Replacing the clutch in a Gazelle car is required quite often, since it is a vulnerable spot. The machine is mainly intended for business, the components and assemblies of which always work in a loaded mode. Therefore, the service life of the parts is limited; on average, the clutch requires replacement every 50–70 thousand kilometers. As a rule, it changes as a set (pressure plate, driven plate, release bearing).
You can do it yourself by replacing the disk or the entire set. For example, take a Gazelle with a ZMZ 40524 engine (it is from the ZMZ 406 engine family).
We put the car on the pit and first of all remove the gearshift lever. Before removing the lever, it must be set to neutral. Lift up the rubber casing.
Find the flare nut, turn it off and pull out the lever.
We make marks on the propeller shaft and the rear axle shank.
Marks are made in order to put the shaft in the same position during assembly. If the "gimbal" is not placed according to the marks, vibration may occur.
Then we unscrew the gearbox traverse (8 bolts at the edges) and pull out the shaft. Before removing the propeller shaft, it is advisable to drain the oil from the gearbox.
We unscrew the fastening of the clutch slave cylinder, remove the cylinder to the side, remove the plug.
We dismantle the clutch housing ("bell"), first the lower aluminum crankcase amplifier, then the crankcase itself.
We unscrew the six bolts on the basket. Everything is sorted out.
We take a new set - basket, disc, release bearing, and start assembling. In order to install the gearbox without any problems, the driven disc must be centered, and then the “basket” bolts must be tightened. The bolts must be tightened evenly in a circle, and not immediately on one side. For alignment, you can use a special mandrel or any input shaft of the Gazel or Volgovskaya gearbox. The shaft will fit even from a 4-speed gearbox.
Then we collect everything further in the reverse order. It is convenient to immediately put the release bearing on the flange of the input shaft of the box, having previously laid a sponge soaked in thick grease under it. The sponge can be soaked in gear oil.
To replace the fork, unscrew the two bolts of the clutch slave cylinder (RCS), the cylinder on the hose is retracted to the side. We take out the old plug and install a new one. It is necessary to ensure that the fork falls on the special ebbs of the release bearing clutch, otherwise there will be no normal squeezing of the clutch pedal.
Having installed a new plug, we squeeze the RCS through the rod, bring it to the attachment points, fix the cylinder with bolts. Of course, the clutch hose can be unscrewed and it will be easier to install the RCS, but then you have to bleed the clutch. We have described the replacement of the plug in the simplest and most optimal way.
VIDEO The replacement of the working or master cylinder of the clutch with a Gazelle, as well as other parts, allows to prevent the failure of a car.It is important to diagnose and repair the vehicle in a timely manner, replace, if necessary, the clutch kit and other components. In the future, this will help to avoid breakdowns on the highway and road accidents.
Diagram of the clutch device on the Gazelle
To transmit torque to the driving wheels of the vehicle from the crankshaft of the motor, a transmission is provided, since the direct transmission of torque from the motor to the wheels is unprofitable. The car will not be able to go without the clutch, and the operation of the power unit itself will be ineffective.
For convenient operation of the power plant, the torque taken from the crankshaft must first be changed in the gearbox (gearbox). After that, it changes over to the driving axle. Since shifting gears causes the transmission gears to rotate, which forcefully hit each other, changing gears can be difficult. With a permanent connection of the box to the power unit, to completely stop the vehicle, it will be necessary to stop the motor as well.
Clutch work in a Gazelle car
The principle of its operation is the same for any car brand. It eliminates the possibility of rapid wear of units and parts that connect the power plant and transmission.
The clutch pressure plate, attached to the housing, presses the clutch disc against the flywheel. The disc hub attached to the input shaft must be able to move freely along it. The hub housing is equipped with damper springs that act as vibration dampers and ensure smooth running.
Carrying out minor repairs, replacing the clutch fork, including adjusting its pedal, will not require much time. If you have quality parts, for example, produced by Sachs or Kraft, it will take only about 2 hours to replace.
The Gazelle clutch requires proper handling and timely replacement as a result of frequent repairs and adjustments. Replacing the entire assembly is not necessary in every case. The stages of the replacement depend on the brand of the Gazelle car, determined by the engine, for example, Cummins ZMZ 406 and 405, etc.
