For those of you who are interested in repowering your non-Tyco locos, I found a cheap supply of good motors. These are 5-pole, skew wound, DOUBLE shaft motors. They are 30mm long, 18.5mm wide with 2mm shafts. Cost? Try $5.70 each!! I have some of these powering 6-axle Athearns with no problems.

Hey Pal:
Can you get a shot of one of your installations? And of course what was involved?

I'll see if I can get a photo. The work is actually quite easy. I generally mount the motor to the chassis with clear silicon sealent. I add a flywheel or two to the shafts and then mount the original drive line pieces as long as they fit 2mm shaft.
The motors have a 2mm shaft diameter. This is too small for the original Athearn parts to press fit on, so you can use A-line parts. AHM, IHC, Model Power, Walthers, Atlas and others use parts that press fit just fine on the 2mm shafts.

Hypop, I was wondering if you had found these motors. I bought 8 of them, and they're some of the best I've seen, so I've been telling everyone about them. The low-end torque is amazing. Aside from a smaller bearing on one end, they're the same ones that Rivarossi used in their 90's production locos, and the Allegheny. A friend said this seller is the former owner of Hobbytown, and that these are what they were using in the Hobbytown diesels. They were $5 apiece when I bought them.

Hey Nelson,
Yep, I finally found them! I had picked up a couple awhile back and thought they were great especially since 3 set me back only $25 or so. Now I can get them for a whole lot less!! I bough 5 and plan on buying another 5 or 10 on payday. That should give me plenty of motors for future repowering projects.
The price did go up slightly to "cover the increased ebay costs". I don't know about you, but he could raise the price to $10 and I'd still feel like I'm making out like a bandit! Quality motors under $30 a piece are hard to find these days.

Hey Nelson:
How much smaller is the bearing you mention?
Have got any of these mounted in smaller loco's?

| Romcat, how small of a loco did you have in mind? You could shoe horn it into an Athearn switcher with a bit of grinding on the frame. That motor will fit into an AHM GP18 no problem.

| You should be able to squeeze that motor into those switchers. You may need to grind down some of the frame in order to get the motor shafts and worm shafts into ailignment. I've dropped a similiar motor into an Athearn S12 and just needed to widen the motor area.

Gareth, the bearing on the side of the motor opposite the lugs is somewhat smaller on these to make room for the tapped screw holes. If you were doing a direct replacement, this might be an issue on Rivarossi Big Boys, Alleghenys, etc. where the motor cradle uses the bearing to hold it down on one end, IIRC. It wouldn't be hard to shim it to fit though.
Hypop, I totally agree with you about the price... an extra 70 cents hardly makes a difference with motors this good. The motors Micro Mark sells are normally almost 5 times the cost of these, and I'm not sure they're even as good.
I just checked it against an Athearn SW1500, and I think it would just fit with the fuel tank ground out.

| Nelson, I've used many of those Micro-Mark motors. I even shoe-horned one into that S12 I mentioned, so I know one can fit. The micro-mark motor is about equal to these motors, just much more expensive. Like I said, $10 each would still be a steal. Hence why I plan to pick up a bunch more!
