Flywheel/clutch wear-pix

[JTL]

Got the engine out of the car yesterday and today it went on a stand. I proceeded to take off the pressure plate to get to the clutch because was a pile of little bits and shavings present. Sure enough, the clutch disc was down to the rivets. I don't know if the flywheel should come off for resurface or not. Could someone please advise?

For all the trouble you gone through so far, it would drive you nuts if you put all back together without resurfacing the flywheel. It can't cost much. Do it.

IMO, that flywheel is toast. Don't think a resurfacing is possible without exceeding the spec. Definitely pull the flywheel and have it measured to see if it's salvageable; typically when you let the clutch go down to the rivets your buying a flywheel.

I would at least resurface it to see if it is in specs.

Naah, my expirience is far from it. Rivets will do some scratches on surface but typical flywheel can be resurfaced at least twice before it goes below minimum spec. Actually, I never eve saw a flywheel >worn< thin, only overheated and cracked flywheels had to be replaced.

It's resurfacing itself that is the real problem. Surface is often severely hardened and you need expensive CerMet cutting tools in order to penetrate trough it.

...and once the surface hardening is cut-through for the re-surfacing process...it would be "good" to re-establish a "hard" surface again..

plus...not just check if you're still in thickness spec..but if you're completely square on the re-surface. Lots of "checks" to do... I don't trust many guys nowadays and always end up checking more than I had to...

( or go new ! )...

Thanks for all the replies. It sounds like I'll be pulling the flywheel and getting it checked.
Is there any advantage in a 'power' clutch kit vs. original? It seems the clutch disc is different. The following is fs on evilbay for $309+ship:

Seems the rivets are all one one radius. If they haven't dug a deep groove I would have it resurfaced. Mine was some 30 or 40 bucks here in California with its inflated labor and shop rates. So it is well worth a try. Find a good mom and pop machine shop - they'll tell you if it meets specs afterwards.