In some cases, it is necessary to solve the problem with the change of the gearbox detected as a result of the system diagnostics.
Sometimes it may be necessary to check the entire pipeline, as well as bleed the system. The cause of the violation may be damage to the reservoir included in the clutch kit for the Gazelle.
Replacing the clutch may be required as a result of intensive operation of the Gazelle car and if the following errors occur:
The process of replacing the clutch on a Gazelle
Low quality parts were used in the assembly.
The clutch pedal was kept pressed during the movement, which is strictly prohibited by the manufacturers.
"Jerks" were made at high speeds.
To increase the service life of the Gazelle clutch, the installation of parts manufactured by the manufacturing company Sachs will be reliable. They are recommended by the manufacturer because they are reliable and have been tested for compatibility with the transmission and engine. Under the same conditions, a Sachs clutch will last longer than a third-party clutch.The common analogue of the Gazelle Business clutch, manufactured by Kraft, has not only good quality, but also a fairly low percentage of defects. The most common reasons for Gazelle owners to contact service services are malfunctions associated with the clutch release drive.
leak of the main cylinder of the Gazelle clutch (GTS);
leaving the brake fluid from the GCS reservoir;
leakage of the clutch slave cylinder (RCS);
bypassing the HCC cuff;
bent or dropped piston rod of the working cylinder, etc.
Careful operation of the car does not imply any "jerks", but only the presence of conditions that allow you to smoothly get under way and change gears when the car is moving. Most often, clutch replacement is required for trucks. The Gazelle car intended for business requires increased attention to this unit, the elimination of breakdowns in which is often not possible. Since replacing the device does not require removing the motor, you can repair the clutch or install new parts yourself.
noise is heard in the gearbox when the car is moving;
the transmission turns off spontaneously;
changing gears causes various extraneous noises;
gear shifting is difficult.
The clutch is one of the important automotive mechanisms, thanks to which the car has the ability to move smoothly and change gears while driving. Since this unit is constantly and heavily loaded, it often needs to be repaired or completely replaced. This is especially true for vehicles intended for transportation. If we talk about domestic cars, then the leader in the number of clutch breakdowns can be called GAZelle.
Designed for business, it is constantly exposed to high loads, which inevitably affects the clutch, which breaks down with enviable regularity. The most unpleasant thing is that in most cases, the breakdown of this unit cannot be eliminated, which leads to the need to change it completely. You can do this yourself, especially since you do not have to remove the motor.
There are many symptoms that the clutch is not working correctly, and in order to independently determine the need for replacement, you do not need to have special knowledge.
Poor gear shifting.
When changing gears, extraneous noise of any nature appears.
Spontaneous shutdown of gears.
Noise in the box when driving.
If all work is carried out independently, before replacing the clutch with a GAZelle, a little preparatory work is required. First of all, you need to find a room with a lift or a comfortable pit. A set of tools is useful for work - keys and screwdrivers.
Replacing the clutch on a GAZelle with your own hands begins with dismantling work. The car at this time should already be on the pit or lift. At the gear lever, the seal rises and the cap located at its base is turned off. After that, the lever can be pulled out with some effort. Literally everything should be disconnected from it, the “stopachi” wires and the speedometer cable are disconnected from the box. The work in the cockpit is over, you can go down under the car.
All work on replacing the clutch with a GAZelle should be carried out carefully so as not to damage the adjacent units.
The slave cylinder is connected to the starter - first of all, you need to disconnect them. The released cylinder rises up together with the pusher, while the hose does not need to be removed from it. If the clutch fork is replaced with a GAZelle, then the main part of the work can be considered completed, since it became possible to remove it by unscrewing only one bolt. After that, the lower part of the crankcase is removed, the bracket that serves to connect the pipes of the muffler becomes visible - it will need to be removed.
Now you need to remove the box. This can be done by unscrewing its fasteners. It is removed together with the clutch itself. The seals located between the clutch housing and the box are dismantled. Next, you can try to find special marks for alignment on the engine flywheel and pressure casing. They may not be there, then you should apply them yourself. The casing and flywheel are turned away, while it is necessary to gradually turn the crankshaft by hand. This is the stage of replacing the clutch discs with GAZelles - they can be removed through the hatch.
