Cotter pin for American Crane 9310

The cotter pin, identified by part number 804910, serves as a mechanical locking component for the American Crane 9310. It is installed by inserting the pin through a hole in a bolt, clevis pin, or castle nut, after which the two legs are bent outward to lock the assembly in place. This prevents components from vibrating loose or detaching during the operation of the crane. The pin features a diameter of 3/8 inch and a length of 2-1/2 inches.

This component is compatible with the American Crane 9310 model. It is used in various assemblies throughout the machine where secure fastening of pivot points or threaded connections is required to maintain system integrity. Proper installation ensures that critical joints remain fixed under the operational loads typical of heavy machinery.

In heavy equipment, cotter pins act as a secondary safety measure to retain primary fasteners. By providing a simple mechanical lock, they prevent the rotation of nuts or the withdrawal of pins from linkages, cylinder mounts, and other articulated connections. Using the correct size ensures a proper fit within the intended hardware, maintaining the intended mechanical security of the assembly.
