All,
its been a while since I posted on this project. Per suggestions from this discussion group, I ordered a new 3-phase motor and VFD Dealers Industrial equipment in NY. I was excited when it came back in Jan but then I broke my arm and have been out of commission for a long spell.
Just working on it again now. I've built an adjustable platform so i could adjust the belt tension for the various step-pulley sizes. (see pix) After testing this I realized that the bearings in the headstock were not in good condition. Seems that these are semi-standard bearings from the ~1953 vintage lathe - ND C88505 and I see them available at a few auto parts stores in the area.
My question is about removal. When I opened the outer dust cap - as you face the lathe with the headstock on the left, this would be the leftmost end, the
entire bearing was rotating in the machined headstock. This of course means that the bearings are shot but is there anything else I need to do when I replace it to stop the entire bearing from spinning again?
Would anyone know the best way to remove the bearings - do I need a puller for this? Also any pointers for reinstallation would be helpful.
If there's a little longitudinal play in the shaft, should I try to add some shims?
thank you
