I actually had one of those motors with the four screws in the corners. I 
removed them and proceeded to remove the end caps. I was able to slide them 
part way down the axle of the motor, but after a while, they would slide any 
farther. No amount of hammering with a mallet could budge them either.  
eventually, with all of stress I was putting on the thing, pieces of the 
windings began to fall out. I might have to try this again with a newer 
motor. There was a considerable amount of oxidation on the parts of the 
motor, and seems possible that it could have caused enough friction between 
the parts to keep them from separating well. I'll keep working at it and see 
what I can figure out.
