This is a crankcase listed with fixed fittings, meaning the case comes assembled with certain hardware already installed rather than sold as a bare casting. It shows up in the crankcase section of the parts book, which puts it at the heart of the engine's bottom end, housing the crankshaft and related lower-end components.
