Two years ago, I picked up an AHM Indiana Harbor Belt 0-8-0 Switcher Kit in O Gauge from the Great Lakes Train Store in Sterling Heights, Michigan for my train collection at home. Last year, I had started work on it, and when I was about to put the drive wheels on the frame, I noticed I was missing the last four wheels each for the engine frame and one of the truck tenders. Tonight, I sent the Rivarossi Company (that made the kit) an email about the problem and asked them if they had any parts for the kit left. They sent me a reply, saying that this kit was made for the AHM Company in our country. Since this kit is decades old, they only do European trains in this day and age. So, what's next for me? It might work if I transfer most the kit to a Lionel 0-8-0 engine chassis and get some new trucks for the tender.

I dunno; the idea of a Lionel transfer might work, not sure. You'll have to pack a lot of weight in the boiler, that's for sure.

I do know that I built one of those years ago; the valve gear was monstrously difficult to assemble. I later obtained a motorizing kit, but the tiny 3-pole motor was pretty much useless. I think I ended up putting a Pittman motor in it, which helped greatly...FWIW.

This ought to be easy - the drivers were often replaced with metal tired drivers, available with the motorizing kit.

I built one of those un-motorized kits years ago (bought it new from Klein's) and it had metal-tired drivers. I never got the motorizing kit  and could not persuade Ken Henry to build me a drive train for it. We were both members of the WB&A tractioneers at the time so I had frequent contact with him.

Opinion, these AHM IHB's are numerous on E-Bay and can often be had for cheap, I would not kill myself reworking the chassis for this unless you had one of the CLW retrofit drives to replace that factory drek, as the CLW set is a quantum upgrade over the AHM/Rivarossi drive, and puts the model on a level field with at least Weaver's, other CLW 's, AN's etc , and if you have an older 8 wheeled drive like Hines for example, by all means apply.  

The factory HO motor on these is indeed an Achilles heal, but again if you can get a cheap donor for those missing drivers the finished factory-drive model can work with short consists of Delrin trucked cars, preferably styrene 70's era AHM or Roco's. However pulling either old school O Athearn/AN etc or newer Atlas cars of any real length and you'll smoke that HO motor in a few short minutes.

Your "mileage" my vary.  I have one of them with the original drive and I just periodically replace the motor with a cheap donor off of ebay, usually one of those industrial switchers no one wants.

Yow!  Mine cost $12. New.

This is a spectacular plastic model.   I gave mine away.  It ran just like Pete said.  Valve gear worked fine.  Get the Max Gray version - lifetime brass, not as well detailed, worth ten times the plastic one.

Opinion.

"Yow" is right!   

In my humble (and no doubt useless) opinion, that is way too much to spend on something you'll probably end up modifying anyway. If you think you might someday lean towards going 2 rail, I think bob2's suggestion of looking for a Max Gray is the wisest approach...or just find an already built AHM model.

If you want to stick with 3 rail, it seems there are often very affordable examples of the MTH "Rail King" 2-8-0 on eBay. Perhaps you could make one of those fit the AHM superstructure...Happy hunting!

Andrew, take bob2's offer and get the wheels (and axles?).  The rear tender truck takes regular AHM wheels with the thin axle ends, might be some 3-rail alternatives in your spares box that could be filed down to fit.  The front tender truck wheels have square(??) axle ends to fit the outside cranks.  If they are the ones that are missing, just find a different O-scale truck, no-one'll notice, lets keep this cheap for the moment. 

Yes, get a circuit of 2-rail track, but first do the loco, it'll fit on your 3-rail track and as an 0-8-0 might get round some of the curves - pushed by one of your other locos?  This is all about fun!  Finding good second-hand parts, buying brass, creating a layout that looks more like the real thing is just waiting for you.  Us Brits realised that 2-rail O-scale is it many years ago and luckily Lionel never signed up all the retailers over here.

Keep us up-to-date with your 0-8-0 and BTW several O-scalers over here have found a front (Pony) truck and made a 2-8-0 road engine with plain tender trucks, look good.

I think he fainted at free. Give him some time to recover 

(too cool Bob 😎)

I have the 382. Its small wheel  flanges dont like tube track much, nor tight curves. I run it on 0-36 Super-O reliably (after a pilot truck mount mod) , semi-reliably on 0-32 tube track. I'm betting the 382 (4-6-0) is more nimble than yours fyi. But it also exceeded my expectations with great low speeds and pulls as well as a L-General, maybe better. 

I'd still finish, but you may need flat top rails to be really happy.

Conversion from 2r to 3r was easy. Tie all the wheel contact plungers together as one polarity, and add a roller set to the gear cover, tender, etc. for the center rail. Use a bridge rectifier to get DC from AC track.(no reverse, but a reverse board is another option. A BR is just dirt cheap; like me .

Hi all, picked up a 0-8-0 AHM/Rivarossi U-4A, it has rollers and a E-unit I did not take the shell off yet, it does run a little slow forward and fine in reverse,, does anybody have this engine in 3 rail? Anyone have a parts list? And how is the best way to get missing parts. Any help will be great. Engine will get a good service and I will find out what type motor. Thanks

Wow.  Lots of rust and corrosion Mark.

Even getting all the metal to metal surfaces cleaned up would certainly help.       After you get her opened up and all the lubing done let us know how it runs.   Maybe a video.  Good luck.

Thanks Dallas, right it will get a good service after I take the shell off and see what we got. Fun project. God Speed, Mark

Wow!  I would love to know what motor, parts, wheels, etc., were used for this interesting conversion!!  Since the original was made for 2-rail operation, at least half the wheels were plastic.  Where did those wheels come from, and how is the motor connected to them!?

Ted, Finally took the shell off here are some photos. The past owner put in a PW Lionel motor along with a E-unit, Motor is getting degreased. Lot of plastic parts to bad the frame wasn't diecast, Will send a video when up and running. God Speed!

Hmm... looks like a Lionel 736 Berkshire gave its life for the cause.  What's interesting is that the builder wisely chose to put the worm wheel on the THIRD driving axle (which minimizes the amount of accumulated "slop" in the side rods, transferring movement to the other axles.)  Probably for ease of packaging, Lionel and American Flyer designs were often geared to the LAST axle, a sacrifice of performance which unfortuntately has persisted to this day.

Are the wheels metal?  And is that a magnet I see above the last pair of drivers??  Sorry for all the questions, and thank you for taking the time to share details of your unique find!

Yes Ted all wheels are metal and that is metal stock, don't know if the past owner put it in or was with the kit. See how she runs in a few days. maybe a member has one that has been modified and will share some history about this engine. God Speed! Mark
