On a UAZ Patriot SUV, a mechanical unit such as the clutch is one of the most vulnerable components of the vehicle. But this does not mean at all that Patriot owners are doomed to periodic repair work and replacement of the components of this unit. The problem, first of all, lies in the nature of the operation of this unit, as well as its correct regulation. In our material we will consider the principle of adjusting the clutch on a car, as well as the main features of the working process.
When adjustment is needed
The clutch on the UAZ Patriot, in fact, as on all modern cars, is an important component, if it is faulty, it is not possible to operate the vehicle. Over time, the parts of this unit not only become unusable, but also require adjustment. If you properly operate the car and its clutch, then this unit will last up to 60-80 thousand kilometers. The only condition for proper operation of the system is the prevention and adjustment of this mechanism, which must be carried out annually or every 20 thousand kilometers.
The need to adjust this unit also arises when the clutch slips, when noise or jerking occurs when the pedal is depressed, as well as when the pedal has little free play. In these cases, you should definitely put the car in for repairs and carry out preventive actions to find and eliminate the causes of such defects.
The essence of regulating this unit is to adjust the amount of full pedal travel. The pedal's free play is the distance it travels without resistance. On this car there is no way to adjust the free play; it is obtained structurally and should be approximately 8-30 mm.
The main signs that the clutch needs adjustment are the following:
In the article on how to adjust the clutch on a Patriot, you will learn all the intricacies of replacing and adjusting the UAZ Patriot clutch in normal garage conditions. In what cases is the clutch replaced, what can it be connected with?
This material reveals such topics as the principle of operation, as well as types of clutch and their advantages on Patriots, what parts are included in the clutch mechanism and operating features. Also, why do you need to adjust the UAZ clutch, detailed photos and video instructions for adjusting the clutch and adjusting the UAZ Patriot clutch sensor and malfunction errors. After this, you can safely go and make a diagnostic card for your car.

How did you decide in the end? After replacing the GCS, the same symptoms. The clutch grabs close to the floor
Greetings. No changes so far, that's how I drive.
What if the rod is extended to the rcs? What will the experts say? How long can it be extended?
I have the same symptoms. It's hard to pull the first one out when it's cold.
you put the giblets from an old UAZ or gas and everything will be fine with squeezing
I have the same thing with the gears engaged, it doesn’t bother me much
Lubrication also helps. Hole in the clutch housing and forward) but still a little will remain. It will be much better.
I read about this, this is how the release bearing is lubricated. Right? There are different symptoms. I have an entry in my bookmarks www.drive2.ru/l/490474546038571405/ There is a bearing whistle.
No, there is no whistle. It is believed that the splines of the shaft and disk are smeared, as well as where the bearing coupling itself moves.
Did you increase the length of the rod and adjust the pedal end? Does Hz completely return to “0”?
As I understand it, the limit switch does not need to be adjusted, because... it opens at the very first moment of pressing the pedal and basically signals that the pedal is pressed. And I'm interested in the end of the move. “0” GCS I don’t know where to look, I can’t see it from under the hood, or from the interior either.
And you remove the limit switch completely and you will see, and only then move the limit switch to the desired position
We've already written about the distance. The first one in motion on any car will be difficult to engage until the synchronizers accelerate the input shaft to the desired speed. Switching with over-throttle solves the problem. Usually I switch it down if necessary.
Perhaps this explains everything. I'm measuring the distance.
Does the back one fit well?
There are no problems with the rear.
health. I also did something like this the other day. this is called adjusting the UAZ Patriot clutch. The pedal free play should be 8-30mm. The full stroke of the pedal should be 15+-2 cm. It is adjusted with the nuts on the GCS pusher.
Which nuts are the ones I have in the second photo, or are there more?
On a UAZ Patriot SUV, a mechanical unit such as the clutch is one of the most vulnerable components of the vehicle. But this does not mean at all that Patriot owners are doomed to periodic repair work and replacement of the components of this unit. The problem, first of all, lies in the nature of the operation of this unit, as well as its correct regulation. In our material we will consider the principle of adjusting the clutch on a car, as well as the main features of the working process.
Principle of operation
UAZ Patriot cars have the following type of clutch: single-disk with a centrally located diaphragm spring. By the type of friction it is dry, by the mode of activation it is constantly closed. Diaphragm clutch is also called petal clutch. This type is also used in other UAZ models: 3741 “loaf”, SUVs 469, 3151. Petal is also used for cars of other brands.
It consists of the following parts:
- pressure disk (basket),
- clutch disc (driven),
- release bearing,
- release bearing drive fork,
- drive system,
- off pedal.
The pressure plate is housed in a stamped steel housing, bolted to the engine flywheel. The driven disk is clamped by a spring, it is located between the flywheel and the pressure plate. During operation, the closed type bearing does not require lubrication.
clutch release drive on UAZ Patriot vehicles Its composition:
The purpose of the drive is to transmit force from the pedal to the fork. When the pedal is applied, a piston located in the master cylinder moves and forces fluid through a pipeline into the slave cylinder. A piston placed in the slave cylinder acts on the clutch release fork. Then the fork moves the bearing along the guide. The bearing, in turn, acts on the diaphragm spring, which stops pressing the pressure plate against the flywheel. The clutch switches off.
