- Slipping occurs when the driven disc fails to rotate at the same speed as the driving members when the clutch is engaged. This condition occurs when the pressure plate fails to hold the disc tight against the face of the flywheel.
- Normal wear of the clutch lining causes the free travel of the clutch linkage to decrease, creating the need for adjustment.
- Improper clutch adjustment can cause slippage by keeping the release bearing in contact with the pressure plate which can cause the pressure plate to be in a slightly released position.
- Binding linkages prevents pressure plate from exerting full pressure against disc. Inspect release mechanisms for rusted, bent, misaligned, sticking, or damage components. Wiggle release fork to check for free play. Also broken motor mounts can causing binding linkages from excessive engine movement.
- Grease and oil on the disc.
- Driver resting foot on clutch pedal causing bearing to ride on pressure plate and keeping plate in slightly release position.
- The hydraulics of the car could be faulty. Check clutch master cylinder, slave cylinder for any signs of leaking or failure. Hydraulics could have seized and keeping pressure plate in slight release.
- Flywheel improperly resurfaced or incorrect step.
- Vehicle is over powering clutch.
- Damaged or bent clutch assembly
- Improper or damaged release bearing.
- Clutch disc has broken or missing friction material.
- Clutch assembly not fully seating in – improper break in procedure
