lionel super motor repair

Classic Toy Trains Forum

Hi,

I hope that this topic hasn’t been covered ad naseum, but forgive me, I’m new.

I’m trying to replace both commuters (windings, what ever they’re called) in the Super Motors from a 402. I have the wheels off and the motor apart, but I need to get the small gear off of the currently blown commuter before I can get it out. My question is, is this a pry job or are there threads?

If it is a pry job, any tips on how - without breaking it?

Also, where should I lubricate the engine after this repair is complete?

Thanks!

sg_fan,

Welcome to the CTT forum!

I do not have any standard gauge so I am not much help. However, any of my O pre-war and post war all have gears that are pressed onto the shafts.

You will need some sort of gear puller. Some hobby shops that specialize in RC cars carry gear pullers for small motors. There are also some train repair parts vendors in Classic Toy Trains that carry the various specialty tools needed for Lionel repair.

Obviously pulling a gear also means you will eventually need to press it back on.

This can be done with a small press or if you have a large enough bench vice - the vice can be used to smoothly press the gear back on.

Hammering/tapping it on is not recommended (risk of deforming the shaft which on an armature can be non-repairable).

Roy,

Thanks, that’s great advice.

Thanks too for the links, I already have the armature
(thanks for reminding me of the name of the part too)
that I got from georgetebolt .

Does anyone know if the repair CD that Olsen Toys
sells is worth the $95 to someone that only has Standard
Gauge?

If you’ve never used a gear or wheel puller, you need to know that hammering is actually a good idea, but on the puller, not on the shaft. You should tighten the puller but not enough to break it or the gear, then tap on the end of the puller handle with a hammer. You can tell that it’s working when the puller loosens enough to accept some more tightening after you tap on it.
