Reverse Engineering the Drill Motor

Is anyone out there reverse engineering the drill motor? I’m still trying to determine how much effort this will be and whether it is worth it.

If anyone is will to share info (i.e. gear pitch, pitch circles, output shaft designs, etc) I would appreciate it.

we unintentionally took one of the gear boxes apart and had a hard time getting it back together. The question about this is is it completely nessicery to take the rool back pins out this year…but if I were you I wouldn’t mess with it it seems to be too much trouble.
