|  Symptom   | 
 Possible reason   | 
| 
The pedal of coupling fails to a floor practically without resistance or with very insignificant resistance  
 | 
The main or executive cylinder is faulty (see the Head Stsepleniye).   | 
| Leak of hydraulic liquid in lines takes place (see the Head Stsepleniye).   | 
| Tightness of nipple connections of a hydraulic path is broken (see the Head Stsepleniye).   | 
| Hydraulic liquid in the tank came to an end (see the Head Routine maintenance of the car).   | 
| If liquid traces in a boot of the main cylinder take place, then the back epiploon of the main cylinder is damaged (see the Head Stsepleniye).   | 
| The release bearing or fork of switching off of coupling is damaged (see the Head Stsepleniye).   | 
| 
On a cover of a boot of the main cylinder and around a pedal of coupling traces of hydraulic liquid take place 
 | 
The back epiploon of the main cylinder is damaged (see the Head Stsepleniye).   | 
| 
Traces of liquid take place on the executive cylinder 
 | 
The epiploon of a plunger of the executive cylinder is damaged (see the Head Stsepleniye).   | 
| 
 When squeezing a pedal of coupling the feeling of softness of the course takes place  
 | 
 Air got to hydraulic system (see the Head Stsepleniye).   | 
| 
 There is no coupling switching off (it is impossible to choose transfer)  
 | 
 Transmission is faulty (see the Head the Manual Box of Gear Shifting (MBGS)).   | 
|  The clutch plate is faulty (see the Head Stsepleniye).   | 
|  The release bearing and fork of switching off of coupling are incorrectly assembled (see the Head Stsepleniye).   | 
|  The coupling basket disk is faulty press (see the Head Stsepleniye).   | 
|  Bolts of fastening of a basket of coupling to a flywheel weakened (see the Head Stsepleniye).   | 
| 
 Coupling revolves (turns of the engine raise without increase in speed of the movement of the car)  
 | 
 Frictional overlays of the conducted disk are excessively worn-out (see the Head Stsepleniye).   | 
|  Frictional overlays of the conducted disk are polluted by oil owing to leaks through a back epiploon of a bent shaft (see the Head Stsepleniye).   | 
|  The diaphragm spring weakened (see the Head Stsepleniye).   | 
|  The conducted clutch plate is overheated (see the Head Stsepleniye).   | 
| 
 At inclusion of coupling there is a vibration  
 | 
 Frictional overlays of the conducted disk are polluted by oil or lubricant, zapolirovana to gloss or burned (see the Head Stsepleniye).   | 
|  Support of the power unit are worn-out, or their fastening weakened (see Chapters the Engine and the Manual Box of Gear Shifting (MBGS)).   | 
|  Vents of a main shaft of the transmission or nave of the conducted disk are worn-out (see the Head Stsepleniye).   | 
|  The disk or flywheel is deformed press (see the Head Stsepleniye).   | 
| 
 Around coupling there are extraneous noises  
 | 
 The coupling switching off fork is incorrectly established (see the Head Couplingеof ).   | 
|  The release bearing of coupling is faulty (see the Head Stsepleniye).   | 
| 
 The coupling pedal after an otpuskaniye remains squeezed out to a floor  
 | 
 The fork of switching off of coupling is jammed in a casing (see the Head Stsepleniye).   | 
|  The release bearing or fork of switching off of coupling is broken (see the Head Stsepleniye).   | 
| 
 Squeezing of a pedal of coupling requires too big effort  
 | 
 The coupling switching off fork is jammed in a casing (see the Head Stsepleniye).   | 
|  The disk is faulty press (see the Head Stsepleniye).   | 
|  The main or executive cylinders of coupling are installed not that standard size (see the Head Stsepleniye).   |
