Based on what you have posted, it sounds like the pinion is extending too far into the gearbox and causing it to bind resulting in the high current draw. 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.

When tightening the 4 screws holding the gearbox together, ensure that you tighten them evenly like you would tighten the lug nuts on a car wheel. If you pull one screw down tight with the others loose, the blocks will not be square with the ringear.

The current P-60s are not designed to be face mounted, we simply didn't feel we had room on the face of the front block for mounting holes. We plan to offer a version that can be face mounted, but it will not be in time for this FIRST season.

We have thought of a couple ways you could possibly face mount the current version.

1 – Face stud mount: You could use longer lengths of 6-32 all-thread in place of the screws. Screw the all-thread into the back block and let it extend through the holes in the front block. Use nuts on the front of the front block to tighten the the gearbox together. The all-thread extending from the front provides studs to face mount with.

2 – Screw through mounting: You can use the 4 screws holding the gearbox together to also mount it. You will need screws long enough to extend through what you are mounting to and into the back block. As long as all 4 screws pull the back block up tight against the front block (and the front block up against your mount) you should be OK.
