1. Add oil to the clutch oil pipe. Replace the clutch oil.
2. Adjust the free stroke of the clutch. If the free stroke of the clutch is too large, the distance of the clutch pressure plate moving backward is not enough, which will cause the clutch plate and can not be completely separated from the engine.
3. Replace the clutch plate with a new one. If the clutch plate is excessively worn, the wear of the release bearing and the diaphragm will not be on the same plane.
4. Replace the clutch return spring. The return force of the clutch is provided by the clutch return spring. If the return force of the return spring is insufficient, the clutch will not be completely disengaged, and the vehicle will always be in a semi linkage state.
