The problem of slipping clutches is very wide-ranging. For example, the clutch of a vehicle may slip only at high speeds. Other drivers complain that their clutch slips when the engine is cold, during starting, when setting off, or in first speed position. Another notices the clutch slipping through much of the period of acceleration, and yet another says his clutch slips after chip tuning. Clutch slipping symptoms and causes are just as varied as the symptoms. Even a brand new clutch can be slipping for a variety of reasons. Besides the clutch pressure plate and the clutch disk, clutch slipping causes can often be found in the release system. Additional causes include an incorrectly reworked flywheel or installation of the wrong clutch.
Check in case of clutch slipping:
- Release system wear, freedom of movement, adjustment?
- Correct parts for the vehicle?
- Flywheel correctly reworked?
- Contamination of the friction surfaces with lubricant?
- Deformation and warping of the friction surfaces on the flywheel and pressure plate?
