What are the causes of abnormal noise from the clutch pedal?
1 Answers
The main causes of abnormal noise from the clutch pedal are: wear or jamming of the release bearing; looseness of the separation lever pins and pin holes due to wear; looseness of the drive pins and pin holes due to wear. The specific details are as follows: 1. When judging the noise from the clutch, gently press the clutch pedal to make the release bearing contact the separation lever. The noise heard at this time is from the release bearing, which may be caused by insufficient lubrication or looseness and damage of the bearing. 2. Continuously press and release the clutch pedal. If noise occurs when the clutch is engaged or disengaged, the severity of the noise can help determine whether it is due to wear and looseness of the separation lever pin holes and support pins, or loosening of the rivets on the driven disc assembly, or failure of the damper. 3. After pressing and releasing the clutch pedal, press the accelerator pedal. If intermittent impact noise occurs, it may be due to failure or breakage of the release bearing return spring. For double-plate clutches, if a "clicking" noise is heard when the pedal is fully depressed, it is caused by excessive wear in the fit clearance between the intermediate pressure plate hole and the drive pin.
