WASHER-HARD (Doosan DWD917178)

DWD917178: 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 DWD917178. The washer type distributes load evenly under a fastener head or nut. A plain mechanical function is to prevent galling between the fastener and the mating surface. A concrete generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the softer material, reducing preload. Keeping a washer in sound condition helps maintain consistent torque retention in assembled components. Verify the serial number or application, then call (562) 693-7748.
