🔹Product Overview

This connecting rod bushing, part number 6211‑31‑3130, is a vital sliding bearing part designed for Komatsu 6D140 diesel engines. It is installed on the small‑end bore of connecting rod, reducing friction between connecting rod and piston pin while bearing strong reciprocating impact load during engine operation. Our aftermarket bushing is made of high‑strength copper‑alloy material with precision machining. Every item has passed strict dimensional tolerance, roundness and surface wear‑resistance inspection. It is a perfect replacement component for engine rebuild, effectively solving problems such as piston pin noise, pin hole wear, overheating and connecting‑rod seizure.
