One New Aftermarket Replacement Boom Cylinder Seal Kit for Komatsu Excavators
This aftermarket replacement boom lift cylinder seal kit restores hydraulic sealing performance on Komatsu (Komatsu Ltd.) PC-6 series excavators. The kit services the boom lift cylinder (cylinder number 206-63-02801) and includes all seals required for a full cylinder rebuild, including wiper seal, U-cup seals, rod seals, T-seal, wear bands, O-rings, and backup seals. Leaking hydraulic cylinder seals allow fluid loss and contamination ingress that can damage expensive downstream hydraulic components -- replacing the full seal kit at first sign of weeping is the recommended repair approach.
