I also remotored one of my Athearn PAs.
I had to mill the frame for the Mabuchi motor to fit and make bushings to adapt the drive couplings.
The gears in the trucks were seated in valve grinding compound. disassembled, cleaned, lubed and reassembled.
I also made a stabilizer to keep the chassis from rocking on the trucks and shorting on the metal sideframes.
