Threaded Screw
 

I have managed to thread the screw that holds the pinion in place on the motor. Any idea how I can get it out? Just a simple and easy way if possible.

do you mean that you stripped the screw's tip

the more professional way will be to purchase a 'kit' from hardware store where there is a device that you thread a hole in a different direction and then 'unscrew' the another direction. never tried it but i google them

so far my simple way of getting getting a handdrill... reverse the direction (i.e. the drill turn anti clockwise).........press hard against the screw and stat the drill..... once you manage to get about 3-5mm or so out... u should be able to use a small tip plier to remove the screw. (the vibration of the drill when you press hard on the screw does 'loosen' the screws' grip and start to turn

use the above method couple of times and succeeded (so far so good) :D:D

hope it helps... my 2 cents

I'd probably use some needle nose vise grips to grasp the pinion so it doesn't turn on you. The pinion is shot anyway, right. Loose a pinion rather than the motor or roller. Then use the dremel with a cutoff wheel and cut partially though the pinion. Cut a few slots in the pinion without letting the pinion cool off. Since the pinion is a soft metal it will swell up fast and basicly fall off the motor before you hit the rotor anyway. Good luck! :)
