Abstract
An improved camshaft and accessory drive arrangement for a V type engine wherein pairs of overhead cams are driven from the crankshaft by means of intermediate shafts that are directly driven by the crankshaft. The axis of rotation of the intermediate shafts is disposed closer to the axis of rotation of the crankshaft than the axes of rotation of the camshafts. An accessory is positioned in the valley of the V and is also driven by the crankshaft but is spaced further from the crankshaft axis of rotation than the intermediate shafts. This accessory is a water pump and an oil pump is also driven by the crankshaft at the same end of the engine.
