Shim for Bucyrus 4100XPCAC

The shim, part number R61522D4, is a precision component used within mechanical assemblies to manage tolerances and spacing between machine elements. It is utilized to compensate for wear, align rotating or static components, and establish the correct clearances required for the mechanical systems to function within the manufacturer's specified limits.

This component is compatible with Bucyrus and P&H 4100XPCAC and 7495HR2 mining machines. It is engineered to meet specific dimensional requirements, featuring an outer diameter of 19.00 inches, an inner diameter of 10.125 inches, and a thickness of 0.1793 inches. These dimensions ensure proper fitment during the maintenance of transmission and rotation assemblies in these large-scale mining units.

In heavy machinery, shims serve as critical spacers that allow maintenance technicians to fine-tune the interface between mating parts. By providing a precise adjustment of the gap between components such as gears, bearings, and housings, shims help maintain the intended mechanical alignment. Proper use of these components prevents excessive play, misalignment, and uneven load distribution, which are necessary to maintain the operational integrity of the machine's drivetrain and structural assemblies.
