The top of the pinion should be 0.540 to 0.570 inch from the face of the motor. Unfortunately, due to variation in shaft length and boss height on the motors, the only thing you can reliability measure from is the face of the motor. When using our RS-545 motor, you should push the pinion onto the shaft as far as you can without it touching any part of the boss or bearing on the front of the motor. The shaft should never be proud of the pinion, if it is you will need to shorten it so that it is not.

I believe that this binding can happen to the 36mm and 42mm gearboxes as well. Team 86 had a motor issue last season similar to the one described by Travis in Post #10 with a 42mm unit. Does a similar measurement (0.54" to 0.57") exist for mounting pinions for these smaller gearboxes?
