Title say's it all..

I am in need of motor for the Aristocraft Class 66.
I need to remove (and strip-down) the bogie, but I have a loco which draws 3Amps-plus, and a smoking motor! :eek::(

Possibly, our Friends States-side, will have more luck in locating one of these?

Thanks,
PHilP.

Same motor block as the SD45 of course, but not much evidence of any of these being around either - only "sold out" messages.
Can the motor be stripped down and the commutator serviced/cleaned, or has a coil insulation failed maybe?

You'd think there must be a motor out there of similar spec, I doubt the Aristo motor was specifically made for them.

Except they were made .. ?30-40? years ago.. ?? :eek::(

Perhaps, Greg'knows a man who would know? :think:

I *suppose* if all-else -fails.. I can strip both bogies, Leave the centre axle free-wheeling, and drop four axle-hung units in?? - That would give me four powered-axles. Get round the articulation problem. AND probably get rid of that 'orrible whirring noise they make.. :think::think::)


I wonder if G-Bits might have one?? :think:

I'm not completely knowledgeable about the trucks on that loco, does make sense standard 3 axle Aristo truck.

I might do know a guy, but to be sure can you give me the axle spacing, and also the tread diameters?

I might also know a guy with stainless steel replacement wheels, although they have finer flanges, so could be a problem on some trackwork.

Phil send me an email, let's see what I can do.. my suggestion is pull the motor block apart, if you have not ever done so, I have a page on them on my site, under MOTIVE POWER... ARISTO .... PRIME MOVER

I think you will find the standard 3 axle AristoCraft motor block has two motors, making the loco four motored.
This might be helpful when working on the motor block.

Yep!
Two motors, and three gearboxes..

I can't quite field-strip them blindfold.. But I do seem to have taken many of them apart to clean / lubricate.

Greg's page is invaluable, the first couple of times.. :):rock::clap::clap:

The tricky part is unsoldering the motor tabs without melting the motor block housing and/or damaging the motor brushes by overheating the tab.

I updated my web page to specifically address disassembly, I noticed I had not done this, and I also cleaned up the page a bit.

When did Aristo fold? Not 10 years ago yet, is it? I certainly didn't buy my 66 and SD45 30+ years ago

Yebbut nobbut - some of Aristo's offerings were not upgraded, but some were. I think the SD45 had an upgraded gearbox because it was a newer model, the C16 was rev-vamped, but I'm not sure how many others were, and as per Phil's comment earlier - 2 motors, 3 gearboxes - those would have been the original design I think.

The SD45 was the first loco with the "prime mover" type of gearbox (the modular gearboxes driven by a hex shaft with the sliding axles
... Aristo always called it the "prime mover" type... so I keep calling it that type.

It is a completely different design from their 2 axle diesels and the steamers... The modular gearbox was introduced to their steamers with the second version of the Pacific.. or the first version of the Mikado, not sure.

from my site: (might be a few errors)

Hard to believe my FA-1's with the end play adjusting screws are that old.
Street prices were quite reasonable when those were introduced.

Bachmann now sell the 2 axle trucks, I'm not sure if the motors are the same or not.
