I've cleaned it up and painted it but was wondering if there is any other preventive maintenance I should do before installing it. Thanks for any suggestions.

I'm not 100% sure on this, but I think those motors run on little bronze bushings. Sometimes there is a small felt pad sandwiched in with the bushing that acts as a mini-dust seal AND a reservoir for lube.
If you could get some oil into these felt pads it might save your motor from the dreaded 43 year old 'howl syndrome'. This would probably require disassembly, so it might be too late for the shiny newly painted motor.

When I was working on my 53 my motor was seized tighter than my wallet (and that's saying something, lol). I did much the same as you, pulling it apart and cleaning it. I'm not sure if yours has sealed bearings, but if it does I drilled a very tiny hole in the rear of the motor and dripped oil into it until the felt pad that Atomarc spoke of absorbed the oil. It was a bit messy, but I knew it was full when the oil started running back out. Then I wiped it clean and put a dab of silicone on the hole to seal it. However, you might not want to drill holes in a nice motor, so it's just a thought. Hope it helps! Good luck. | | |
