Product Description

HD90129320019 HD425 Passive Cylindrical Gear heavy-duty truck parts


Engineered for Shacman’s Rigorous Performance Demands

Exclusively designed for Shacman heavy-duty trucks, the HD90129320019 HD425 Passive Cylindrical Gear matches original vehicle specifications with pinpoint accuracy. Machined from high-strength alloy steel with precision heat treatment, it features a precisely cut tooth profile that ensures smooth meshing and stable torque transmission, withstanding extreme rotational forces and heavy-load friction in the drivetrain system. This gear integrates optimized structural thickness and reinforced tooth roots, eliminating stress concentration points and effectively reducing wear, noise and vibration during high-speed operation, protecting adjacent transmission components from premature damage and ensuring reliable drivetrain performance for Shacman trucks in harsh working conditions.

Key Application Scenarios & Purposes


  • Core fit for Shacman HD425 series heavy-duty trucks: Specially adapted for Shacman HD425 tractors, heavy cargo trucks and dump trucks, perfectly matching the vehicle’s transmission/axle system structure for seamless assembly without secondary modification.
  • Heavy-duty transportation & engineering operations: Widely used in long-haul intercity logistics, mine material haulage, construction site earthwork transportation and off-road engineering scenarios, stable under high-load, frequent start-stop and complex road conditions.
  • Drivetrain torque transmission core component: Serves as a key passive gear in the truck’s transmission/axle system, cooperating with active gears to realize precise speed and torque conversion, ensuring efficient power delivery from the engine to the wheels.
  • Drivetrain system protection & stability improvement: Ensures smooth meshing and low-noise operation of the gear set, reduces mechanical wear of the drivetrain, improves the overall stability and service life of the transmission system, and lowers the failure rate of heavy-duty truck powertrain in long-term operation.
