[PAR_WIG1350]

If you could cut the rod off to expose the shaft (if you're careful you'll only loose a millimeter +/- a bit)and heat the remaining rod section while cooling the motor with compressed air, the remaining shaft portion could be removed with a conventional gear/pinion puller (the kind that pulls the gear and pushes the shaft, if you push against the motor can you could crush a spacer [yes, I have done that before]).

Better yet, you could heat the shaft before cutting it. That could reduce the risk of motor damage.
