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
|
- Insufficient gap of a pedal of coupling
- Contamination of a hydraulic drive of coupling
- Excessive wear of a disk of coupling
- Disk jamming on shlitsa of primary shaft or oil on frictional slips
- The disk or flywheel is damaged press
- The diafragmenny spring is weakened or broken
|
- Adjust a gap of a pedal of coupling
- Clear or replace details
- Replace a coupling disk
- Replace a coupling disk
- Replace press a disk or a flywheel
- Replace press a disk
|
|
Gear shifting (noise of gear wheels at gear shifting) is complicated
|
- Excessive gap of a pedal of coupling
- Leakage of liquid from a hydraulic drive of coupling
- Wear or corrosion of a disk of coupling
- Excessive distortion of a disk of coupling
|
- Adjust a gap of a pedal of coupling
- Define a place of leak and eliminate it

Coupling noise
|
|
When coupling is not used
|
- Insufficient gap of a pedal of coupling
- Excessive wear of a disk of coupling
|
- Adjust a gap of a pedal of coupling

|
|
Emergence of noise after coupling separation
|
- Wear or damage of the bearing of switching off of coupling
|
- Replace the bearing of switching off of coupling
|
|
Emergence of noise at coupling separation
|
- Lack of greasing on a surface of the basic plug
- In an inadequate way are established the bearing of switching off of coupling
|
- Grease a surface of the basic plug
- Repair
|
|

|
- The directing plug is damaged
|
- Replace directing plug
|
|
The pedal of coupling is pressed hardly
|
- There is not enough greasing of a pedal of coupling
- There is not enough greasing on shlitsa of a disk of coupling
- There is not enough greasing on the lever of a shaft of switching off of coupling
- There is not enough greasing on a forward cover of bearing knot
