What Causes Vibration When Pressing the Clutch Pedal?

[DeDominic]

Here are the specific reasons for vibration when pressing the clutch pedal: 1. Uneven distribution of positive pressure between the driving and driven discs: In a frequently engaged clutch, uneven spring tension of the pressure plate springs, inconsistent adjustment of the release levers, and/or uneven ends of the diaphragm spring fingers can lead to asynchronous pressure application, uneven force distribution on the pressure plate, or even tilting of the pressure plate. This results in poor contact between the driving and driven discs, causing clutch vibration. In this case, the clutch pressure springs should be replaced, and the release levers should be leveled. 2. Weakened damping spring tension: Weakened tension in the clutch torsional damping springs, weakened clutch pressure plate springs, or cracks in the diaphragm spring can all cause clutch shudder during engagement. The solution here is to replace the affected springs. 3. Poor contact of the clutch lining: Poor contact of the clutch lining, surface hardening, or adhesion of sticky substances can easily lead to clutch vibration. In such cases, the clutch lining should be re-bonded.
