- 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
Adjust
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
