Connecting rod bushing for Komatsu GD511A

The connecting rod bushing, part number 6207-31-3130, serves as a bearing component within the internal combustion engine. It is installed in the connecting rod to provide a smooth surface for the piston pin or crankshaft journal, facilitating the necessary rotational and oscillatory movement during engine operation. This component is essential for the transmission of forces from the piston to the crankshaft.

This part is compatible with the Komatsu GD511A and GD511A-1 motor grader models equipped with the S6D95L-1 engine. It is engineered to meet the specific dimensional requirements for these engine assemblies.

In heavy machinery engines, connecting rod bushings act as the interface between moving parts, allowing the connecting rod to pivot while maintaining alignment. By providing a controlled clearance, these bushings manage the load distribution and support the lubrication film required to prevent direct metal-to-metal contact between the connecting rod and the pin or journal.
