Failure phenomenon Possible reason Failure elimination

1. Transmission gear oil too much Replace the bearing

2. The sychronizer not working normally Replace the synchronizer
3. Mixture of different oil Check and replace
Transmission too hot
4. The clearance is too small (bearing, gear
Adjust the clutch
and relative moving part)

5. The moving parts are badly worn (bearing,
Use the specified grade of lubricant
gear, etc.)

1. Bearing worn or broken Replace the bearing
2. The sychronizer not working normally Replace the synchronizer
Transmission hard to
3. Shifting fork deformed or broken Check, adjust or replace

4. The clutch separates abnormally Adjust the clutch

5. Lubricant viscosity too high Use the specified grade of lubricant
1. Clutch reason: the friction plate is slipped. Check, repair or replace the friction plate.

2. The transmission cannot be shifted and
stays at neutral position: shifting ball broken, Replace the broken part
No dynamic output
joy stick invalid, shifting shaft stuck

3. At a certain gear: second shaft cracked and Dismount the transmission and replace the
flange broken broken part

1. A gear is lost (the gearshift is normal): the
puling cable is broken, the shifting fork or Repair or replace the worn parts in the shift
shifting block is damaged, the synchronizer is selector mechanism
damaged, and the gear selector is defective.
2. Stuck at a certain gear; second shaft broken,
needle bearing burnt and ejector pad jumping Repair or replace the broken parts
No gear position out

3. Shifting mechanism failure, not possible to Repair or replace the worn parts of shifting
shift mechanism

4. At a certain gear, the synchronizer is stuck Replace the synchronizer assembly

5. The parts of synchronizer or joint sleeve are
Replace the broken part
