Lionel Pre War super motor

I used this for my 253.

You could bypass the switch if you just want to see if it runs by connecting one of the brush sires to ti field wire and applying voltage from the frame ground to the other brush wire or pickup. I m also in the process of rebuilding a #8 standard land had the wheels off and the frame apart to install new pick-up/rollers.

Another tip for working on open-frame prewar Lionel motors is to get a big can of CRC Lectramotive spray, and apply liberal amounts directly onto the mechanism, armature etc. Gets all that nasty decades old brush dust, grease and other gunk out before I go servicing one of those motors.

Just a word of caution with the CRC. I Used the contact cleaner doing a prewar motor from a 158 and had the bright idea of applying the stuff with the motor running. The sparks started the stuff on fire when I was spaying. It is funny after the fact and fortunately nothing was destroyed except for my pride

Poppi, are you doing a complete rebuilt (repaint)? Could you post pictures?

not a complete rebuild, just tryin to get the motor running and leave the chassis and body as is. I like the character of the old trains and their small dings and imperfections. I only do a complete paint job if the train is a complete basket case.

the motor runs, im just trying to find where to attached the center pick up. seems like every time I think ive figured it out and try attaching it, it just shorts out. as soon as I remove the wire from the center pick up, the motor runs fine.

ALso as a side note, How in the world do you replace brushes on this little bear!! that is a job in itself.

Not the expert on this just did it once (last week) and my wheels were off and the motor side cover was off.
The brush assembly is held in with a screw, if you remove the screw you should be able to slide it out from the bottom.You may have to push the brushes in while puling the assembly out. Just be careful not to damage the armature.
Once you have it out and decide to replace the wires and brushes, be careful as when you pull the screws off the spring will pop out (could get lost I did not know this but found the spring). Just take your time and do not rush. Also the Motor Doctor has a sight on doing this http://themotordoctor.com/lionel_super_motor.htm
You may want to see if your collector is shorted out. I would use a multi meter for this. The collector wire may be pinched or laying on the axle with the insulation worn off.

Maybe someone would have a better idea on removing the brush assembly and instaling it back in.
