KIT - FRONT SEAL/SLEEVE (Komatsu KO6736-39-1221)

A worn front seal/sleeve kit can allow fluid leakage past the rotating shaft, leading to gradual loss of system pressure. This aftermarket replacement references the Komatsu catalog and cross-references part number KO6736-39-1221. The kit includes a seal and a sleeve that work together to contain fluid along a rotating component. A failed seal often results in visible drips or a wet area around the shaft exit point. In a typical repair scenario, the old seal and sleeve are removed and replaced as a matched set. The sleeve provides a smooth, wear-resistant surface for the seal lip to ride against. Verify the serial number or application, then call (562) 693-7748.
