We sheared all the teeth off of the 14t gear in the WCP 3-CIM SS. Did some naive load analysis, found that using that gearbox with 8'' wheels is really pushing the strength of the gears. Replaced the 14t gears with steel ones, did not see any more failures.

The WCP gearboxes seem to be designed primarily for 4''/6'' wheels, and using them with larger wheels is marginal. Definitely something to keep in mind for future years.

We originally had 9mm belts, and found that those ratcheted with wheels this big (FRC drive trains usually run them slightly out-of-spec even with 4'' wheels, though the specs given by Gates are for designed lifespans much longer than what anyone expects out of an FRC robot). Swapped to 35 chain, no problems there. WCP cams work like a charm.
