Red face Motor does not spin smoothly

I just rebuilt my Monster Stock motor (cleaned it out), and after I put on the endbell, the arm doesn't seem to spin smoothly anymore. But when I take off the endbell, it spins normally. I put the Monster endbell on my P2K Pro and the arm spinned smoothly. I can't figure out what's wrong

Do you have too many shims on the arm?

I think I might. It doesn't have any slop. I didn't add any shims though.

The motor has not been over heated.

I found out it's not the shims either. It may be the bushings or something. Because I took out both shims and felt if there was any play. There was none whatsoever. Then I tried to push the arm up and down to check the play again. When I pushed hard, it moved. Could it be the endbell bushing?

Without the endbell on, I pulled the arm up and down. It went freely. So bottom bushing/magnets should be alright.

Default too tight

if you just rebuilt the motor chances are that the end bell ring is bent . try to flatten it out and make sure every thing is lined up .. and make sure the bushings/ bearings are lined up ..

Thanks for the help guys.

Found out it was the can bushing. I swapped my P2K and Monster Stock bushings and it was the problem. Now I gotta polish the original P2K bushing.

Any tips on polishing bushings? How to guide?

Thanx

Polishing bushings - I cut a Q tip in half(add polish to the Q tip), stick one end through the bushing and then chuck into a drill, keep pressure on the Q tip till it passes through the bushing. I usually keep the bushing in the motor. Usually takes alot of Q tips to get it done, but it works.
