What are the causes of clutch shudder?

[LeEmilia]

Here are the reasons for clutch shudder: 1. Clutch shudder: Let the engine idle, engage a low gear, slowly release the clutch pedal and increase the throttle to start. If the vehicle body shakes at this time, it indicates clutch shudder. 2. Uneven distribution of positive pressure between the driving and driven discs: The uneven elasticity of the pressure springs in a frequently engaged clutch, inconsistent adjustment of the release levers, and/or uneven ends of the diaphragm spring fingers can lead to asynchronous pressure application, uneven force on the pressure plate, or even tilting of the pressure plate, resulting in poor contact between the driving and driven discs and causing clutch shudder. According to auto parts experts, the solution is to replace the clutch pressure springs and level the release levers. 3. Weakened damping spring elasticity: Weakened elasticity of the clutch torsional damping springs, weakened clutch pressure springs, or cracks in the diaphragm spring can all cause shudder when the clutch is engaged. The recommended solution is to replace the springs. 4. Poor contact of the clutch lining: Poor contact of the clutch lining, surface hardening, or adhesion of sticky substances can easily cause clutch shudder. In this case, the clutch lining should be re-bonded.
