I have a 9x54 south bend lathe that i restored. it was sitting in storage since the 1950's. good overall shape. When i was getting the lathe restored and up and running I noticed the rear bearing was tight and was dragging the spindle turning by hand. I added .002 shim to it and it was running cool and did not have any problems.
So my spliced serpentine belt broke this weekend so I took it apart to install a solid belt, Lubed everything up and reinstalled everything and the rear bearing is now dragging again, So i put the dial indicator on it and added shims until i had .001 clearance(took .002 more). Now the spindle turns easy by hand but when running at 750 rpms it's getting hot quick. Humm. Im going to take it apart tonight and see what is going on.
Any tips or suggestions. I'm going to replace the felts and reshim for .0015 tonight and see what it does.
For oil I am using Motul 10w fork oil. It’s a full synthetic hydraulic oil used in motorcycle forks its has anti wear and anti foam additves but it’s a hydraulic oil, Motul Factory Line Synthetic Fork Oil - Street Bike - Motorcycle Superstore
