Complete rear rim for Komatsu HD4056

The complete rear rim, part number 5663073200, functions as a structural subassembly within the undercarriage of heavy-duty transport equipment. It provides the necessary mounting point for rear tires and integrates with the axle assembly to facilitate the transmission of engine power for vehicle traction. This component is engineered to maintain wheel alignment and support the load-bearing requirements of the machine during operation.

This assembly is designed specifically for the Komatsu HD4056 haul truck. It typically includes the wheel hub, wheel studs, and interfaces for braking or suspension systems. The component is built to manage the mechanical stresses of torsion, bending, and compression experienced by the rear axle assembly during transport tasks.

Rear rims act as the primary connection between the drivetrain and the ground, ensuring that torque is effectively applied to the tires. By housing the wheel mounting hardware and supporting the weight of the machine, the rim assembly ensures stability and mobility. Precise fitment of this component is necessary to maintain proper wheel geometry and to prevent uneven wear on tires and drivetrain parts.
