[DML] Re: Clutch woes

["content22207" <brobertson@xxxxxxxxxxxx>]

In the pic it looks like the remaining piece is bent into the fork's
ball recess. Apologies. 

You need the retainer to hold the cluch fork in place until the
transmission is seated against the engine. Once bolted up, it does
indeed become redundant.

Volvo factory literature doesn't list a torque spec for the allen head
pressure plate bolts. As long as they pull it all the way to the
flywheel, and are tight enough not to come loose thereafter (remember:
the pressure plate spins at engine RPM's -- even 6,000), anything
should be OK.
