Sanddrag: you can get the new gear from pretty much anywhere. I ordered oen from Motion Industries yesterday. Im guessing they press fitted it onto the shaft of the drill motor. As to how they got it off, search. I remember Paul Copioli posting a neat little machined piece that you made, then screwed an M5 screw through, eventually popping the pinion off the shaft.
