Maybe for a lionel fan motor, but folks have been oiling MTH motors forever. Many case you can access the bearing with no disassembly at the gap between housing and motor. Frankly, it is just part of the service I do if I have an engine open for some other reason. Another folk lure like batteries killing 5V boards. No proof of that and in the last month I service 5 PS-2 5V engine that worked with original white batteries. Still ran. I standby oiling if it is just a whine. G
