Hello everyone, I recently put a new pressure plate and disk in my 70 w/out surfacing the flywheel. Once completed, whenever I would reach the release point it would not only chatter but make a terrible raspy sound. I know you're all thinking the disk must've been installed backwards; however, I just pulled it all back apart and it wasn't. The springs on the disk were riding on the bolt heads of the flywheel even though it was installed correctly. I took the entire kit + flywheel back to Napa for examination, and the recommendation was to order a new flywheel and re-check the tolerances. I guess my real question is if the flywheel is this far out of spec, why didn't it make noise with my old worn out disk? FYI engine is a 455, M21, w/ Hays flywheel resurfaced once 10 years ago. The Napa rep believed the flywheel bolts to be correct, very shallow, they look almost like studs w/ a nut screwed half way on
Just realized I probably should have posted this in the tech section, can a moderator please move if necessary.
Thanks in advance
