Basic information

Solve your problems in the following areas:
1. Oil leakage, clutch does not separate. It affects the normal driving of the vehicle, increases the fuel consumption, and poses a safety hazard. Quick judgment method: Step on the clutch on the car and see if the branch pump is moving. If it does not move, remove the oil pipe connecting the sub pump and see if there is no oil. If there is no oil, it is the problem of the master pump. Oil, that’s the problem with the sub-pump.
2. When the driver depresses the clutch pedal, the push rod pushes the piston of the master cylinder to increase the oil pressure, and enters the sub-pump through the hose, forcing the pull-rod of the sub-pump to push the release fork and push the release bearing forward. When the driver releases the clutch pedal, the hydraulic pressure is released, the release fork gradually returns to its original position under the action of the return spring, and the clutch is in the engaged state again.
