O-RING (Komatsu KO3ED6411690)

A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3ED6411690. The retaining ring functions as a mechanical fastener that seats into a groove to secure parts on a shaft or within a bore. If the ring loses tension or breaks, the retained component may shift or dislodge during operation. In a typical usage context, a retaining ring is installed during assembly and remains under constant spring pressure. The part is a simple circular clip made from formed metal, relying on its snap-in engagement for retention. Verify the serial number or application, then call (562) 693-7748.
