Eaton Fuller 21262 countershaft gear. A countershaft gear passes engine power through the transmission and meshes with its mating gears, so it has to mesh cleanly under heavy-duty load. In the factory parts list this gear sits in the countershaft assembly, two per assembly. It is printed as item 9, Od Gear-cntrshft, in the FO-16E309ALL-VMS, RTAO-11710C-AC, RTAO-12710C-AC, RTAO-13710C-AC, RTLO-12713A and RTLO-12913A, and as item 11, Drive Gear-cntrshft, in the RT-8608L and RTF-8608L. It is carried in the parts lists of many more Eaton Fuller units. Call Pro Gear and Transmission to confirm proper fit for your transmission.
