The stethoscope sounds like a good trick. I'll have to try that out!
I made some more progress on the ol Kondia last night. I think Ive spent more time building tools than actually working on the machine. Id be nearly $150 into spanner wrenches by now if I went out and bought what I needed. But with a lathe, a welder and drill press, Ive managed to get the job done with some scraps of steel and some time.
The most elaborate was this one for pulling the back-gear. I was afraid to just throw a puller on there because it would only engage on 2 teeth, so I cut this ring and welded a few off-set tabs so it can come apart and still be flush on top. It worked like a charm.

At this point I have the upper bearing assembly all the way apart and the back-gear assembly apart.

New bearings are in-hand. I could only find ZZ bearings, but the upper assembly calls for a single shield and the back-gear bearings are full open. So I just de-Zd them as necessary. J

I also got the VFD re-mounted on the front side of the machine. The previous owner had it mounted on the back of the machine for some inexplicable reason. Since I have to use the VFD for starts and stops, it kinda needs to be readily accessible.
