Nope I kept same tolerance and bearing dimension and numbers. Broke in accordingly and adjusted after X hours.I'm sort of leaning back to maybe bad bearing again. They seem to be running warmer than I think they should be, and used to maybe.
Did you do any upgrade of bearings when you replaced yours?
Spindle beerings should be 40F above ambient temp after 30 minutes or so at highest rpm. For tapered roller any way.
( none splash lube )
Any way you cut it those bearings max temp is 170F
If you are adventurous... rip your spindle out after you take end float numbers. Clean and repack / or just clean and reinstall if splash lubricant. And adjust preload and see what happens.
Spindle bearing tinkering would be my last resort. IMO
