ABSTRACT:
A power compounder, for transmitting rotary power from a transmission to a driveline assembly includes a housing adapted to be mounted to the transmission. An input shaft is rotatably supported by the housing and adapted to be driven by the transmission. The compounder further includes an output shaft adapted to drive the driveline assembly and a gearset. The gearset selectively communicates rotational movement between the input and output shafts. A centralized passageway is formed in the input shaft. A separator insert is disposed in the passageway and is adapted to carry fluid at a first pressure to a first predetermined location and carry fluid at a second pressure to a second predetermined location.
