Speaking of motors...
My current update is one of both good and bad news. The good news I got my DP all put back together, motor mounted, and running. Everything looks and sounds like it's running as smooth as glass. I don't have a dial indicator, but to the naked eye, runout doesn't look bad. As a side note, a little trick I picked up either here on GJ or somewhere was to use an Irwin Quick Clamp with the jaws reversed to adjust belt tension. Put one end on the motor housing and the other behind the head frame behind the badge and gradually tighten belt. Worked great.
Anyway, now for the bad...after running about two minutes I started smelling a burning smell. Shut it down and a small stream of smoke comes out of the pulley end of the motor. It's not what I would declare a typical burning wire smell, so I'm thinking maybe some paint is burning off from my repaint job, or possibly the belt is too tight and the bearings (which I didn't replace) are doing something funny. I loosened the belt a bit, turn it back on, and sure enough about a minute or two later it starts doing the same thing. Great...

At least at this point, the motor is still running for all that's worth.
So I take the motor back off, and decide I'm going to have to crack it open again. I don't see any evidence of burning or scorching anywhere on the housings, on the condenser, stator, centrifugal switch, or anywhere else. As I roll the motor around I finally see some of the windings are now black, whereas they hadn't been before (see attached photo).
Even though I tried to be super careful when I revamped the motor I'm suspecting some of the varnish insulation fell off the windings and this is causing my issue.
Does anyone have any thoughts about what's going on here and what the solution might be? I'm not an electrical guy by any remote stretch of the imagination. I did find a product someone somewhere recommended called Sprayon Insulating Varnish which appears to me "may" or was designed to recoat the wiring in cases such as this, but I don't know enough about it.
I'd just as soon not have to take it to a motor repair shop because I suspect they're just going to tell me it needs to be rewired, and quite frankly, I further suspect that will cost far more than what a new or used motor would cost me.
