O-RING (Komatsu KO3EA-61-12160)

KO3EA-61-12160: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. This aftermarket replacement part references the Komatsu catalog number KO3EA-61-12160. The retaining ring functions as a mechanical fastener that seats in a groove to secure parts on a shaft or in a bore. When a retaining ring loses tension or breaks, the retained component may shift or dislodge during operation. In a typical repair scenario, a worn or corroded ring is replaced to restore secure positioning. The ring is a simple, non-sealing component that relies on its spring-like grip to hold position.
