A power take-off unit includes a hollow housing having an input shaft, an idler shaft, and an output shaft supported therein. The input shaft is supported on the housing and carries an input gear thereon that is adapted to be rotatably driven by an engine, transmission, or other source of rotational energy. The idler shaft is supported on the housing and carries an idler gear thereon that meshes with the input gear so as to be rotatably driven thereby. A first end of the output shaft is supported on an inwardly recessed side wall formed integrally with the housing. A second end of the output shaft is supported on a bearing cap secured about an opening formed through a second side wall of the housing. A clutch assembly may be provided for selectively connecting the idler gear to the output shaft. A mounting flange is formed integrally with the housing about the inwardly recessed side wall and is adapted to facilitate the attachment of the driven accessory directly thereto. The mounting flange may include a flat mounting surface having a pair of apertures formed therethrough. The mounting flange may further include an annular stepped recess extending formed through the inwardly recessed side wall of the housing that functions as a pilot opening to facilitate the mounting of the driven accessory on the housing of the power take-off unit and to insure that the input shaft of the driven accessory is co-axial with the output shaft of the power take-off unit. The housing of the power take-off unit significantly reduces the amount of physical space occupied by the power take- off unit and the driven accessory, and further enhances the flexibility of positioning the driven accessory relative to the power take-off unit.
