Abstract

A water pump for a reciprocating piston internal combustion engine is driven by a shaft located between the camshaft and crankshaft. The intermediate shaft which is driven by and coupled to the crankshaft at one wall of the crank housing. The water pump is located in a remote wall of the crank housing, which itself forms one half of the pump containment. A dish-shaped housing half screws into the remote wall to contain the pump. The intermediate shaft is connected to the pump wheel of the water pump by a hollow shaft which passes longitudinally through the crank housing. Together with the bearings, securing elements, sealing rings and a bearing flange, the shaft forms a structural unit which may be pre-assembled and easily inserted into the engine.