Now the replacement of the GAZelle clutch master cylinder is available, if this is not needed, then it can be simply removed by disconnecting the hose from it and draining the entire composition. True, you will need to disconnect the pusher from the pedal - this is easy to do. Installation of another unit, of course, is carried out in the reverse order. New grease is added to the ball bearing of the input shaft beforehand. When installing the casing, do not forget that the marks are native or applied independently, and must be combined.
At this point, the main stage of work on the independent replacement of the clutch with a GAZelle can be considered complete. But in addition to replacement, adjustment of the GAZelle clutch is also required. A special tool is used to center the disc and crankshaft. It is inserted into the driven disc, which has a special bore, making sure that the tool being used also fits into the bearing bore on the flywheel. How this is done in practice can be seen in the video:
VIDEO
Various facts can become the reasons for the failure of this necessary unit, but most often the following can be distinguished among the reasons for this:
"Jerk" from a place at high speeds;
holding the clutch pedal pressed while driving is strictly prohibited by all car manufacturers;
the initially low quality of the parts used in the assembly.
Separately, it is worth noting the excessively intensive operation, which is so typical for domestic GAZelle cars. Quite often, dissonance in the work of the clutch is introduced by "crooked" mechanics who can install an accidentally oiled disc, which will lead to slippage - in this case, only replacing them will help.
But not in every case it is necessary to change the entire node. Often it is necessary to replace the clutch slave cylinder - this unit also works with fairly high loads. Problems with changing gears or braking are caused by airing the system. In this case, checking the entire pipeline and bleeding the system helps. If the problem returns again, you should pay attention to the tank. It can be damaged quite easily, then replacing the clutch reservoir with a GAZelle will help.
There are few photos - they were carried away by work, there was no time to shoot.

GAZ Gazelle 2008, petrol engine 2.5 l., 123 hp sec., rear-wheel drive, manual transmission - DIY repair
Good evening, my dear, how many came out.
Greetings! 149100 passed.
Hello. How is the grip? walks normally? It's also time to change, so I want to know your opinion. And where did you buy it?
Hello. The clutch is fine, it walks great. So it's worth taking. I took it to Olmi for Shcherbakov. Do not forget to change the support bearing in the flywheel.
A good choice. I put luk after my own, during the second replacement I took valeo, burned myself. I ruined the box (they did not turn on hot gears) As a result, the box was repaired, the clutch was replaced with a luk.
I, too, or Bow or Sachs were advised to bet.
And now I am on the table top on the asphalt near the garage - poems turned out!
Even better on asphalt. It is difficult to find fallen nuts in the grass.
The grip is not bad, who would argue ... Simply, if the disc is more efficient, then, judge for yourself, in what place the disc will work and how long it will last ...
Reasonable. Only the mileage must be large in order for a tangible production to appear.
Did the flywheel print match the new disc?
It didn't even occur to me to check, to be honest. When I changed the link on the VAZ-2111 (my first car), I also did not check it. Moreover, the Sachs clutch was tested and approved by many gazelists.
thousand 50 through my fault, I killed her
I also have a sax for the second time I'm playing it very happy
And how many ran the first time?
Consider my car 2.5 ... 700 kg of cargo and in such wilds ... today I will post pictures ... works with a bang, very satisfied
Sachs is a good choice ... and according to the reviews I set the clutch release correctly ... I get along on the lakes off-road ... good traction is the key to success ... I felt it ... the choice is justified
I have very rare off-road and moderate. But to carry one and a half tons is a common thing. So it's good if you chose the right one.
Sachs has excellent grip and will run a lot. When installing the clutch, you need to use a mandrel (the Saxon comes with a plastic one) or an old input shaft.
