RING (Komatsu KO3ED-63-12340)

KO3ED-63-12340: A damaged retaining ring can allow a shaft or bore component to shift out of position during operation. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO3ED-63-12340. The ring functions as a mechanical fastener that seats in a groove to secure assembled parts axially. If the ring fails or is missing, the retained component may dislodge, leading to sudden mechanical disengagement. Keeping a retaining ring in sound condition helps maintain axial retention under normal working loads. Verify the serial number or application, then call (562) 693-7748.
