so as it stands now my Ph 1 630 has been remotored and now is at my LHS to get the DCC installed, I'm super exited to get the beast up and running, and now I have converted my clementine frankentender with a donated 70 ton DCC drive (the newer one)
so my brain gets going on all my "failed" PT repairs and upgrades over the years and then it hit me....
what if I redesign the PT to take a vertical can motor?
and what if I build these as replacements on Tyco engines?
I'm pretty motivated to try this but interested on the forum's thoughts and imputs, I'm thinking of starting maybe in a month (gearing up for my two week annual training as well as waiting on my paycheck to start)
either way, I'll start on a vampire truck mock up and hopefully see where that goes

so, you're going to redesign the whole truck, or try to modify the existing one? Putting in a low profile can motor has worked so far, but mounting one vertically would be quite a feat. The gears run counter to that positioning, so how would you make that work? Any repower for Tyco would probably be most welcomed if it was doable.  And fairly easy.

as it stands now, it'll be a redesign/rebuild of the existing one
as it looks now it'll be the Nichibo pc-130 motor mounted vertically and drive the center truck which I've installed a gear from my Athearn parts box...I'll do some concept shots soon

so here's what I have so far:
the project as it stands now:
first thing would be to "gut" everything but the bolster mounts
Pt before the mill
then the millwork ala my quick and crappy Photoshop
next I'd have to make a "keyhole to clear the new gear and worm
before the shop
and why I'm not on the Iranian ministry of propaganda
so when that is done this is what the "towertorque" should look like (and why I don't do UFO hoaxes )
hopefully I should have some progress this week that is If I can get the OK in the Machine shop do fiddle around on my lunch with this!

I actually had a very similar idea a while back, but I tried making the truck frame from scratch. I used Athearn gears, brass sides, a plastic center, and a motor about the same as yours. Got some of the holes drilled wrong, so it doesn't work especially well. It is all wheel drive and electrical pickup, though. I really need to try rebuilding it.
Hope you can get yours figured out!

Have you considered milling down the P/T frame and mounting the motor with the shaft parallel to the rails and using a worm that would mesh with the original large gear on the P/T.

Ok, so that LOOKS like a viable concept. The drilling and milling will need to be precise to locate the worm gear, but I don't see anything wrong with the concept. Looks like you'll lose one powered axle of the 3, but a small sacrifice for a more reliable motor. I like it, hope it works out.

Metalsmith: yes I did think about that, however the way that concept was it seemed too complex I've always looked for simple
Jerry: actually no. with the original PT the center wheel is the primary drive wheel in the TT (or FT or UPT) center wheel still is

A little progress
First I used a hacksaw to trim off the top....
Then I used the shop grinder to make my notch, so far so good....
Gears fit, and still rotate freely, however they may be too high to seat the motor the way I want it, and OF COURSE I didn't bring the motor to test fit!  well I'll just wait till I get home
Still, I'm liking where this is going....I think I'm onto something....we shall see....

Chief:
I think you'll have a hard time getting precise location with the tools you have. This isn't a problem. You can substitute fitting for precision.
Concentrate on getting the ground-out sides 'vertical' and 'square' with the axle slots. Then devise some sort of flat-curved 'saddle' pieces and attach them temporarily to the curved sides of the motor, leaving some room for shims. Shim / file and shim until the mesh is right, then glue the saddles in place. This should give you a perfect 'mounting bore' for the motor, if you go slowly and take care.

| I'm pretty excited about this project and I really hope that it works out. this is one of those wish list things that I used to think about doing when I was a kid and I got frustrated by the way my Tyco units ran. If it works for you, imobe copying one for myself

It may be better than the CD rebuild even though it's a tad more labor intensive. But if it works....it works, gonna dremel the holes tomorrow with any luck!

I just had an idea. Use NWSL PDT drives with right wheel base that will match the old trucks and reuse those. A new frame would be needed and added a lead weight for traction. They're expensive as all get out! Then DCC could be added if desired.

This will definitely be more robust than a disk drive motor repower, but how are you going to make the motor clear the idlers and still have it clear the shell? This motor would definitely be too tall for the tender drive.

that is the next hurdle indeed! I may wind up tilting the motor in a bit to stretch the shaft. I'll see how it goes tonight

| Hey now there is an idea. If the motor were installed at an angle it shouldn't effect how it meshes with the worm gear and it would allow the motor/frame package to take up less space. It might even open the door to using a dual shaft motor with a modest sized flywheel on the top.

Did you get any further with this? Really like this idea. I have a number of PTs that need to be remotored and this looks like a great idea!

No sadly, with my brother's wedding, the house went through an overnight "purge" and PT project eleventybillion vanished along with a good number of my C630 shells. I don't THINK they were tossed in the round file, just misplaced in the "hobby shop stockroom" that is/was the hobby corner :(

Hope you find them eventually. I know how things can disappear when things get moved around. Once we get moved into the new house and settled, I wouldn't mind trying to bring your idea to fruition. Might try using DSF's favorite material (brass) and see what we can do to bring these old PT trucks back up to speed.
