The Center Joint Seal Kit for Komatsu PC200-6 is a complete hydraulic swivel joint seal kit designed for repair and maintenance of the center joint (swivel joint) on Komatsu PC200-6 excavators. This kit provides complete replacement of sealing elements to restore the swivel joint's ability to transfer hydraulic oil between the upper structure and undercarriage during 360° rotation, preventing oil leakage and ensuring stable travel and swing performance.
Product Overview
The Center Joint Seal Kit is specifically engineered for Komatsu PC200-6 excavator center joints, widely used in heavy construction, mining, and earthmoving applications. The center joint is a precision component that transfers hydraulic fluid from the stationary source to the rotating parts of the machine, maintaining pressure for travel, swing, and attachment functions during continuous rotation .
Over time, the seals within the center joint wear out due to heat, pressure cycles, contamination, and normal aging. When seals fail, hydraulic oil leaks, pressure drops, and the machine may experience travel deviation or loss of swing power. This seal kit provides all necessary sealing components for a complete center joint overhaul in one package .
