Shim for Bucyrus 4100XPCAC

The R61522D2 shim serves as a precision component for adjusting tolerances and maintaining proper alignment within the mechanical assemblies of Bucyrus and P&H electric mining shovels. By filling gaps between mating surfaces, this component ensures that clearances remain within the specified range for the equipment. It is engineered to maintain dimensional stability under the operational loads typical of large-scale mining machinery.

This part is compatible with Bucyrus 4100XPCAC and 7495HR2 models, as well as P&H 4100XPCAC and 7495HR2 units. It is manufactured to precise dimensions, featuring an outer diameter of 19.00 inches, an inner diameter of 10.125 inches, and a thickness of 0.1793 inches. These specifications allow maintenance personnel to achieve the exact spacing required during the assembly or repair of critical machine systems.

Shims are used in heavy machinery to compensate for manufacturing variations or wear between components. By providing a precise thickness, they allow for the correct pre-load or clearance in assemblies such as gearboxes, bearing housings, and pivot points. Proper installation of these components is necessary to prevent excessive movement and ensure that mechanical loads are distributed correctly across the assembly.
