This piston pin steel bushing (connecting rod small end bush) is exclusively for Dongfeng Cummins 6BT/6CT engines, installed inside small end bore of connecting rod, acting as wear-resistant bearing base for piston pin rotary movement. It is precision bored and honed from wear-resistant alloy seamless steel tube with high concentricity of inner & outer circle. Honed oil storage texture on inner wall retains lubricating oil continuously to reduce friction loss of piston pin. It separates connecting rod body and piston pin under reciprocating impact load of piston, prevent direct wear and scrapping of connecting rod small end. Outer diameter, inner diameter and length are precisely machined per Cummins OEM standard, cold press fitted during used loader engine overhaul, matched with piston, piston pin and piston ring as complete overhaul kit. Fit 5-ton used loaders with Cummins power for overhaul maintenance and complete machine export matching.
