Since so many have been asking recently where to get parts, I’ll toss in my request. I am trying to repair an AHM E-8 for one of the guys in my club. It is missing the large gear in one of the trucks. The gear is driven by the worm gear and connects to everything else! It is red, about the diameter of a dime, and has 28 teeth. Somehow, it was misplaced, probably before the present owner bought it. I’m not sure how old this engine is, but I would bet 30+.
The next train show in the Houston area where I might find an old AHM engine to strip of parts isn’t until November. The hobby shops and local parts suppliers are no help. Anyone have what I need to fix this? Thanks for any help and positive suggestions. It is missing only the one gear.
You may want to look for newer E8 parts instead. The old AHM/Rivarossi E8s only had metal gears. Rivarossi started making things with the red plastic gears in the mid 90’s. Does the E8 you’re talking about have small flanges on the wheels?
Yes it does. I actually have one axle gear that is split, too. The owner did not know how old it is, and maybe it is from the 1990s. The motor looks like a D-cell battery with two pins sticking out one end that the wiring is clipped to. The flywheel is betweeen the motor and the rear of the engine and is supported between two bushings.
So it is not as old as I had first believed! Now, where to find parts???
I don’t know if you can find parts for the new E8s anymore. Rivarossi went bankrupt last year and was purchased by Hornby, who will probably only do the Rivarossi steam engines. So you might have to look around in eBay for a while or buy a new one for parts.
The new E8s have a flywheel? What does the chassis look like on yours? Mine has a vertically mounted motor directly over the truck.
I added a little weight to mine.[:)]
Your E-8’s interior resembles my Rivarossi KM Diesel Hydraulic, not the engine I am trying to fix. This engine has the motor installed horizontally, not vertically as yours is. There are shafts to both the front and rear trucks. The flywheel assembly is mounted behind the motor, recessed into the frame. I have never seen an engine built like this before, so I don’t know for sure that it is AHM. That is what I was told. The trucks look similar, but not identical, to Rivarossi trucks. I figure I’ll have to find a junker and salvage the necessary parts. That’s OK. Used parts work fine, if they are the right ones.
Sounds to me like you have a Roco/Model Power E7. So you’ll have to find Roco parts for it, not Rivarossi. If the engine is an E8 then it could be that the owner put a Rivarossi shell on the Roco made mechanism.
I looked through my spare parts box , unfortunatly the AHM gears I have only have 13 teeth, the axles also have 13 teeth. These came from the F7 trucks.
I’m pretty sure the boys are right- what you have is a Roco -sold by Model Power and Concor. If that is what it is NWSL should have axle sets for it but you probably will have to change all the wheels. Are there any marks on the bottom of the truck where something was ground off? If so it is from Concor. They may still have parts for the gear train. I have seen these for sale on ebay so you may be able to find a parts basket case there.
No identifying marks on it at all. That’s why I’m having trouble finding parts - I don’t know for sure what to look for. I called Golf Manor Hobbies, but too early. They are open late in the day, and I couldn’t wait. I’ll get them later.
IWhat you have is not AHM (Rivarossi). It is either the Roco model imported by Model Power, or the ConCor model. ConCor got the tooling from Roco, and the parts are interchangeable.
NWSL has axle assemblies to fit.
ConCor may have parts.
These are locomotives are great puller, due to wieght and 12 wheel drive. The AHM/Rivarossi models have only four wheels driven and are comparitively. The models are not very quiet, the problem being the cast flywheel has a great deal of imbalance. You can either balance it, even static will help, or replace with a turned brass one.
nfmisso: Please stop posting that Concor got tooling from Roco as that is simply not true. We bought loose parts from Roco and assembled in Arizona and Mexico. I was plant manager for Concor at the time so I know of which I speak.
I have gotten the engine to run a lot quieter by lubricating it after a good cleaning. It is still a little noisy, but much improved over when I got it. The owner is waiting for the club to go to DCC before getting a decoder, so I have not finished wiring it, though the clips for the motor contacts make that a breeze. This is a fairly well designed engine, in my opinion. There are a few things that probably could have been done a little better, so that it held up longer (the plastic sides of the trucks, for one thing), but overall I think it should pull like crazy once all the wheels are engaged. I still have to find that large gear. I may not worry about the one axle with the split gear. If it does not cause the engine to hiccup, I’ll just leave it alone. You guys have been a big help. I’m convinced the engine is a Roco. I’ll try Golf Manor Hobbies again later today.
