SINOTRUK HOWO Truck Transmission System Parts HW19710 10-Speed Manual Transmission Assembly

The SINOTRUK HOWO HW19710 Transmission Assembly is a heavy-duty manual gearbox belonging to the truck transmission system, designed to transfer engine power to the drive axle through multiple gear ratios. As part of the SINOTRUK HW10 series transmission family, the HW19710 features a 10-speed manual configuration and is developed for commercial vehicles requiring stable torque transmission, flexible speed adjustment and reliable operation under demanding working conditions. The gearbox works together with the clutch assembly, drive shaft, differential assembly and rear axle system to complete the vehicle power transmission process. The HW19710 transmission adopts a structured gearbox design with internal components including input shaft, main shaft, counter shafts, gears, bearings and shifting mechanisms, allowing efficient power transfer from the engine to the wheels. Available specifications indicate a rated input torque of approximately 1900 N·m, a total weight of around 355 kg, and a lubricant capacity of about 12 L. During vehicle operation, the transmission is continuously affected by torque load, gear shifting frequency, temperature changes and lubrication conditions. When problems such as difficult shifting, abnormal gearbox noise, gear jumping, oil leakage or reduced transmission efficiency occur, inspection should include transmission oil condition, clutch operation, shift mechanism, bearings and internal gear components. Before ordering HW19710 Transmission Assembly, buyers should confirm the truck model, engine power range, gearbox mounting structure, clutch specification and original transmission identification information to ensure correct compatibility.
