O-RING (Komatsu KO3EA-61-12450)

Keeping a retaining ring in sound condition helps prevent unexpected disengagement of critical parts. This aftermarket replacement part references the Komatsu catalog number KO3EA-61-12450. The ring functions as a mechanical fastener that seats in a groove to hold components axially. Verify the serial number or application, then call (562) 693-7748.
