Kobelco YY64D01002F1 Carrier Roller Assembly

The YY64D01002F1 is an upper track carrier roller (top roller) designed for Kobelco and New Holland hydraulic excavators in the 13-14 metric ton class. It utilizes sealed and lubricated bearing assemblies with hardened steel roller shells to ensure smooth track guidance and resistance to abrasive wear in demanding excavation environments. This component serves as a direct replacement for OEM part numbers YY64D01002F1, 24100N4038F1, 24100N6506F1, and SI1045. It is engineered to maintain proper track tension and alignment, reducing vibration and noise while maximizing the service life of the track chain and associated undercarriage components. The roller assembly is supplied as a complete unit ready for installation onto the carrier frame.
