Fixing Up Century 1/3 HP Single-phase Motor

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am hoping to fix up this old Century 1/3 HP motor that came on my Clipper 2B seed cleaner instead of buying a new motor. I'd like to be able to use it to clean some wheat soon and plan on using it for other crops as I start growing more. The motor seems old enough that if not original to the cleaner, it can't be too much newer.
The motor and seed cleaner shafts were locked up when I bought it over a year ago. I freed up the cleaner by hand yesterday, and put a chain wrench on the motor pulley. It broke free with very little effort. I pulled the cast iron pulley off last night and it fought the whole way, and got slightly bent, so if I can't straighten it I may be replacing it. It obviously needs a new cord.

What's the best way to confirm the motor is still good, and put it back into working condition? I was planning on cleaning all the dust/mud dauber nests out and changing bushings/bearings. I'll do what I can with a multimeter to check the windings. There doesn't seem to be much play in the bushings/bearings; however, there is some end play in the shaft. Anything else I need to know about? I do not work on electric motors much.
