Clutch grinding on flywheel bolts


Recommended Posts

While the engine is out I decided to change the clutch. I took the old one off and noticed the bolts on the flywheel have been ground down due to contact with the clutch.

Am I correct to assume the flywheel has been machined too much in the past so there is not enough clearance between flywheel and clutch?

 

Picture below if after I removed flywheel but you can see the bolts have grind marks on each one. Its hard to tell but it must have ground at least 1mm of parts of the bolts.

I thought that too but noticed just this morning that the flywheel itself has grind marks where the springs have contacted, not just the bolts.

I'm struggling to find another flywheel too...
