Or you could just go to a superior Classic Army replacement motor where the pinion gear is secured via a set screw.

Seriously, CA motors are in fact better than TM. The TM motors are built to be completely non-user servicable with those tabs bent in to keep the end bell in place. On the CA you can remove it with two screws. The CA motor also has bearings in it - FOUR on the long model - versus none for the TM. It's still not as good as a Systema or other high performance motor, but if you're interested in motor maintenance the CA is an excellent piece of equipment.

I can post some figures if you want about efficiency increases after lathing the commutator and soldering the brush braids.
