I have never owned one of these machines but I have had friends who did. I think they nice machines and worthy of some effort to get running again.
I'll throw out my thoughts on the motor. First off here is a link to Chris Cuff cleaning a motor from an RCA motor from a little 45 changer. http://www.youtube.com/watch?v=tpDpJ3kP318
This motor has some similarities to your motor. In particular the self aligning bearings. Note the procedure he uses to align the bearings as he assembles the motor. As he tightens the through bolts he taps on the motor with a screwdriver handle. He likes lighter fluid for a cleaner. I use lacquer thinner. Both are fine but they are toxic and flammable. Do this outside and please be careful. I would soak out all the old lube from the bearings and clean the motor shafts well. I would not submerge the stator and coils unless you have reason to believe that the coils have been contaminated by some ionic stuff like salty water. If you think there may have been salty water in the coils submerge it into several changes of distilled water. If you have to do that it should go into an oven at ~135 degrees F for several hours to dry out.
Keep track of all of the thrust washers and re-assemble as they were. Criss shows putting a bit of oil on the motor shafts. That is good but I would look for wicks around the bearings at each end. After drying out the cleaning solvent soak the wicks with oil. I like sewing machine oil for this. After you get all the oil into the wicks which they will hold wipe off the end pieces with a paper towel before assembly. You don't want oil on the belt.
After re-assembly of the motor it should spin freely. Did you check this before you disassembled the motor? If the motor still wont run there could be a short in the motor coils. Smell the coils. If there is a short they will get hot and smell real bad.
Let us know what happens after the motor is back together so we can think of the next step.

I completely disassembled it last night. There is a tiny screw holding together the motor pulley. Will I need to remove this screw to clean the inside of the motor pulley. I've only cleaned potentiometers in the past in electronics, never a motor. So is there anything I should know that could potentially damage the motor? Is isopropyl alcohol generally safe to use with motors, as in is it ok to soak the motor in it?
