RING - BACK UP (Doosan DWD501718)

DWD501718: A damaged retaining ring can allow a shaft or bore component to shift out of position, leading to mechanical failure. During disassembly, a back-up ring may be found deformed or cracked from repeated load cycles. Keeping a retaining ring in sound condition helps maintain axial location of assembled parts. This aftermarket replacement part references Doosan catalog number DWD501718. The ring functions as a mechanical stop that prevents lateral movement of a seated component. A worn or missing ring can cause unintended disengagement of the assembly under normal operating forces. Verify the serial number or application, then call (562) 693-7748.
