Abstract
A transmission for a pump is constructed of an input member rotatably mounted in a housing and including a splined shaft portion and an input flange portion, an output member rotatably mounted in the housing in axial alignment with the input member and including a splined shaft portion and an output flange portion, and a sliding gear slidably mounted on the splined shaft portion of the input member at an internal splined portion thereof and having externally facing gear teeth. The sliding gear is movable between a "ROAD" position wherein its internal splined portion engages both the splined shaft portions of the input member and the output member and a "PUMP" position wherein its internal splined portion only engages the splined shaft portion of the input member and the gear teeth thereof are in engagement with gear means for driving the pump shaft.
