[mark '87 930]

Bo,

I just reassembled my engine/transmission and mated them in the last few weeks. I have an '87 and DO NOT have any retaining system. The throwout bearing 'sits' in place and can fall out, however, when mating the transmission to it, the actuating lever somewhat holds it in place (with the ears on the throwout bearing).

If you're in that stage, I'd recommend regreasing the bearing. Mine was dry and made some serious whining noises...
