WASHER (Komatsu KO6732-31-4120)

KO6732-31-4120: 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 cross-references part number KO6732-31-4120. The washer distributes the load of a threaded fastener across a wider surface area. A plain mechanical function is to prevent galling between the fastener head and the mating surface. A concrete generic failure consequence is that a missing or deformed washer may allow the fastener to embed into the softer material, reducing preload. During routine service, a washer that is crushed or split should be replaced to maintain joint integrity. Verify the serial number or application, then call (562) 693-7748.
