What did I break!!!

Dreadnaught

I still don't see how that part of the diaphragm got bent just by you trying to loosen your crank pulley bolt?

With the car in gear and the clutch pedal up, the clutch disc is in contact with the flywheel which spins the input shaft of the trans, the drive shaft then the wheels. The tip of the input shaft sits in the pilot bushing. The input shaft has splines which goes through and aligns with the clutch disc.

The throw out bearing makes contact with the diaphragm. It goes over the input shaft. When you push the clutch in, the CSC pushes on the diaphragm to disengage the clutch disc.

Are we not getting all the deets? Or am I just not thinking enough of how this could have happened?

Yes coincidences happen. I've fixed cars for what it came in for and as the lot attendant goes to take the car to the drive, the check engine light comes on for something else and I'm labeled as a thief.
