O-RING (Doosan DWA145089)

A damaged retaining ring can allow assembled components to separate unexpectedly, leading to mechanical failure. During inspection, a retaining ring may show signs of deformation or cracking that compromise its holding force. Keeping a retaining ring in sound condition helps maintain the correct axial position of parts within an assembly. This aftermarket replacement part references the Doosan catalog and carries the part number DWA145089. The part type is a retaining ring, which functions as a mechanical fastener that seats into a groove to secure components. A common failure consequence is that a worn or broken ring can release a shaft or bearing, causing misalignment or jamming. Verify the serial number or application, then call (562) 693-7748.
