SEAL - OIL (Komatsu KO3EB--21-15130)

KO3EB--21-15130: A damaged oil seal can allow lubricant to escape and contaminants to enter a rotating assembly. The seal type is a static or dynamic barrier that retains oil within a housing while excluding dirt and moisture. Over time, a worn seal may cause gradual fluid loss, leading to increased friction and component wear. This aftermarket replacement part references the Komatsu catalog number KO3EB--21-15130. The seal's primary mechanical function is to prevent leakage along a shaft or bore interface. A common failure consequence is that a leaking seal can result in insufficient lubrication, accelerating bearing or gear degradation. Verify the serial number or application, then call (562) 693-7748.
