Thanks, got it! I had to file away some of the thread on the ends of the pins before the body would come away from the chassis. The masking tape was to prevent the handrail lugs from popping back into the cab holes as I worked the body to and fro.
No damage done yet.
Now to wait for the motor...there is 12.5mm clearance inside the shell, I hope that's enough for the Chinese motors I've ordered (like the one TiTan used on his U30B). If not, 7.32 USD hasn't broken the bank. I also need to get a decoder in there and LEDs.

I've ordered some of the Chinese motors like the one Ian used for his U30B. They measure 47mm from shaft end to shaft end, and I measure the distance between truck centres of the GP9 at 78mm. So either end, this leaves 15.5mm for a cardan shaft and joints. Sebnitz have a 14.5mm shaft and an 11mm shaft - any thoughts on which would be better? Or I may get both and experiment.
What else should I allow for in the calculation?

The longer shaft is always better, less noisy.
You can easily change the length of the shafts, cut them in the middle and push and glue them into some corresponding plastic tube. ( Evergreen etc).

So, chassis parts ordered from Sebnitz. Some are out of stock so I'll have to see how far I can get when the first batch arrives.

Four months on and I'm finally getting round to starting on my GP9 motorisation. I have the PDF on the subject courtesy of Richard, photos from Ian's conversion and his U30B thread, all the parts I need from Sebnitz (I hope anyway), a motor, and various bits of brass, wire and PCB. Only thing to get now is a DCC decoder.
But I haven't done this kind of thing for about 10 years since building a few 3mm scale loco kits. As the man said, I may be some time.

Motorization is one of my favorite things. It can be a pain but once done it's very satisfying. Enjoy!

That's a very good point!

I also re-motor and otherwise improve off the shelf models that are not up to my standards. Piko models and the Arnold BR 171/251 come to mind.

Has anyone put a DCC decoder in their GP9? If so, which did you use?
