Abstract
A modular porting manifold for a hydrostatic transmission that serves as an end cover for the hydraulic motor, and which may be modularly interfaced with multiple different pump configurations having the same or similar pump interface across the different pump configurations. A pump interfacing section of the porting manifold may have a mating surface that interfaces with a corresponding mating surface of an outwardly addressable manifold of the pump. The pump interfacing section of the porting manifold may have at least two ports for communication of hydraulic fluid with the pump, in which the at least two ports are laterally spaced apart in the same horizontal plane to align with at least two corresponding ports on the pump manifold that are also in the same horizontal plane, which may provide less complex and easier to manufacture flow passages for the porting manifold and/or pump end block.
