Abstract
A power unit, including an engine and a transmission, is transversely arranged in a vehicle with a crankshaft arranged parallel to a traveling direction of the vehicle. Looking at a crankcase from the front, a camshaft is arranged to one side of the crankshaft. A balancer shaft is also located on the one side of the crankshaft and coaxailly drives an oil pump. The transmission and an oil tank are arranged on the opposite side of the crankshaft. The crankshaft includes a crank sprocket which drives the cam shaft via a cam chain and a cam sprocket provided on one end of the cam shaft. The cam sprocket and the oil pump are arranged on either side of a balancer attached to the balancer shaft. The power unit arrangement allows for an increase in the potential capacity of the oil pump of a dry sump type lubrication system without causing an increase in the size of a crankcase.
