Hub back plate for FMC Link Belt HC-258

The hub back plate, part number 3J1733, functions as a structural support and mounting surface within the axle and wheel assembly of the machine. It provides the necessary interface for securing components such as bearings, seals, and braking system elements, ensuring the alignment and stability of the wheel or crawler assembly.

This component is engineered for the FMC Link Belt HC-258 lattice boom truck crane, including units with serial number 28G5-679B. It is designed to interface with the specific geometry of the axle system to maintain the integrity of the hub assembly during operation.

In heavy machinery, a hub back plate acts as a foundation for the rotating components of the axle. By providing a rigid mounting point, it helps manage the forces transmitted through the wheel assembly, supporting the load and maintaining the correct positioning of internal mechanical parts.
