WASHER (Komatsu KO018489)

KO018489: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Komatsu catalog reference for this part is KO018489. This aftermarket replacement washer is a thin, flat ring used to distribute load under a fastener head. Its plain mechanical function is to provide a smooth bearing surface and prevent galling. 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.
