🔹Product Overview

This connecting rod Part No.6151‑31‑3111 is a critical force‑transferring component specially engineered for Komatsu 6D140 diesel engine, widely fitted on Komatsu excavators and heavy construction equipment. It transmits the thrust from piston combustion to crankshaft, converting reciprocating motion into rotary motion. It bears tremendous alternating impact load and mechanical stress during long‑time heavy‑duty operation. Damaged connecting rod will lead to engine knocking, abnormal vibration, even catastrophic engine failure. Our aftermarket connecting rod is strictly manufactured, forged and machined in accordance with original OEM standards, stable and reliable for direct replacement.
