- Cause of malfunction

Elimination method

The clutch does not disengage completely (the clutch “drives”):

- Increased free play of the clutch pedal (over 55 mm)

Adjust as described in the article - “Removing and installing clutch discs

- Driven disk is deformed

Straighten or replace the drive

- Air got into the hydraulic drive system

Bleed the system

- Parts of the driven disk are destroyed

Replace the drive

- The driven disk hub sticks on the splines of the input shaft

Eliminate the cause of the jam (burrs, dirt, nicks, etc.)

- The release levers of the pressure plate do not lie in the same plane, parallel to the plane of the flywheel

Disassemble the clutch and adjust the position of the release levers

- The clearances in the clutch drive have been increased

Replace worn parts

- The full travel of the clutch pedal is not adjusted


The clutch is not fully engaged when the pedal is released (the clutch “slips”):

- There is no free play in the clutch pedal           

Adjust the clutch release drive

- The pressure plate movement mechanism is stuck

Remove the cause of the jam or replace the drive

- Reduced force or breakage of pressure springs

Replace the compression springs

- Oiling of disks (friction surfaces)

Wash the discs and linings with gasoline and wipe them dry

- Clutch overheating due to prolonged slipping

Allow the clutch to cool

- Clogged compensation hole of the clutch master cylinder

Clean the compensation hole and change the fluid if it is dirty

Inconsistent clutch engagement (with jerking and vibrations):

- Oiling and sticking of disks (friction surfaces)

Replace the friction linings or wash them in gasoline and sand them with fine sandpaper to remove protruding irregularities.

Use the same sandpaper to clean the surfaces of the flywheel and pressure plate. Eliminate the cause of the oiling.

- Wear of friction linings to rivets

Replace the friction linings

- Pressure plate release springs do not lie in the same plane parallel to the plane of the flywheel

Disassemble the clutch and adjust the position of the release levers

Clutch noise (when pressing the pedal):

- The clutch bearing is worn out or lacks lubrication

Lubricate the bearing. If the noise continues, replace the bearing

Clutch pedal does not stay in the up position:

- Breakage of the release spring

Replace the spring
