Connection bushing for P&H 4100-XPB

The connection bushing PLNMMPP&HBAL85 serves as a critical pivot point within the short tie rod assembly of the 56 cubic yard bucket on P&H 4100-XPB mining shovels. It facilitates the necessary articulation and load transfer required during heavy excavation and material handling operations in open-pit mining environments. By providing a precise interface between the tie rod and the bucket structure, the bushing maintains alignment and supports the mechanical forces applied to the digging components.

This component is engineered to the specified dimensions of 9-5/8 inches outside diameter, 7-1/2 inches inside diameter, and 7-1/2 inches in length. It is intended for installation on both the interior and exterior ends of the short tie rod connection. The part is manufactured according to the MMP-P&H-BAL166 specification to ensure it meets the dimensional requirements for the P&H 4100-XPB model. Regular inspection of this bushing is necessary to ensure the structural integrity of the bucket linkage and to prevent excessive play in the pivot assembly during operation.

Bushings of this type act as replaceable wear surfaces in heavy machinery, protecting more expensive structural members from direct friction and impact damage. They are typically installed in high-load pivot points where rotational or oscillating movement occurs, allowing for controlled motion while distributing operational stresses across the connection interface.
