It is also important that the wear surface is above the center of the
flywheel. I have seen the disc center springs worn out from rubbing on the
flywheel center. VW used to sell these rebuilt. The rebuild was metal
sprayed to build up the friction surface and they were ground, not cut on a
lathe.

The hard and fast number for all 228 MM flywheels is .970ths I have a dept
gauge with a digital read out that sits next to my flywheel grinder for this
purpose A vernier caliper can also be used to measure dept

Its common to see flywheels that are out of spec from prevoius incounters
with a mad machinest suprpising most worked without complant

Hope that helps.  Found via google search string:  ["flywheel specs" site:
gerry.vanagon.com].  You might want to repeat this search and see some other
emails on the subject.
