in the garage.
What is clutch?
This is the unit through which torque from the engine is transmitted to the gearbox.
When the clutch does not work at the proper level, it will not only make it difficult to engage a particular gear, but will also negatively affect the operation of the engine and gearbox itself.
Clutch Niva Chevrolet VALEO.
On the Niva Chevrolet the clutch drive is hydraulic . And it also has automatic compensation for lining wear. The clutch drive is also of great importance, since it is with its help that the driver can control the clutch.

When does it make sense to renovate?
The manufacturer did not provide for the possibility of repairing parts. In addition, clutch spare parts are not very expensive. Therefore, if a malfunction is detected, it is necessary to replace the worn part with a new one.
Sachs clutch
The Sachs clutch is produced by the German concern ZF. Sachs is famous for its wide network of concerns located in 39 countries. The Sachs clutch kit has the following advantages:
- The kit does not require maintenance.
- There are no asbestos linings.
- Copes well with increased loads.
- The clutch kit from Sachs for the Chevrolet Niva has gained enormous popularity in the CIS countries.
But it is worth highlighting one drawback that is a hindrance for budget car enthusiasts - the high cost of the product. The manufacturer also claims that the Sachs clutch kit has a service life of 100,000 km. But is it really so - you, dear Shnivovody, check. The kit costs approximately 5,500 rubles, but you still need to look for it.
Clutch malfunctions on Niva Chevrolet
To accurately determine a clutch malfunction, it will not be enough to quickly list such points, since it is a fairly large unit. Therefore , only the main malfunctions that occur with the clutch will be given below .
- The clutch does not fully engage (slips) . Here the reason may be severe wear of the linings. You'll have to change the disk.
The clutch may slip due to wear or oiling of the friction linings of the driven disc.
You can determine the malfunction of certain clutch elements by the characteristic sound when the gear is engaged.
Replacing the clutch yourself
When the cause of the malfunction is identified, it will be necessary to carry out repairs and take measures to eliminate the breakdown .
If you do such work yourself, then this is a long process that will take a lot of time. And also all activities should be carried out according to the instructions.
Sequencing:
- Prepare a set of keys and a mandrel for centering the driven disk.
Mandrel for centering the driven disk.
We remove the gearbox.
We mark the relative positions of the disc casing and the flywheel.
We unscrew the six bolts securing the pressure plate to the flywheel.
Let's remove the pressure and driven discs and do a visual inspection.
We check the reliability of the damper springs.
We evaluate the condition of the pressure plate diaphragm spring.
When all these indicators are missing, then the disk can be left old , changing only the release disk. Assembly is carried out in reverse order.

This malfunction also occurs if the rivets on the friction linings are too loose. Replacing the release bearing of a Niva Chevrolet A sign of the need to replace the clutch release bearing of a Chevy Niva is increased noise when the clutch pedal is pressed. Release lever on Niva Chevrolet:
Let's look at its structure and repair. At this stage, the process of replacing the main clutch parts is complete. At this time, the torque on the gearbox shaft disappears and the transition to the next gear can be made.
It happens that, on the contrary, it does not turn off completely, it starts to drive, this can be for the following reasons: The driven disk has warping or beating, this malfunction can be solved by repair, unless of course it has minor damage. But as a rule, if this malfunction occurs, it can be solved only by completely replacing the disk.
The rivets on the fixed pads have become loose. The driven disk set will need to be replaced. There is air in the system itself. This can be solved by pumping the system. Warping and distortion of the disk. You can solve it by replacing this part. A malfunction may occur when some parts and components need to be replaced.
This is determined by the following signs: And put everything back together in reverse order. In some cases, when the clutch does not disengage completely due to leaks, other work must be carried out.
An assistant may also be required to complete them. Together you need to replace the clutch slave cylinder.
First, loosen the hose tip on the cylinder. Then the bolts of the mounting bracket to the crankcase are unscrewed. After this, you can remove the pusher from the fork along with the protective cap.
The clutch cylinder is completely disconnected from the hose. All that remains is to install the new part and bleed the hydraulic drive. Replacing related parts Sometimes it is necessary to replace the hose that is included with the mechanism. To do this, use a key to hold the fitting. In the meantime, the pipeline is disconnected.
The fitting mounting bracket is also dismantled.
Next, you need to drain the fluid from the drive. The hose tip is then disconnected from the working cylinder. After installing a new one, the hydraulic drive should be bled. Sometimes it is necessary to replace the tank if deposits have formed on it. To do this, remove the plug. Unscrew the fasteners and dismantle it.
Removing the Niva Chevrolet gearbox and replacing the clutch
Then you should visually check the walls. If there are no deposits, then after thorough washing it can be used further. The driver may hear a loud noise when pressing the pedal. This is a signal that the release bearing is faulty. Then disconnect the bearing from the clutch fork and remove it. Next, install a new one, lubricate the splines and put the gearbox in place. Now the number of manufacturers who produce clutch kits for domestic cars is simply huge.

