ABSTRACT:
A control assembly for hydrostatic transmission having a valve controlling the flow of fluid to the pump includes a pump body member having a cavity with a moveable valve element mounted in the body and connected to a fluid pressure source, and having a neutral position. Linkage including an upstanding pin interconnects the pump to the valve element. A cover extends over the body and is secured thereto. A control shaft extends through the cover having an exterior end with a manual control lever mounted thereon, and an interior end to which a cam plate having an elongated cam slot therein is secured. A detent portion in the cam slot opposite to the upstanding pin defines a neutral position for the pin. A screw adjusts the valve element into a neutral position. A torsional spring in the cover yieldingly holds the control shaft, the control lever, the cam plate, the valve element, and the remainder of the linkage in a neutral position. The method of assembling the control assembly involves placing an elongated alignment tool on the upstanding pin and moving the tool into a prepositioned cam slot detent, placing the cover on said body and extending said tool through an aperture in the cover; securing the cover to the body, and removing the tool.
