The drive strap should be an even ‘S’ shape. It is designed to transmit power
from the cover to the pressure plate and subsequently the clutch disc. Distortion
will cause clutch Drag, harsh clutch operation and clutch Judder.
This is normally caused by:
Incorrect bolting sequence used during cover fitment, damage caused during
improper alignment of the disc,or dropping the cover prior to fitment.
If all the drive straps have a similar degree of distortion, the cover may have
suffered a severe shock during operation from poor driver technique.
(e.g. Selecting the wrong gear at speed, towing heavy loads, driving with
severe clutch Judder or with loose engine mountings.
