Genuine OEM Certification
Genuine OEM Certification All parts strictly follow Sinotruk’s original manufacturing standards, using high-strength alloy steel materials, and passing more than 1000 hours of fatigue testing to ensure perfect matching with the original vehicle gearbox, avoiding transmission failures caused by improper adaptation of counterfeit parts. Core parts include synchronizer rings, main shafts, clutch boosters and other key components.
12-Speed Transmission
12-Speed Transmission Advantage The HW19712 gearbox adopts a 12-speed manual transmission design, with a wider gear ratio coverage. It can provide strong starting torque and efficient cruising speed at the same time. The maximum input torque reaches 1900N·m, which perfectly matches the 371HP Weichai engine, meeting the heavy-load transportation needs of 21-60 ton heavy trucks.
All-Condition Adaptability The parts have super strong environmental adaptability, passing the high and low temperature test of -40℃ to 60℃. The seals are made of oil-resistant rubber materials, which can resist dust and mud erosion. The synchronizer adopts a lock ring design, reducing the shifting force by 30%, adapting to the extreme working environment in high-temperature and dusty areas such as Africa and the Middle East, and is widely used in dump trucks, tractors, mixers and other heavy truck models.
Extended Service Life Design Key components adopt modular design for quick maintenance and replacement; the gear precision reaches ISO 6 level, and the transmission efficiency is increased to 96%; the lubricating oil circuit is optimized to ensure full lubrication of each component. The average service life of the parts is 25% longer than the industry standard, which greatly reduces the user’s maintenance cost.
