ABSTRACT:
Tilting cab control apparatus including a horizontally extending hydraulic pump reservoir cover plate having upper and lower surfaces and edge surfaces extending between the upper and lower surfaces to define the periphery of the plate. A pump reservoir having an upper opening is sealed against the lower surface of the cover plate such that the upper and edge surfaces thereof are exposed. A pump opening of the cover plate, a pump in the opening, a valve bore communicated with the pump opening, and a control valve in the valve bore cooperate to provide pumped hydraulic fluid to a tilting cab control cylinder. One embodiment of the cover plate is specifically designed for use with single acting cylinders while a second embodiment is designed for use with double acting cylinders.
