7.8. Search and elimination of malfunctions

Probable cause

Elimination method

Coupling pro-slipping

• The car is not dispersed at increase in frequency of rotation of a cranked shaft of the engine

• Insufficient speed of the car

• Insufficient capacity on liftings
  1. Insufficient gap of a pedal of coupling
  2. Contamination of a hydraulic drive of coupling
  3. Excessive wear of a disk of coupling
  4. Disk jamming on shlitsa of primary shaft or oil on frictional slips
  5. The disk or flywheel is damaged press
  6. The diafragmenny spring is weakened or broken
  1. Adjust a gap of a pedal of coupling
  2. Clear or replace details
  3. Replace a coupling disk
  4. Replace a coupling disk
  5. Replace press a disk or a flywheel
  6. Replace press a disk
Gear shifting (noise of gear wheels at gear shifting) is complicated
  1. Excessive gap of a pedal of coupling
  2. Leakage of liquid from a hydraulic drive of coupling
