GE Lathe Motor Disassembly, with no doubt wiring questions later

[markba633csi]

Does your manual have electrical diagrams? I guess there's no motor reversing switch on this lathe?
The pump should be ok. It will run a bit faster on our 60 cycle power

@Ulma Doctor I'm having trouble with the 1RS bearing. Amazon shows it to be a tapered bearing. I found another with the prefix 205F. It has a seal on one side and it's open on the other like the ones I removed from my motor. Amazon showed a 6205-2RSC3.

My lathe has a reverse switch. Colchester commonly sold this lathe with a 3-phase motor. 220 1-phase was optional and more expensive. They also offered a 2-speed motor. Your post reminded me that I purchased a quality reprint of the manual. Here are the wiring diagrams. I believe I have a single-speed motor, but I'm not sure. I posted the ID plate in my first post. Would a 2-speed motor list two RPM's? I don't know how to tell.

Yes the GE motor you have is single speed. I don't see the starting cap though-
Before you re-mount the motor we should go over the windings with your meter and label them while it's on the bench

The 6205-1RS bearings are better than the 6205-Zbearings, the 1RS versions neoprene seal seals out moisture as well as dust. The Z shield is only good for sealing out dust.
SKF or Timken are good brands

Which ever bearing that you choose will outlive you, it does not matter much

The starting and run caps are held in the underside of the case with spring clips. I haven’t tried to remove them yet.

You can pick one of the seals out when you get the bearing if you get the 6205-2RS

Would there be an issue running them as they come? I see the reason for one open face, to re-grease. Are the ones with two seals intended to be maintenance-free? Perhaps heat build-up?

You can certainly run them as they come.
They are considered lifetime lubricated.
Too much grease is not ideal for longevity.
