I'm not sure , David. I'll have to check that with my DCC guy.
However, I did manage to mount the motor/compound gear assembly tonight.

I used a piece of .03" or .7mm (for us Canadians) of styrene to shim the assembly up to the point where everything meshed smoothly and there was acceptable gear lash between the compound and drive gear.

I ran it carefully for a bit in both directions and didn't detect any binding.

to fully isolate the motor from the chassis I had to use a plastic Kadee coupler mounting screw to attach the compound gear mount to the frame. I hope that the plastic screw is up to the task in the long term.
