O-RING (Komatsu KO3EA-63-11190)

KO3EA-63-11190: A damaged retaining ring can allow assembled components to separate during operation, leading to mechanical failure. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO3EA-63-11190. The retaining ring functions as a fastener that holds components in position on a shaft or within a bore. Its plain mechanical function is to seat into a groove and prevent axial movement of the installed part. A concrete generic failure consequence is that a worn or broken retaining ring may cause the retained component to shift, resulting in noise or loss of function. Keeping a retaining ring in sound condition helps maintain secure assembly under normal working loads. Verify the serial number or application, then call (562) 693-7748.
