WASHER (Komatsu KO01602-21338)

KO01602-21338: A worn washer can compromise the clamping force of a bolted joint, leading to loosening over time. The Komatsu catalog reference KO01602-21338 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 across a wider area. A common failure consequence is that a crushed or missing washer allows the fastener to embed into the softer material, reducing preload. During routine disassembly, technicians often find washers that have deformed or corroded. Verify the serial number or application, then call (562) 693-7748.
