WASHER (Komatsu KO01643-01645)

KO01643-01645: 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 and carries the cross-reference number KO01643-01645. The washer functions as a load-distributing spacer placed under a fastener head or nut. Its plain mechanical role is to prevent galling between the fastener and the mating surface. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the surface, reducing preload. During a routine fastener inspection, a deformed washer may indicate overtightening or surface fatigue. Verify the serial number or application, then call (562) 693-7748.
