I've cleaned up my stock '77 flywheel and was wondering how smoothe the friction side should be. The book I have says use "fine sandpaper" that could be 120 grit or 1000 grit. Should it feel like glass or paper? I have a new Exedy #6009 clutch kit. Thanks for any replys.

Take it and have it turned on a lathe. Even if you only have .002 taken off it will be perfectly FLAT then. About $15. Be sure and use brake cleaner to remove the cutting oil used. The shops leave it on because customers don't like picking up a rusty flywheel, which it will do in a matter of HOURS if it isn't oiled.

As for light sanding....sure, some 200 grit, or a roto zip wheel, and afterwards wash with SOAP AND HOT WATER to remove the grit left behind.

I've found, if you're not having clutch problems, none of this makes any difference anyway, and if you ARE having clutch problems....it STILL doesn't make any difference. . Clutch judder problem? See other threads.

Comet and Ajax are great cleaners, abrasives and degreasers in one.
