Abstract

A combined power take-off and hydraulic pump assembly includes a power-take off including a housing portion having an opened end, an input put mechanism that is adapted to be connected to a source of rotational energy, and an output mechanism that is rotatably driven by the input mechanism. The assembly also includes a hydraulic pump including a housing portion having an opened end, a fluid inlet port that is adapted to communicate with a reservoir containing a quantity of relatively low pressure hydraulic fluid, and a pumping mechanism that is rotatably driven by the output mechanism of the power take-off. An intermediate housing has a first opened end that cooperates with the opened end of the housing portion of the power take-off and a second opened end that cooperates with the opened end of the housing portion of the hydraulic pump. The intermediate housing also has a fluid outlet port that communicates with the pumping mechanism and that is adapted to communicate with a hydraulically driven device. The intermediate housing may also support a bearing that, in turn, supports a portion of the output mechanism of the power take-off.
