My team bought a P60 to fix our intake and it came with one of
these gears. Because it has a 5mm bore and the motor has a 5mm shaft, we assumed everything would work out. In reality, the gear didn't slide nicely onto the shaft and we ended up malleting the gear in, which broke the 775pro in the process (i.e. it stalls when power is applied to it). Is there a proper way to get this gear on the 775pro?
