Abstract
Looking from a front toward a rear of a vehicle, a crankcase has a cross sectional shape which gets narrower towards its bottom. The crankcase includes a crankshaft which extends parallel to a direction of travel for the vehicle. A main shaft, a counter shaft and an output shaft of a transmission are arranged in a transmission chamber on one side of the crankshaft. An oil tank is provided on the same side of the crankshaft and outwardly of the transmission chamber. The oil tank is separated from the transmission chamber by a partitioning wall. The oil tank has a substantially crescent shape, with the lower end extending beneath the output shaft. An intake port of a feed pump is provided in the lowest part of the oil tank. An oil inlet for adding oil to the oil tank is provided just above the oil tank. An overflow hole to the transmission chamber is provided in the partitioning wall. The feed pump is provided on an opposite side of the crankshaft inside the crankcase. A scavenge pump, which sucks from an oil sump at the lowest section of the crankcase and returns oil to the oil tank, is also provided on the opposite side of the is crankshaft and inside the crankcase. A drain hole communicates with the oil tank and with the transmission chamber. The drain hole is provided in a lower part of the crankcase and is closed by a drain bolt.
