Input shaft, cleaning

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

Checking the function of the clutch

Test drive the car.

If 1st or reverse gear is stiff, but the other gears operate normally or are less stiff, the clutch is slipping. This is caused by excessive friction between the input shaft and the clutch hub.

NOTE:

Moderate tightening of the clutch plates may mean that greater force is required to engage gears, in particular 1st and reverse gears.

Check the center of the clutch driven plate (splines)

Visually check the center of the clutch driven plate. Check that there is no rust or damage on the splines.
