What are the Ideas And Methods for Troubleshooting Common Clutch Faults?

During the use of a car, it is necessary to frequently step on and release the clutch pedal to separate and engage the clutch. Therefore, the technical condition of the clutch will gradually deteriorate with the increase in the mileage of the car. Abnormal phenomena such as noise and jitter make the clutch unable to work normally. In order to ensure the smooth engagement and separation of the engine and the transmission, the malfunction of the clutch should be diagnosed in time, the cause of the malfunction should be found out and the malfunction should be eliminated. As a Lifan Rear Bumper Wholesale, share with you.

1. Clutch slippage troubleshooting

Trouble phenomenon:

① Clutch slip refers to that when the clutch is engaged, the clutch plate slips between the pressure plate and the flywheel, and the clutch slip shows that the car is difficult to start;

② The speed of the car cannot increase with the increase of the engine speed during the driving process, and it feels weak to drive;

③ When driving uphill with full load, you feel the power is insufficient, and you can smell the burnt smell of the clutch friction plate.

Failure analysis:

When the vehicle is at a standstill, first tighten the parking brake and depress the clutch pedal, then start the engine. At this time, manipulate the transmission shift mechanism, engage "forward 1st gear", and gradually loosen the clutch pedal until it is completely released. During this operation, Properly increase the throttle to increase the output power of the engine. If you feel that the body is sinking and the engine stalls, it means that the clutch is working normally, otherwise, it means that the clutch is slipping.

troubleshooting:

The root cause of clutch slip is that the pressure plate cannot be firmly pressed on the driven plate friction plate, or the friction coefficient of the friction plate is too small, which makes the clutch friction torque seriously insufficient. The specific reasons and troubleshooting methods areas follows:

① If the clutch control system is improperly adjusted, check and adjust the clutch pedal stroke according to regulations;

② The friction plate of the driven disc is severely worn, which weakens the pressing force of the diaphragm spring, so that the torque that the engine should output cannot be completely transmitted to the transmission, and the clutch slips when the car is uphill or accelerating. At this time, the clutch friction plate should be replaced;

③ If there are oil stains on the friction plate, remove the oil stains on the friction plate, pressure plate and flywheel, and then find out the source of the oil stain and eliminate the fault;

④ The friction plate of the driven disk is burnt, hardened or exposed rivets, the friction plate should be replaced;

⑤ The diaphragm spring has insufficient elastic force, deformed or damaged, and should be replaced;

⑥ The pressure plate, flywheel, and driven plate are deformed and should be repaired or replaced;

⑦ The friction plate is severely worn and the clutch slips, sometimes caused by improper operation. Since the diaphragm spring release finger of the clutch is often engaged with the release bearing, the clutch pedal has no idle stroke. Therefore, pay special attention to using fewer half-foot clutches during operation. So as to prevent the clutch from slipping and wearing.
