In Reply to: 1958 W100 advice re clutch disc, pplate & flywheel condi posted by RWR on Saturday, May 06, 2006 at 11:49PM :
Unless your flywheel is worn with grooves which requires resurfacing by a machine shop, using sand paper is the proper method to remove the glaze off the flywheel and disk cover. This is something you do want to do, if replacing a disk, or in this case, just cleaning it. Afterwards, you wash the flywheel with a good soapy mixture of dish soap and water to remove the grit. Solvent will not remove hone or sand grit. If the clutch disk has minimum of 1/32 from material surface to the rivets heads, I would replace it.
In fact, since doing all this work, I would look at buying a new cover/disk kit and pilot bushing and throw-out bearing. Just saves having to do this again in the near future.
