I just repowered a RR (rivarossi) Dockside with a CD tray motor, and an Atlas/Kato worm that halves the speed.

The Atlas worms are great, because they mesh perfectly with the axle gear, but are single lead instead of twin lead like the original worms.

Thanks. there was a guy selling a bunch of them on eBay a few years ago, and I bought myself 7 of them for use in Mehano diesels, but never gave it a thought to see if they meshed with any Rivarossi gears until a week ago. He listed them as an Atlas Alco part #707315, but all I can find on Atlas part sheets is 707305.

The Dockside runs so smooth and quiet now that it's like a whole different engine. This is a much better option than putting a NWSL gear set on and having the original motor screaming at top speed. There was a large hole in the motor that I tapped for one of their 2.5 mm mounting screws, but I came close to damaging the windings, and the burrs were really hard to clean out of the motor.

Hi Nelson,
I was looking at the photo you provided in the URL and can't quite figure out what you did. It looks like you installed the Atlas worm on about half way onto the CD tray motor shaft and then somehow you got the CD tray motor up close to the original AHM motor mount. Did you modify or grind off some of the frame area just aft the original motor mount to get the motor tight up against it? I am trying to use this same setup, Atlas gear and CD tray motor (13 volt) and can't seem to get it. I can add an extension bushing onto the motor shaft and then fabricate some kind of brass motor mount, but if I can do it easier, I would be up to that instead. This is for my AHM C-16a. I was going to go ahead and use the original motor and while it seems to run ok, has significant sparking on the left hand brush. The left hand brush is made out of some kind of tightly wound brass/copper screen and I don't want to chance burning up a decoder if a brush gets welded on me. So, since I have a bunch of decent can motors, I will go ahead and remotor. I also have a pretty decent size motor that fits pretty darn good, but it is very visible from the back of the cab, so I would prefer the CD tray motor, so I appreciate any pointers you may have.
Thanks and regards,
