So my team somehow was able to snap the shaft off while running a 775 Pro. We had an AM 12t Pinion on it when it snapped, connected to our drivetrain. For those teams that ran 775 drivetrains last year (2767, 2451, 3357, etc.), did you ever discover any failures similar to this?
We at first believed it was due to a lot of sudden forward and then reversing while driving but later we remembered our gearboxes became loose at one point and we are wondering if the sag of the motors put too much stress on the pinion, later causing it to fail. The pinion has an unusual wear pattern on it (flat teeth in a few spots but we have an enclosed gesrbox so could be due to getting wedged somewhere after failing).
And by the way, the motor still runs.
