🔹Product Overview

Connecting Rod Bushing Part No.5257363 is an important friction‑reducing inner sleeve fitted inside connecting rod small end for ISF3.8, QSF3.8 diesel engines. It cooperates with piston pin to form lubrication clearance, bears alternating impact load during engine running, reduces friction between connecting rod and piston pin, and avoids direct metal‑to‑metal abrasion. This bushing set serves as premium replacement for worn, deformed or cracked original bushings during engine overhaul, solving abnormal knocking noise, piston pin seizure and connecting rod bore damage. Each connecting rod bushing passes dimension measurement, roundness inspection and material hardness test before shipment.
