Cotter pin for American Crane 9310

The cotter pin, part number 804921, is a mechanical fastener used to secure primary hardware such as slotted nuts or clevis pins within the American Crane 9310 assembly. By preventing these primary fasteners from loosening or detaching due to operational movement, it provides necessary secondary retention for various crane systems. This component is designed with a 1/2 inch diameter to fit specific connection points throughout the machine, including boom articulation points, hydraulic cylinder mounts, and outrigger assemblies.

Installation involves inserting the pin through a pre-drilled hole in a bolt or primary pin and bending the legs to lock the assembly in place. Regular inspection of these fasteners is standard maintenance to ensure that critical connections remain secure during the operation of the crane. This part is compatible with the American Crane 9310 model.

Cotter pins are used throughout heavy machinery to provide a simple yet effective locking mechanism for pins and bolts. They act as a safety backup to ensure that primary fasteners do not back out of their positions, which helps maintain the structural integrity of the machine's various mechanical linkages and pivot points.
