During inspection, a retaining ring may show signs of distortion or cracking that compromise its holding force. The Doosan catalog reference for this aftermarket replacement part is DWMM404878. This part type functions as a mechanical fastener that seats in a groove to secure a shaft or bore assembly. A common failure consequence is that a worn or broken retaining ring can cause unintended disassembly of rotating or stationary parts.
