Also have to watch the bearing pockets in aluminum housings. If the bearing has been bad any length of time it may have spun and wallered out the pocket to the point where there are several thousandths of slop. New bearings won't help in that case.
I've found that the bearings are a very light press fit on most new motors. No downside for the manufacturer - quicker and easier assembly, and it also wears out in ~5 years. If one used a heavier pocket wall and a moderately heavy press spec on sizing the pocket, the motor would last much longer.
