Frequently encountered failures in the clutch system

After learning how they are working, let’s look at the faults that are often encountered in clutch systems.

Clutch slippage and vehicle trembling are two common failure phenomena in clutch systems. Through two forms below, the fault phenomenon, possible causes and solutions can be listed for everyone, so that we can prevent it in advance and improve the operating habits or problems.

Clutch slip

Symptom: The clutch plate is worn or ablated.
Possible cause: Frequent use of semi-coupling operation causes excessive wear of the clutch plate.
Maintenance method: pay attention to usage habits under standard load conditions.

Symptom: The surface of the clutch is burnt or the surface of the platen is blue.
Possible causes: Under heavy overspeed and heavy load conditions, the clutch is frequently used or often in a semi-coupling state.
Maintenance method: pay attention to usage habits under standard load conditions.

Symptom: The free travel distance of the clutch pedal is too small.
Possible cause: Pre-energizing force on the separation spring of the diaphragm spring.
Inspection method: adjust the pedal free distance and separate the gap between the bearing and the diaphragm.

Symptom: The frictional contact surface of the clutch assembly is oily.
Possible cause: The transmission input shaft oil seal fails and leaking oil.
Inspection method: replace the transmission oil seal.

Trembling when starting

Possible cause: The pressure plate or flywheel surface is not flat.
Inspection method: check and replace damaged parts.

Possible cause: The pressure plate separation refers to uneven force, bias, and softness.
Inspection method: check the pressure plate or separate bearing, replace if damaged.

Possible cause: The clutch pedal is not fully returned.
Inspection method: Check the clutch pedal mechanism to see if there is any fault.

Possible cause: Diaphragm breaks.
Inspection method: replace the pressure plate.

Possible reasons: The second gear starts, not operated properly. Maintenance method: pay attention to operating habits.
