Cotter pin for American Crane 9310

The 804896 cotter pin serves as a mechanical locking device within the American Crane 9310. It is installed through a hole in a primary pin or bolt, after which its split ends are bent to prevent the fastener from backing out or dislodging during machine operation. This component is commonly found in various pivot points, linkage assemblies, and structural connections throughout the crane, including the boom system, chassis, and lifting mechanisms.

This specific part features a diameter of 1/4 inch and a length of 4 inches. It is compatible with the American Crane 9310 model. Proper installation involves ensuring the pin fits securely within the designated hole of the primary fastener before the legs are spread to lock the assembly in position.

Cotter pins are used throughout heavy machinery to provide a simple yet effective method of retaining pins and clevises. By preventing the axial movement of primary fasteners, they maintain the integrity of articulated joints and linkages, ensuring that critical components remain connected during the dynamic loads experienced by cranes.
