What Causes the Abnormal Noise When Pressing and Releasing the Clutch?

[StKylie]

Reasons for abnormal noise when pressing the clutch: 1. Bearing damage: The release bearing is severely worn or lacks lubrication, or the bearing return spring is too soft, broken, or detached. 2. Loose rivets: The driven plate rivets are loose, the steel plate is cracked, or the damping spring is broken. 3. Damaged pressure plate spring: The clutch pressure plate spring is broken or the release bearing is loose. 4. Damaged release lever: The clutch release lever is broken, excessively worn, or the release lever adjustment bolt is broken. Extended content, diagnosis and troubleshooting of clutch abnormal noise: 1. Slightly press the clutch pedal to make the release lever contact the release bearing. If a 'grinding' sound is heard, it indicates abnormal noise from the release bearing. If the noise persists after lubrication, the bearing is excessively worn and should be replaced. 2. If the noise occurs when the pedal is fully pressed and disappears when released, it indicates loose or broken clutch damping springs. 3. If the noise occurs when the clutch just engages or disengages while repeatedly pressing the pedal, it indicates loose rivets or excessive spline wear. 4. If there is intermittent collision noise, it may be due to axial movement of the release bearing, and the release bearing return spring should be replaced.
