WASHER (Komatsu KO01601-00619)

KO01601-00619: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. This aftermarket replacement part references the Komatsu catalog number KO01601-00619. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical role is to prevent galling and provide a smooth bearing surface. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the softer material, reducing preload. During assembly, the washer's condition directly affects the torque retention of the connection. Verify the serial number or application, then call (562) 693-7748.
