Abstract
In an engine with a torque converter for a saddle seat or buggy-type vehicle, a crankshaft and a shift drum placed approximately in parallel to a longitudinal direction of a vehicle are rotatably supported by a crankcase. The torque converter is provided on one end of an extension section of the crankshaft at an outer section of the crankcase. A double rotor type oil pump and a water pump are installed on the engine without enlarging a width of the engine. The lengths of piping to an oil cooler or radiator arranged in a front section of a vehicle body is made shortest. A part of the oil pump is overlapped with the shift drum and the torque converter, when viewed from the front of the engine. The oil pump is driven by chains from the crankshaft and is arranged in a space between an outer surface of the crankcase and the torque converter in a longitudinal direction. The water pump is coaxially connected to the oil pump and is provided on a side far from the torque converter when viewed from the center of the engine.
