Part No. 800345910-83513200, wheel reducer assembly for wheel loader wheel-end drivelines.
Component position: Mounted inside the wheel hub, it serves as the final speed-reduction and torque-multiplication unit in the driveline, directly affecting the machine's ability to start and move under heavy loads.
Core function: Converts high-speed, low-torque input from the drive axle into low-speed, high-torque output, providing sufficient wheel traction for loading, climbing, and heavy hauling operations.
Structural principle: Employs a planetary gear train with sun gear input, planet carrier output, and fixed ring gear, achieving a fixed reduction ratio through multi-stage gear meshing in a compact, high-load-capacity design.
Fit and installation: Manufactured to OEM specifications for direct replacement on ZL-series loader axles. No modification or adapter required—bolt patterns, spline parameters, and external dimensions match the original unit.
