Andre: Make sure the wheels aren't binding on the truck sides. I had this problem with a couple of AM locomotives after I installed Delrin sideframes on them. The wheels treads rubbed the brake shoes, or the sideframes would bind against the outer wheel surfaces. In both cases, I was able to fix the problem with a #4 washer spacer between the truck sides and the gear case cover.
Turn the offending locomotives over, as when you sex a kitten, and make sure the wheelsets have at least a touch of back and forth side play, then make sure the brake shoes are not rubbing the wheel treads.
