SPRING (Komatsu KO3EA-36-11181)

KO3EA-36-11181: A worn retaining ring can allow assembled components to separate during operation, leading to mechanical failure. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO3EA-36-11181. The retaining ring functions as a fastener that holds parts in position on a shaft or in a bore. Its plain mechanical role is to seat into a groove and prevent axial movement of the installed component. If the ring loses tension or breaks, the retained part may shift or dislodge, causing sudden loss of function. In a typical repair context, a technician replaces a retaining ring when disassembling a joint or bearing assembly. Verify the serial number or application, then call (562) 693-7748.
