Abstract
An internal combustion engine assembly includes a crankcase and a cam housing. The crankcase includes a crankcase cavity configured to receive a counterweight. The cam housing includes a cam housing cavity configured to receive a camshaft. A pump is positioned within the cam housing. The pump is configured to draw oil from an oil reservoir defined by the cam housing cavity. A crankshaft supports the counterweight for rotation therewith. The crankshaft is rotatably supported within the cam housing and is coupled to drive the pump. A bearing supports the crankshaft between the crankcase cavity and the cam housing cavity. The bearing includes an outer race. A seal is positioned between the pump and the bearing. The seal is positioned against the outer race to block the transmission of pressure fluctuations between the crankcase cavity and the oil reservoir.
