I new to this forum,so please excuse me if i post what seems like a stupid topic or something that sounds stupid but iam a novice railroader thats just returned to the hobby after a 35 year abscentence,is the power truck or motor that tyco put into theyre trains in the 70s and 80s the same or similar to what they used in the slots cars they made during the same time period? can older mantua drives be used to replace the power trucks or motors 70s or 80s? can the tyco shells be changed over to another frame or brand name?bachmann seems to be a similar setup frame wise,just curious if anybody has considered this

Contact BriansTyco. I'm working on a Repowering project but it's in the embryonic phase.
Of course another chassis can be used. One of our guys has put a Super 630 on a Stewart Chassis and of course it runs teriffic!
Anything is possible have a look in the forum or do a search under power Torque or repower.
Cheers,
Gareth

Tyco's "powertorque" train motor was NOT the same as Tyco's slot cars motors of the same era, although some have speculated that it IS in fact similar to older slots from another manufacturer; I'm not a slot car buff so I don't know myself.
As for swapping the drives: The Switcher, F-7/9, GP20 and C430 were made in both Mantua-motor and powertorque versions; you can conceivably swap them in many (but possibly not all) cases with little to no effort. You could probably swap motors to other diesels to (SD24, E9, 630, Shark) if you're willing to work a few kinks out - might not be snap-in-and-go easy, but not terribly difficult either.
BriansTyco put a Super630 on the Stewart Chassis, as a drop-fit. I put a Shark on an Athearn F-unit chassis that was slightly (and easily) modified. I imagine the sky is the limit, it just depends on what you've got lying around and are willing to try.

Who made AFX slot cars. Thats the motor/magnet combo this resembles!

| I believe Aurora came out with them, and it passed on to Tomy. Somehow I think the AFX name survives today. I haven;t seen any of them myself. Somehow, I just can't see that big PT armature crammed into a slot car. Or are you saying the basic design concept is the same (just a different size)?

Nope that exact one. I have a AFX Datsun Baja Pick-up somewhere I can open and photograph. It's exactly the same size I bet.

I had both Aurora AFX and Tyco Slot cars as well as the trains.
The AFX cars did use what was called a "pancake" motor. The size of the armature was identical to the PT.
I did attempt a repower of a PT F-9 with an AFX car, took two cars actually. I found that some of the AFX pancake armatures had a thicker, shorter shaft, while some had a similar size shaft as the Tyco PT. The brushes were the same but the springs from the AFX slot car were much shorter than the PT springs. I was successful in replacing the armature, however, the winding design was apparently very different. It just didn't have any pulling power. I am sure AFX didn't have the idea of pulling power in mind when they spec'd the armature. Fortunately, that was the only Tyco loco that I had ever experienced a shorted armature on. By the way, the Bachmann pancake motor of the period, while the same width armature was too thick (even more robust than the PT) and the shafts where not long enough.
Those little AFX cars could generate a lot of RPM and since those cars were so light, they were quite fast. But the Tyco PT armatures were much more robust. They literally generated a lot of torque.
On a side note, I recall that as a kid, I would over oil the bearings....as I am sure a lot of kids did. The solution I discovered to get the oil out of the armature and brushes was to soak the entire PT truck in rubbing alcohol for about 30 minutes. I even ran the motor while in the alcohol (though I wouldn't reccomend it now) and due the centrifugal force, caused better penetration of the alcohol and slung out the contaminating oil. Once completed, I would put a tiny, tiny bit of oil on the bearings and a bit of grease on the gears and wheel sets.....the loco ran like new. I was amazed. I should note, that this also worked on the Life-like single pole motors and Bachmann pancake motor. However, the old Life-like single pole motor, in my experience was junk and nowhere near as strong as the Tyco PT. The Bachmann pancake motor just wouldn't die. I know, I tried to kill one as a kid (for some reason, I just hated that loco at the time). Ran it to death, reversed while at full throttle forward many times[:o], that little F-7 just came back for more.[}:)]
Ahh, I just love the sound the PT makes when running correctly. It was always such a sweet, quiet whine. But I digress.[:D]

I also thought they looked similar.
