I have just finished installing new spindle bearings in my Nardini 12” lathe. Bearings are Timken tapered rollers, front and back. After running the machine for a couple of hours, I measure about .0003 inches end play. The spindle turns free and smooth. The manual is silent about bearing preload or end play.
So my question is should I tighten the bearing some more and run the risk of overtightening. Or just leave it as is?
