According to one of our mentors/post-secondary students, there was a shipping error resulting in some teams actually ending up with a 15-tooth pinion on the FP motor, which I think might be the case as it seems to mesh properly with the AM planetary. the normal stock 19-tooth wouldn't do that would it?
If this is the case, would that mean we just need to yank the gear off (with a neighbouring team's arbor press), install the back plate then re-install it?
