O-RING (Komatsu KO3ED-63-11160)

KO3ED-63-11160: 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 KO3ED-63-11160. The retaining ring functions as a fastener that seats into a groove to hold parts in axial position. A worn or missing ring may cause unintended disassembly of rotating or stationary assemblies. During service, a retaining ring that has lost its spring tension will no longer secure the mating part. Verify the serial number or application, then call (562) 693-7748. The ring is a simple, non-sealing component that relies on precise groove fit for retention.
