ABSTRACT:
A water pump used in a cooling system for an internal combustion engine includes a pump shaft fixedly connected to an impeller means and detachably connected to a driven gear. The driven gear is in meshing engagement with a drive gear which is detachably mounted on a cam shaft rotated by the engine. The two shafts are not axially aligned, but are arranged in parallel relationship with each other. Thus, the optimum rotational ratio between the shafts may be obtained by adjusting the radii of the gears.
