SEAL - DRIVE AXLE (Komatsu KO3EA-21-14140X)

KO3EA-21-14140X: A worn drive axle seal can allow lubricant leakage and contamination into the axle housing. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EA-21-14140X. The seal functions as a static or dynamic barrier between the axle shaft and housing. Its primary mechanical role is to retain gear oil or grease within the axle assembly. A common failure consequence is gradual fluid loss, which may lead to bearing damage or gear wear over time. Keeping the seal in sound condition helps prevent dirt and moisture from entering the axle. Verify the serial number or application, then call (562) 693-7748.
