Fast Gearbox One Shaft 19694-49

19694-49 is the genuine input shaft (one shaft / first shaft) assembly for Fast (Shaanxi Fast Gear) heavy-duty manual transmissions, widely used on domestic heavy trucks such as Shacman, Foton, Sinotruk and Dongfeng. It is the primary power input component, transferring engine torque into the main gearbox and meshing with gears and synchronizers to complete gear shifting and high-torque power transmission. Made of high-strength alloy steel with precision forging and carburizing quenching heat treatment, it has high torsional rigidity, wear resistance and fatigue resistance, adapting to long-distance heavy haulage and severe vibration conditions, solving spline wear, shaft bending, abnormal noise and shifting failure faults.
