High Torque Bearing Kit by Baker Drivetrain®. Kit includes a precision honed bearing and seal. The 34091-85 inner bearing race has been used on Big Twins since 1985. The inner primary bearing rides on this race. By design, this race press-fits onto the transmission mainshaft. This system works fine for stock engines. 100 HP+ engines will make this race walk on the mainshaft. If it walks inboard, it will damage the maindrive gear seal and cause a transmission oil leak. If it walks outboard, it will cause a primary oil leak. Bakers high torque bearing kit eliminates this condition. Kit includes a precision honed bearing and seal
