4mm is right
Oops!

I forgot to get out the Johnson Electric catalog for the drill motor.

I thought the motor was equivalent to a 775 motor from Mabuchi. It does have the same can size (42.2 daimeter by 66 mm length), but Johnson sells the motor with 2 different shaft sizes.

Ah well...

I have two drawings from Johnson Electric, one with the 5mm shaft and one with 4mm. I THINK that the 4mm is right, but don't have a motor to mic up right now.

Can anybody get us to 100% certainty?
