SEAL - UCUP (Komatsu KO3EA64A2220)

A worn seal can allow fluid leakage, reducing system pressure and causing erratic operation. The Komatsu catalog reference KO3EA64A2220 identifies this aftermarket replacement part. This seal type, a UCUP seal, provides a positive barrier between moving and stationary surfaces. Its plain mechanical function is to contain lubricant while excluding contaminants. A generic failure consequence is that a degraded seal leads to progressive fluid loss and eventual component damage. During routine service, a technician may find a hardened or cracked seal that no longer maintains its sealing contact. Verify the serial number or application, then call (562) 693-7748.
