WASHER (Komatsu KO01640-01626)

A worn washer can compromise fastener retention and lead to loosening of critical assemblies. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO01640-01626. The washer functions as a load-distributing spacer placed under a nut or bolt head. Its plain mechanical role is to prevent galling and distribute clamping force evenly across a surface. A common failure consequence is that a crushed or missing washer allows the fastener to loosen under vibration. Keeping a washer in sound condition helps maintain consistent torque on the joint. Verify the serial number or application, then call (562) 693-7748.