We will show you the instructions on how to replace the clutch in a Gazelle Business car with an UMZ 4216 engine. The clutch must be replaced on a lift or inspection pit. Before starting work, put the box in neutral. First of all, we remove the cardan, pre-clean all its mounting bolts with a metal brush, then spray it with WD-40 penetrating grease. We take the cardan out of the box. We unscrew the traverse. Disconnect the speed sensor, rear speed sensor. We unscrew the muffler. When the boxes are slightly lowered, remove the speed lever. We remove the dry sump and we can already see the clutch, assess its condition. In our case, the disc wear is clearly visible, the basket is blue, which means that the clutch was burned somewhere.
Next, we unscrew the box fastening nuts (they are on a turnkey basis for 19), then you can remove it, one person can do this, it is not particularly heavy. It is not necessary to drain the oil. After that, assess the condition of the plug, if necessary, replace it. We take the release bearing, we also assess its condition, for this, twist it, if you hear noise, you need to replace it. We unscrew the basket (6 bolts by 13), before that it is better to put a mark if you decide to leave it and not change it.

Regarding the replacement of the clutch with a Cummins ISF 2.8 (Cummins 2.8). There is almost the same thing, the box is removed in the same way, then the clutch slave cylinder, it is necessary to remove and unscrew the bell completely, then the entire basket will be visible. Also, do not forget that Cummins has its own clutch, from Business it will not work. I can recommend the SACHS clutch, it will certainly not be cheap, but reliable and there will be much less noise and twitching from the gearbox.

VIDEO Remove the clutch housing (see the article - "Removing the clutch housing").
With a core, we mark the relative position of the casing and the flywheel.
1. Keeping the flywheel from turning with a screwdriver or a mounting spade, with a key or a 12 head, unscrew 6 bolts.
2. Remove the drive disc assembly (basket) and the driven disc.
After disassembly, the clutch parts should be rinsed in kerosene and inspected. Cracks, scoring and deep grooves are not allowed on the surface of the drive discs. If available, replace the flywheel and basket assembly. We replace the driven disc with pads worn to rivets, warped, cracked, oiled and burned. The protrusion of the ends of the diaphragm spring blades is controlled using a spacer.
When the ends of the petals are moved 8.5 mm downward, the pressure disc must be at least 1.3 mm apart, otherwise we change the drive disc (basket) assembly.
Any cracks and breaks are not allowed on the crankcase. When assembling, we cover the rubbing surfaces of the forks, couplings, pushers and shaft splines with SHRUS-4 grease.
Install disks in the following sequence
1. Insert the centering mandrel into the engine flywheel bearing.
2. We put the driven disk on it.
3. The disc hub protrudes less on one side than on the other. This side must face the flywheel.
Dismantling the clutch of the car with the engine model ZMZ-402
We carry out the work on a viewing ditch.
The clutch of the GAZ-53 car (Fig. 1) is single-disc, dry with a damper device on the driven disc. Installed in a cast aluminum crankcase 2. The GAZ-53 clutch disc cover is attached to the crankshaft flywheel by six centering (special) bolts. A pressure plate (basket) is placed inside the casing. The rotation of the GAZ-53 clutch basket is transmitted from the flywheel through three protrusions in the disc and entering the casing windows. The torque from the engine to the gearbox is transmitted through the driven disk 3, clamped between the ends of the flywheel 1 and the pressure plate by the force of twelve springs 12.
Fig. 1. GAZ-53 clutch and its drive
Adjustment and maintenance of the GAZ-53 clutch
Caring for the GAZ-53 clutch and its drive consists in periodically lubricating the thrust bearing of the clutch release clutch and in adjusting the drive.
Lubrication of the GAZ-53 clutch release bearing is carried out by a cap oiler 6 located on top of the clutch housing. To do this, squeeze the fully filled cap oiler into it twice. Only the third fill of the oiler will supply grease to the bearing. Adjustment of the GAZ-53 clutch release drive is required if the free travel of the clutch pedal does not correspond to 35 - 45 mm. Adjustment of the amount of free travel of the clutch is made by changing the length of the rod 14. To increase the free travel of the pedal, it is necessary to unscrew the nut 13. Premature wear of the linings, destruction of linings and breakage of the hub of the driven disc along the windows under the springs can be caused, respectively, by movement with the clutch semi-disengaged, switching on at high speed II or 1st gear and non-smooth engagement of the clutch when shifting to third or direct gear and can occur only if the vehicle is used improperly.
