Gentlemen
I am cleaning up a recently acquired 1969 10EE 30" lathe. This lathe is equipped with a Baldor 5HP VFD drive (no back gear). This was originally a 480v machine and I have been testing it on single phase 480 temporarily until I can equip it with the proper VFD. I have a Fuji ACE VFD which can drive this motor from 240 single phase and am looking forward to getting this set up and operating and expect it will be a good setup.
Unfortunately, I made an unwanted discovery. I notice that when operating the spindle at low RPM (under 100) the pulley -side of the spindle bearing is making a bad sound approximately once every 5 revolutions. Something to do with the bearing race I am sure but that's as much as I know. I can't attach a video unfortunately. I removed the flat belt and am only turning the spindle.
The spindle sounds 'normal' at higher speed, although my expectation was it would be more quiet than it actually is.
I have checked the oil level (single sightglass) and the operation of the tach gear scraper and little mini-reservoir at the top an that appears to be OK.
So I think the only course is to remove the spindle and take a look.
1. Can someone with decent skills perform the disassembly / reassembly? (i.e. me)
2. Are special tools required?
3. Is sanity required?
Thanks
