SEAL - OIL (Komatsu KO34C-21-13240)

KO34C-21-13240: A worn oil seal can allow lubricant leakage, leading to increased friction and potential component damage. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO34C-21-13240. The seal functions to retain oil within a rotating assembly, preventing contamination from entering. A common failure consequence is gradual oil loss, which may cause overheating or premature wear of adjacent parts. In typical usage, a seal that hardens or cracks over time will lose its ability to maintain a tight barrier. The item ships at approximately 0.32 pounds.
