What Are the Causes of Abnormal Noise from the Clutch Spring in a Car?

[McAnderson]

Detailed causes of abnormal noise from the clutch spring in a car are as follows: 1. During self-inspection for abnormal noise from the clutch spring, slightly depress the clutch pedal to bring the release bearing into contact with the release lever. If a 'rustling' sound is heard, it indicates noise from the release bearing. If the noise persists after lubrication, it suggests excessive wear, looseness, or damage to the bearing, which should be replaced. Depressing and releasing the clutch pedal, if intermittent collision sounds occur, indicates axial movement of the release bearing, and the release bearing return spring should be replaced. Repeatedly pressing the pedal, if noise occurs just as the clutch engages or disengages, suggests loose rivets or exposed rivet heads on the driven plate, which should be replaced. 2. Excessive clearance between the spline hole of the driven plate and its spline shaft, annealing, fatigue, or breakage of the driven plate damping spring, loose rivets or exposed rivet heads on the driven plate friction disc, and excessive wear clearance between the drive pins of a double-disc clutch and the intermediate pressure plate and pressure plate pin holes can also cause abnormal spring noise. 3. Lack of lubricant in the release bearing, leading to dry friction or bearing damage, no clearance between the release bearing and the inner end of the release lever, severe oil contamination or dust accumulation between the release bearing sleeve and the guide tube, or fatigue, breakage, or detachment of the release bearing return spring and pedal return spring, resulting in poor return of the release bearing, can also produce abnormal noise.