I need advice and help friends. I installed a clutch from Shniva, Valeo. The jamb came out - it feels like the gears are not engaged, I can’t get into a single gear. I do not know what to do ?
why is Shnivskoye twice as large? The only difference is the flywheel and the price...
clutch 21213 — 2800r, shniva — 5600r (original Valeo 826474) + 2000rflywheel
I missed something else - the transition to shnivya seems to be something else small. Prices are in rubles, but the ratio is visible.
PS Here is a link to Niva-Fak, the shnivy also has a different rod, read it in general. www.niva-faq.msk.ru/tehni…transmis/scepl/sc2123.htm
Thank you, I have a ShNiva - just a flywheel, basket, disc and release, nothing else is needed!
did you give me the price for 213 Valeo like Shnivskoye or Ketai and other VIS?
Not at all). The price was based on the fact that it comes from the factory in stock. The 213rd one comes with the usual pelvic (was) the usual AvtoTaz, I don’t know who makes it. And for shniv, the factory one is immediately valeo.
wow! You can compare within the same manufacturer!)
In this case, the comparison is correct - the prices of factory kits.
By the way, it’s not the usual TAZ that goes to Niva 21213, but Nivovskoe! different basket
Hello, we've arrived, do you think the Niva is not a TAZ? Everyone knows how to read that “Driven disk 21213 is an ugly hybrid of the 2108 hub, the load-bearing part of the original design and 2110 linings. We wanted the best, but it turned out as always. The result is a weak hub (there is a risk of broken damper springs flying out and rubbing surfaces scuffing) and narrow linings (inner diameter 140 mm, outer diameter 200, just like a penny, only the holes for the rivets are located differently). But the basket is the same, 2121, with a wide pressure plate.”
By “ordinary basin” in relation to the Niva spare parts they often mean a comparison with the classics... which is a hybrid - I don’t know, I know that there is a clutch kit for 2106 (2101 is almost impossible to find) and there is one for 2121...
It will be useful: High pressure fuel pump for diesel engine
Dear, TAZ in the usual sense is the Tolyatti Auto Plant. And the Niva will be known to you as 80% classic. What are you arguing about?
not 80% - don’t argue with the Niva because many people break down because it is 80% classic, but who drives the Niva from the Nivovsky spare parts and doesn’t have a soaring brain...
and read carefully about the pelvis in the last comment
I haven’t heard more nonsense, since you decided to troll me, justify it with examples. I was in Tolyatti two weeks ago, it’s a pity that we didn’t have this conversation then. We'd have a laugh with the boys.
I gave you an example - good luck with the boys!
read together with the boys, there is no need to send me photos and videos of your sadly surprised faces!
Sent accordions, chewed a hundred times. Think about the specifics, and I'm off to the garage to change the transmission on a pickup truck)) Have a good day
that's it - chewed 100 times and I chew 101
I see no point in exchanging words. One more off-topic comment and off to the bathroom. You are engaged in chatter, poking at sources that are known. You're trying to pass for smart. If you are really interested in the Niva, its appearance and formation, the history of its creation, read the three-volume book about VAZ veterans “The Flame of High Thought.” The book describes how, on the instructions of the party, for the needs of agriculture, the task was received to create a Niva using the components and assemblies of a Lada. There are only a few unique spare parts in the field. The brightest ones are the body and the RK. The rest is variations.
And when we log into your account, we see “Attention! This user indicated that he does not understand Russian.” I'm really doing something stupid, trying to explain something in Russian to a person who doesn't understand Russian. I don’t want to feed the troll and rant anymore. Cook yourself.
our Niva, these are not the Niva that are described in the book - I read the book and really liked it...
How to remove the gearbox on a VAZ 2121 Niva
The basket looks like a steel circle with a bulge. The design of the device contains release elements, which, when the clutch is engaged, act on the driven disk. These elements are driven by a release bearing, which operates through human mechanical action.
The driven disk has the shape of a round base, consisting of friction linings. This disc is a torque transmitter. It connects directly to the flywheel of the Chevy Niva engine.
Clutch replacement Niva 21214 repair
In normal mode, while the car is moving, the disc is engaged with the flywheel, and they rotate together. When you press the clutch pedal, the disc is acted upon by the release elements of the basket (petals), which move it away from the flywheel. At this time, the torque on the gearbox shaft disappears and the transition to the next gear can be made.
The bearing is an important part that performs the function of squeezing the basket elements. Let's take a closer look at this element. Releaser on Niva Chevrolet: It presses the driven disk against the flywheel when acting on the basket.
The diameter of the device is comparable to the release springs of the basket. The bearing is located on the input shaft of the direct transmission box, only it is attached not to the axle, but to the protective base.
When the driver presses the clutch pedal, the bearing acts on the basket, driving its release elements - the petals. The petals weaken the pressure of the disk against the flywheel, thereby stopping it from rotating.
These bearings come in the following types: The Chevy Niva uses a roller type release bearing. The principle of operation is based on a mechanical effect on the body of the element, which, in turn, influences the basket and its petals.
Characteristics of motor 21213
The requirements for an SUV engine at the time of design were:
- increase power and torque, at least at medium speeds;
- ensure acceptable fuel consumption within 12 l/100 km;
- provide a basis for injection modification in the future.
