I noticed axial movement if I rock the 1st gear on wheel shaft (tallest gear) in two different sets of gears I own. Also, if I rotate the transmission, both shafts completely seated in case - gears meshing, and abruptly change direction, I can hear the gears clinging together. Such that I believe the gear is hitting against the adjacent gear.
Do you know where I can source a replacement bronze gear bushing?
