Round washer for American Crane 9310

The round washer, identified by part number 407649, is a fastening component used in the assembly and maintenance of the American Crane 9310. It functions by distributing the load of a threaded fastener, such as a bolt or nut, over a larger surface area of the material being joined. This distribution helps prevent surface damage and assists in maintaining a stable connection between machine components.

This component is compatible with the American Crane 9310. In heavy machinery of this type, washers are utilized at various connection points, including structural assemblies, engine mounts, and cab mounting systems. Proper installation of the correct washer is necessary to ensure the integrity of the bolted joints throughout the crane.

Washers generally act as load-bearing surfaces under the head of a bolt or a nut. By increasing the contact area, they reduce the pressure exerted on the material surface and help prevent the fastener from loosening during operation. They may also function as spacers or shims to achieve the required fitment within a mechanical assembly.
