O-RING (Komatsu KO3EA6413210)

KO3EA6413210: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure or loss of function. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EA6413210. The retaining ring type functions as a mechanical fastener that seats into a groove to secure parts on a shaft or inside a bore. A common failure consequence is that a worn or missing ring permits axial movement, which can cause misalignment or disengagement of adjacent parts. During routine service, a retaining ring may be found cracked or deformed from repeated stress cycles. Keeping a retaining ring in sound condition helps maintain the intended assembly integrity. Verify the serial number or application, then call (562) 693-7748.
