WASHER (Komatsu KO01641-31223)

KO01641-31223: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Komatsu catalog reference KO01641-31223 identifies this aftermarket replacement part. This washer type provides a bearing surface for a fastener head or nut. Its plain mechanical function is to distribute the load of the threaded fastener. A generic failure consequence is that a missing or crushed washer can allow the fastener to embed into the softer material, reducing preload. During routine service, a technician may find a washer that has deformed under repeated torque. Verify the serial number or application, then call (562) 693-7748.
