If it's out of spec, replace it, no way I would ever try to bend it back, you could damage bearings and a whole lot more trying to safe a few bucks

That dial indicator resolution was in tenths of thousandths so...it showed only about .001 runout?

Bajaman,

Nope. The larger graduations are .001". The small graduations between them are .0001". That shaft was showing almost .009" runout at that point on the shaft. Should be considered scrap by nearly anybody's definition.

Thanks. Brad.
