During inspection, a lock ring may show deformation or cracking from repeated load cycles. Keeping a retaining ring in sound condition helps maintain axial positioning of assembled parts. This aftermarket replacement part references Doosan as the OE maker and cross-references part number DWA138552. The ring functions as a mechanical fastener that seats in a groove to secure components. A common failure consequence is that a broken ring can release a retained part, causing sudden disassembly.
