- Cause of malfunction

Remedy

Clutch does not fully disengage (clutch "drives"):

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

Adjust as described in "Removal and installation of clutch discs UAZ-3151 »

- Deformed driven disk

Repair or replace disc

- Air got into the hydraulic drive system

Bleed the system

- Parts of the driven disk are destroyed

Replace disc

- The hub of the driven disk is stuck on the splines of the input shaft

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

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

Disassemble the clutch and adjust the release levers

- Increased gaps in the clutch drive

Replace worn parts

- The full travel of the clutch pedal has not been adjusted

Adjust

Clutch does not fully engage when the pedal is released (clutch slips):

- There is no free play of the clutch pedal

Adjust the clutch release actuator

- The mechanism for moving the pressure plate is stuck

Remove the cause of the jam or replace the disc

- Reduced force or broken pressure springs

Replace pressure springs

- Oiling discs (friction surfaces)

Rinse the rims and pads with gasoline and wipe them dry

- Clutch overheating due to prolonged slipping

Let the clutch cool down

- Clogging of the compensation hole of the clutch release master cylinder

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

Unsmooth clutch engagement (with jerks and vibrations):

- Lubrication and sticking of discs (friction surfaces)

Replace friction linings or wash them in gasoline and sand with fine sandpaper to remove protruding bumps. Clean the surfaces of the flywheel and pressure plate with the same sandpaper. Eliminate the cause of oiling.

- Wear of friction linings to rivets

Replace friction linings

- Do not lie in the same plane parallel to the plane of the flywheel, the release springs of the pressure plate

Disassemble the clutch and adjust the release levers

Clutch noise (when depressing the pedal):

- Clutch bearing worn or out of lubrication

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

Clutch pedal not holding up:

- Broken release spring

Replace the spring
