What are the causes of clutch shudder?
1 Answers
Clutch shudder can be caused by the following reasons: 1. Uneven distribution of normal pressure between the driving and driven discs: In a friction clutch, uneven spring force of the pressure springs, inconsistent adjustment of the release levers, and/or uneven ends of the diaphragm spring fingers can lead to asynchronous engagement timing, uneven force distribution on the pressure plate, and even tilting of the pressure plate, resulting in poor contact between the driving and driven discs and causing clutch shudder. 2. Weakened damping spring force: A decrease in the spring force of the clutch torsional damping springs, weakened force of the clutch pressure springs, or cracks in the diaphragm spring can all cause shudder during clutch engagement.
