Expansion plug for American Crane 9310

The expansion plug, part number 810461, serves as a sealing component for the American Crane 9310. It is designed to fit into openings created during the casting or machining process of engine blocks, cylinder heads, or various machinery housings. By creating a secure seal, this component helps contain internal fluids such as engine oil or coolant, preventing leaks and protecting the internal systems from external contaminants.

This component is compatible with the American Crane 9310 crawler crane. In heavy machinery, expansion plugs are installed into cored holes to block passages that are no longer required after the manufacturing process. They ensure the integrity of pressurized or fluid-filled systems by maintaining a tight fit within the bore. In some specific applications, these plugs may also serve as a pressure relief point, designed to yield if internal pressures exceed safe operating limits to protect more complex or costly engine components from catastrophic failure.