Paddle clutch has the following advantages:
- less weight of parts,
- smaller part size,
- long service life of parts before the next maintenance,
- improved functionality,
- easier maintenance.
Features of operation and operation of the UAZ clutch drive.
When the clutch pedal is abruptly released, a single knock is possible due to the choice of lateral clearances in the toothed connections of the gears, splined connections and in the gearbox synchronizers.
Maintenance
Get regular maintenance
To service the clutch basket of UAZ vehicles with a diaphragm spring, professional skills are not required. First of all, the clutch must be kept clean, regularly removing any dirt that has arisen. Bolted connections need to be tightened periodically.
It is necessary to constantly check the volume of working fluid that is in the master cylinder. It should be about 1.5 centimeters, but below the top edge of the cylinder. In this case, the tank is filled using the installed mesh filter. It is used to prevent the entry of unnecessary objects and substances. Typically, the UAZ 469 clutch slave cylinder does not require any additional, special manipulations.
Stroke adjustment
Need for adjustment
Adjustment of the pusher pitch in the clutch slave cylinder is carried out to ensure that the clutch performs its tasks correctly. If the adjustment is incorrect, two types of problems can occur.

In the first case, incomplete pressing of the pressure plate against the driven one may occur. This happens when the free play of the rod is completely absent or it is less than normal. In this case, clutch slipping will occur, which will inevitably lead to wear of the components.
In another case, when the free play is greater than necessary, a phenomenon such as incomplete disengagement of the clutch will be observed. In this case, the driver of the SUV will experience problems with shifting gears, they will turn on poorly, or stop turning on completely. This entails increased wear on the synchronizer blocking rings.
At this point we should summarize and note that it is very important to monitor the serviceability of the clutch and add brake fluid to the reservoir on time.
A clutch malfunction on a UAZ Patriot SUV can have serious consequences.
We recommend that you begin adjusting the cylinder rod pitch by cleaning the threads of the adjusting nuts. To do this, it is necessary to lubricate the threads and nuts with a special lubricant such as WD-40. After this, we proceed to the actual process:
One key secures the adjusting nut on this element, and the second one loosens the lock nut.
Using a hand vice or an “8” wrench, it is necessary to clamp the end of the pusher from turning it. When the rod is fixed, it is necessary to unscrew the locknut a few turns back.
After this, the free pitch is adjusted, bringing it to normal.
The locknut returns to its original position and fixes the stroke of the rod.
At the end of the work, it is necessary to check the presence of a free step. If it is within the normalized range, then everything was done correctly. This process is not labor-intensive and can be done with your own hands at no extra cost.
Sometimes it is necessary to adjust the UAZ clutch, which consists of changing the position of the clutch pedal. For this purpose, the main cylinder has an adjustment unit.
Adjusting the full travel of the UAZ clutch pedal.
The position of the clutch release pedal and its full travel is regulated by changing the length of the pusher of the clutch master cylinder. To do this, loosen the nut of the pusher adjustment unit, disconnect the pusher fork from the pedal and turn it in the desired direction to achieve the required result.
The full pedal travel for clutching with a diaphragm-type pressure spring must be within:
— For cars of the UAZ-3160 and UAZ-3162 family: 130-170 millimeters.
— For cars of the UAZ Patriot family until 2007: 130-170 millimeters.
— For cars of the UAZ Patriot family after 2007: 120-140 millimeters.
— For cars of the UAZ-3741, 3962, 3909, 2206, 3303 family of carriage layout: 180-220 millimeters.
And for UAZ vehicles with clutches with pressure springs and release levers -165-205 mm. More precisely, the amount of free play of the clutch pedal can be clarified in the operating manual for a specific vehicle.
Adjusting the free play of the clutch pedal UAZ.
The free travel of the clutch pedal with a diaphragm-type pressure spring in the range of 5-30 mm is ensured by the clutch design itself and is not adjustable. Adjusting the free travel of the clutch release pedal with pressure springs and pull-out levers, which can be installed on some UAZ vehicles with a UMZ-421 engine, is done by changing the length of the working cylinder pusher in the following order:
Removing air from the drive hydraulic system
Quite rarely, but it happens that the clutch needs bleeding. This can be understood from the fact that it does not turn off completely and the pedal is not pressed so softly. Bleeding is the removal of air from the hydraulic system. This process is carried out when the liquid in the tank is at a normal level.
During work, it is necessary to remove the rubber cap located on the bypass valve and install a hose in this place. Then the other end of the hose is lowered into a 0.5 liter container containing brake fluid in a ratio of 1:3.
Afterwards, the bypass valve must be turned one turn while another person presses the pedal all the way. You need to press the pedal until the air bubbles stop being released. The bypass valve must then be tightly closed.
Adjusting the UAZ Patriot clutch sensor (error 0704)
I got tired of error 07074 on the BC, over the weekend I missed misfires because of it, on a healthy engine this indicates bad fuel. In this case, it is confirmed that the Honda from the column
