WASHER (Doosan DWA133937)

DWA133937: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the Doosan catalog number DWA133937. The washer acts as a load-distributing spacer between a fastener head and the mating surface. Its primary mechanical function is to prevent galling and distribute torque evenly. A common failure consequence is fastener loosening under vibration, which can allow components to shift. Verify the serial number or application, then call (562) 693-7748.
