CRANKCASE COVER WITH OIL PASSAGES

摘要

A cover (290) for a crankcase (110) of an internal combustion engine (100) is disclosed. The cover (290) has an inside surface (500) in which walls (510) are formed extending from the inside surface (500) to form channels (520). A plate (530) covers the channels (520) to form passages that allow the flow of oil from various inlets (540, 560) to various outlets (280, 550) in the passages, but does not necessarily completely seal the channels. The plate (530) is secured to the inside surface (500) of the cover by threaded members (580) that are inserted through fastening apertures (590) in the plate (530) and are threaded into corresponding internally threaded apertures (600) in the inside surface (500) of the cover (290).
