ERIC:
The only data I could find came from an old Clymer Publication. I'll
quote as written in the manual: "the maximum run-out permissible on the
disc is .004". Under no circumstances should more than .060" be removed,
with the finish to be 32 micro ins. maximum measured circumferentially
and 50 micro ins. measured radially."
That's all I could find. Good luck!
