Cotter pin for American Crane 9310

The 804899 cotter pin is a mechanical fastener used in the American Crane 9310. This component is designed with a 5/16 inch diameter to fit through pre-drilled holes in shafts, bolts, or other hardware. Once inserted, the ends of the pin are bent to create a mechanical lock that prevents the associated fastener from backing off due to operational loads or movement. By maintaining the position of these connections, the pin helps preserve the structural integrity of the assembly.

This component is specifically sized for the 9310 model to ensure a correct fit within its intended mounting points. Proper sizing is necessary to maintain the retention of critical joints throughout the crane. Using the correct diameter ensures that the pin remains seated securely within the hole, providing the intended level of mechanical restraint for the assembly.

In heavy machinery, cotter pins serve as a standard method for securing clevis pins, castle nuts, and other hardware that must remain fixed but may require periodic removal for maintenance. They provide a simple, effective way to lock threaded or pinned connections, ensuring that components remain in their designated positions during the operation of the crane.
