The Eaton Fuller input shaft assembly, part number S-1659 or S1659, is the front shaft that carries engine torque from the clutch into the transmission gearing. As an input shaft assembly, it engages the clutch disc splines and transmits drive to the countershafts inside an Eaton Fuller gearbox. Order it by the exact part number to match your transmission model, since input shaft spline counts and lengths vary across Eaton Fuller series.
