While testing more 50 baud Telex boards at work today, I did some overhauling on this little metal 0-4-0 Camelback, I believe it's made by New One in Japan. Anyway, another dusty storage project I pulled out to work on. So, I disassembled the motor, the brushes were tight in the slide tubes, there was so much gunk. I finally got them out, and cleaned out the slide tube and the brushes. Some burnishing of the armature pads, and cleaned out the grease box and cover, and then about ready to reassemble.
   
The axle pass-throughes needed some reaming, and one pass-through had a flat spot on both sides, so I filed that some, too. I got the entire chassis cleaned out, but didn't have any grease to put in, so I left it disassembled, and bought some grease at my hobby shop job afterwards, and will complete the rebuild on Wednesday. But the motor runs really good now, before it would barely turn over, it had so much gunk in it. I think the steam chest rods are binding, too, so I took them off. When I did run it down the track briefly, before I cleaned all the grease out, it was jumping a bit,even after steam chest rods were removed. So I'm hoping some new grease and filing that flat spot down will help it run more smoothly. May have to ream out the steam chest holes some, too. At any rate, Engine #2 this week is making progress towards re-animation. Still haven't run the Cox Army diesel yet, will try to do so tonight. But I figured, since my real job is slow, I may as well start taking some projects to work, and fix them there, where I have more room, extra tools, and can sneak some time in on them while testing circuit boards. Plus having the professional soldering iron there is handy, too.  Maybe I will get some stuff done this year, as I don't seem to have much energy when I get home these days.  So another open-frame motor is about ready to do business again.

I picked up one of these for about $10 at a train show. New One made some intriguing locos, but they were cheaply produced and suffered from a lot of problems. I got the motor running well enough, but it vibrated at higher speeds, so I took a crack at balancing the armature.
That helped some, but since they soldered in the bearings -- ruining their ability to hold oil -- they were too worn for the motor to ever quiet down. The brushes were also some weird composite that left trailing burrs behind them as they wore on the commutator. Finding a junker at a later show supplied me with a replacement motor, which has press fit bearings and runs much better. I also replaced the brushes and found some springs that aren't as stiff as the originals.
Good luck getting yours back on the rails.

Mine seems to run good right now. I got a new one/silvine that has a square style Rivarossi motor in it. Big difference!

I did hear those New Ones don't have a very good reputation in terms of performance and overall quality. I've even heard about how their locos have zamac, which is known to corrode over time and ruin the locomotive.They are cool looking locos though.

I do have a 2-4-2 from the same importer. A lot better due to it having a standard style power train set up with a open-frame motor. I do see the tender trucks tend to fall apart easily.

| Zamac isn't the problem, it's the quality of the zamac. It would vary from batch to batch. If you got an engine made from a good batch of zamac, it'll last forever. Bad batch of zamac, zinc rot/pest.

Considering that these engines are already 40+ years old at least, and I don't see any cracks in the ones I have, I'd have to say that they should be stable and last indefinitely as far as mine go. I've seen much later diesel engines that I've acquired start falling apart like that. But my 0-4-0's seem pretty solid at the moment.

The same goes for plastic and other materials they use in model railroad equipment. Sometimes they go bad in just a decade or two, sometimes they last for what seems like forever.

I had posted this before. Worth doing if having Aristocraft HO mailed to you.
"If you do buy one of these locos via Ebay or other shipping method I recommend that you ask the seller to please wrap the engine and tender in bubble wrap or other padding. Everyone that I have gotten that was left in that display box arrived with either broken tender trucks or some other broken area. The original box does not support the items well and they bounce around. Also look for warped frames on the 4-6-0 Camelbacks and Atlantics."
