one of my lot-o's stopped last night and had one of the bearings out. i think the bearing could be changed. just checking for experience in this task. charlie

Charlie, the lack of replies may be the answer. I don't know what kind of motor it is but if you can take it apart and remove the old bearings you can replace them. Finding replacements may be hard but exact measurements and the internet should make it possible. When you take it apart pay attention to any very thin shims next to the bearings. They are thrust washers and keep the shaft centered. Bearings are either ball or sleeve. You may find replacements through a small tool repair center. The good old motor repair shops likely wouldn't carry anything small enough but may know where you could find them. Good luck.

I've never changed Lot-O bearings but tried to change bearings on other small electric motors before. I've fit and replaced thousands of bearings in my life but I'll be darned if I could find small replacement bearings for small motors on line or anywhere else. They may be out there but finding them is another story. Good luck. connrock

ok, took the plate with the bearing in it off the motor. right away i can see the armature shaft is too small for the bearing connection and it is not a bearing that does not need lubrication. there is a small plastic tube that goes into the bearing for lubrication. i think i can test it by shimming the shaft to be tighter in the bearing which does not turn anyway. there was some time of sawdust or something that held lubrication for the bearing. i will have to find a substitute for that, if not anything else, sawdust... charlie

If the armature shaft end is completely round the bearing likely had a center that wore away. You may be able to find a bronze bushing that fits. Look in the hardware drawers at the local hardware. Drill a hole in the bushing to line up with the oil port tube.
