WASHER - LOCK (Doosan DWD917017)

A damaged lock washer can compromise fastener security in mechanical assemblies. This aftermarket replacement part cross-references Doosan part number DWD917017. The washer type provides a locking action that prevents nuts and bolts from loosening under vibration. Without proper locking, fasteners may back out, leading to component separation or misalignment. In high-vibration environments, a failed lock washer can cause progressive loosening over time. The part is a plain mechanical component that deforms elastically during installation to maintain tension. Verify the serial number or application, then call (562) 693-7748.
