Abstract:
An engine assembly includes an air-cooled engine and an external oil reservoir. The engine includes a vertically-oriented crankshaft a crankcase cover having a front portion and a rear portion, wherein the front portion of the crankcase cover and the cylinder head are located forward of a vertical plane that includes the crankshaft axis, a return pump housing formed in the exterior of the crankcase cover, a return pump positioned in the return pump housing, and a return pump inlet formed through the crankcase cover, wherein the return pump inlet is located in the front portion of the crankcase cover and the return pump inlet is located closer to the camshaft than to the crankshaft. The external oil reservoir includes an oil tank and an oil filter assembly.

Claim (Index 11):
An engine assembly, comprising:\n an air-cooled engine, comprising:\n a vertically-oriented crankshaft configured to rotate about a crankshaft axis; \n an engine block including a cylinder; \n a cylinder head coupled to the cylinder; \n an oil passageway configured to distribute oil; \n a crankcase cover having a front portion and a rear portion, wherein the front portion of the crankcase cover and the cylinder head are located forward of a first vertical plane that includes the crankshaft axis; \n a crankcase chamber defined by the engine block and the crankcase cover; \n a supply pump in fluid communication with the oil passageway; and \n a return pump including a return pump inlet in fluid communication with the crankcase chamber, wherein the return pump inlet is located in the front portion of the crankcase cover and the return pump inlet is located closer to the camshaft than to the crankshaft, and wherein the first vertical plane is perpendicular to a second vertical plane including the crankshaft axis and an axis of rotation of the return pump; \n an external oil reservoir, comprising:\n an oil tank defining an oil chamber; \n wherein the crankcase chamber and the oil chamber are sized to provide at least five hundred hours of engine oil life.