GAZ-53 clutch repair
The clutch is removed from the vehicle without removing the engine. To do this, the car is installed on an overpass, lift or inspection pit in order to provide easy access to the clutch from below. The gearbox is removed together with the clutch and the GAZ-53 clutch release bearing. The recoil spring is disconnected from the clutch and the bearing is pressed from the clutch. Unscrew the mounting bolts and remove the stamped lower part of the clutch housing. Check for the presence on the engine flywheel and the casing of the pressure plate (basket) of the GAZ-53 combined marks "O" and, if they are absent, apply them. Gradually loosen the bolts securing the clutch cover to the flywheel, while turning the engine crankshaft. Remove the driven and pressure plates of the clutch from the crankcase through the lower hatch.
Rice. 2. The position of the driven and pressure disks GAZ-53 at the time of their removal
Replace both linings at the same time, as the difference in the thickness of the linings will disrupt the normal operation of the clutch. To remove worn or damaged linings, drill out and carefully knock out the rivets that attach the linings to the leaf springs and disc with a beard.
The surface of the pressure plate and the GAZ-53 flywheel, if there are scuffs and ring marks on them, is corrected by grooving and grinding. The size of the metal layer removed during processing must be such that the thickness of the pressure plate after processing decreases by no more than 1 mm. In this case, during assembly, in order to maintain the pressing force, additional steel washers are installed under the heat-insulating washers, the thickness being equal to the value of the metal removed from the surface of the pressure plate. When assembling the GAZ-53 driven disk, friction linings are riveted. After flaring, tears and cracks on the rivet heads are unacceptable. The end face of all heads of the rivets for fastening the linings is recessed at least 2 mm from the working surface.The riveted head on the disk should be 0.6 - 0.9 mm high, and on the spring plates 0.9 - 1.2 mm, which ensures that the riveted heads are drowned in the holes of the spring plates and the disk when assembling the driven disk. The plates are riveted to the disc with steel rivets with a diameter of 4x5 mm.
Fig. 3. Adjustment of the GAZ-53 clutch release levers
The GAZ-53 clutch disc with new linings is checked for runout of the friction plane. The runout of the disc pads, measured at a radius of 125 mm, is no more than 0.7 mm.
With a larger runout, the disc is straightened using a special mandrel. Then it is subjected to static balancing using special balancing weights. Balanced to the balance of the driven disk no more than 18 gf / cm.
When assembling the basket (pressure plate) of the GAZ-53 clutch, make sure that the marks made during disassembly on the casing 11 (see Fig. 1), the pressure disc 4 and the levers 5 coincide, and the pressure springs 12 are centered on the casing flanges.
To prevent the needles from falling out of the holes in the levers, rubber balls with a diameter of 8.0 - 8.5 mm are installed or the needles are abundantly lubricated with grease (there should be 19 needles in each bearing). After assembly, adjust the position of the heads of the release levers of the support fork. The position of the release levers is adjusted only when the clutch is removed from the car. This cannot be done by car.
If, when assembling the clutch of a GAZ-53 car, the release levers, a casing or a pressure plate were replaced, then static balancing of the pressure plate assembly is performed by drilling metal from the pressure plate bosses, which serve to install the pressure springs.
The drilling depth from the edge of the boss should be no more than 25 mm, including the taper of the drill. The permissible imbalance of the pressure plate is not more than 25 gf / cm. The clutch is installed on the car in the reverse order of removal: before installing the clutch, put lubricant 1-13 into the hole of the ball bearing of the input shaft installed in the flywheel, wipe the friction surface of the flywheel and pressure plate with a piece of clean cloth soaked in gasoline; center the driven disc with respect to the crankshaft axis - a special mandrel is inserted into the spline hole of the driven disc so that its end enters the flywheel ball bearing.
A spare input shaft is also used for this purpose; tighten the bolts securing the casing to the GAZ-53 flywheel evenly (to avoid warping the casing); when installing the clutch release fork, ensure the correct position of the tabs on the flats of the clutch release clutch.
