I just picked up a Marx black litho 897 steam locomotive in a lot with several other pieces I wanted. The prewar single reduction motor has a few things that need some attention.
It is missing one pick up shoe for a prewar type motor
One wheel is starting to crack and chip
It needs a new light bulb
It needs to be lubricated (the motor works but struggles)
Is it possible to replace the wheels (it is not a geared drive wheel)? Is it worth it or is it better to just get a replacement motor?
Also, what kind of lubricant should I use on the gears and axles?
Thanks.
