One New Aftermarket Replacement Arm Bushing for Komatsu PC-Series Excavators
This aftermarket replacement bushing fits the arm (dipper) linkage assembly on Komatsu (Komatsu) hydraulic excavators, providing a precision-fit sleeve between the arm and connecting pins. The bushing controls articulation at the arm joint, resists wear from heavy digging loads, and helps maintain correct alignment throughout the working cycle. Replacing a worn or damaged bushing restores smooth arm movement and protects surrounding pin and bore surfaces.
