Cotter pin for American Crane 9310

The 804879 cotter pin serves as a secondary locking device for various assemblies within the American Crane 9310. Its primary function is to secure fasteners such as castle nuts or clevis pins, preventing them from backing out or vibrating loose during the operation of the crane. By inserting the pin through a pre-drilled hole and bending the legs, the component creates a mechanical lock that maintains the integrity of the connection.

This specific component features a 3/16 inch diameter, ensuring a precise fit within the designated hardware of the American Crane 9310. It is utilized across multiple systems of the machine, including the undercarriage and the boom assembly, where consistent retention of fasteners is required to maintain operational safety. Proper selection of the pin diameter is necessary to ensure it seats correctly in the intended hole without excessive play.

Cotter pins are used throughout heavy machinery to provide a simple, effective method of locking threaded fasteners and pivot pins in place. They act as a safeguard, ensuring that primary fasteners remain seated even under the dynamic loads and vibrations common in crane operations.
