Pinion Screw STUCK
#5
"Micro" screw extractors, I believe, will get as small as a 3mm screw out. If anybody finds a "Super Micro" extractor set, let me know.
There are all kinds of pinion gear pullers you can buy. If you are in a hurry, just drill the grub/set screw out. Just be sure to have some extra bits handy .

9 times out of 10 I've had a pinion I couldn't remove it's been an allen wrench problem. I carefully grind back the end of the wrench to make sure there is no rounding of the flats and retry. Next thing is to try flattening the wrench slightly and drive it into the set screw and try to get it to turn. I might also try heating the pinion first, but if all this fails, just tape up the motor and grind the set screw out with a fiber reinforced cut off wheel on your Dremel tool. Sacrifice the pinion for the motor.
