SEAL - OIL (Komatsu KO3EA-21-14131L)

KO3EA-21-14131L: A worn oil seal can allow lubricant leakage, leading to contamination and potential component damage. This aftermarket replacement part references the Komatsu catalog number KO3EA-21-14131L. The seal functions as a barrier to retain oil within a rotating shaft assembly. Its primary mechanical role is to prevent fluid migration along the shaft surface. Over time, a failed seal may cause gradual oil loss, increasing friction and wear on adjacent parts. In a typical usage context, seals are exposed to heat, pressure, and rotational motion. Verify the serial number or application, then call (562) 693-7748.
