Reply to "Throw out bearing"

On another front, A Pantera owner recently installed a new steel flywheel from Jegs on his engine, and the clutch locked up disengaged during his initial 2-mile drive! After lots of e-mails back & forth, he determined the 'far-east-made' flywheel was thinner at the crank flange than stock. That let the throwout bearing over-travel on the ZF nose-piece, so the front end of the bearing cocked and caught on the front of the ZF nose-piece. After a short tow-truck ride home, he had to repull the ZF to release it. There are a number of fixes for this but his last words to me on the subject were "SUPPORT YOUR VENDORS"!!
He reinstalled his old flywheel. Note also that aluminum flywheels may have thicker, or thinner crank mounting flanges than stock, but either can be a source of frustration until you sort it all out.
