About This Product
Setting the maindrive gear bearing to the correct factory depth is crucial for the longevity of a 4-speed transmission. This Jims tool is specifically for 1979 to 1986 4-speed Big Twins and is used to install the bearing matching OEM 8905 for late 1977 to 1981 models, or OEM 8906 for 1982 to 1986 models. By ensuring the bearing is seated at the exact depth required by the factory, you prevent alignment issues and premature wear on the gear set. It is a precision-machined tool that takes the guesswork out of transmission assembly, making it a staple for anyone rebuilding these classic gearboxes.
