Abstract
A chain drive power take off assembly drives a hydraulic fluid pump from a torque converter input of a motor vehicle. The assembly includes a first, chain drive sprocket which is coupled to and driven by a engine output/torque converter input member such as an engine crankshaft or transmission input member, a chain and a second, driven chain sprocket which is coupled to a stub shaft and which, in turn, is coupled to an input shaft of the hydraulic pump. The driven sprocket resides in a housing secured to the side of the transmission and the pump is secured to the housing with its input shaft and axis of rotation disposed offset from and parallel to the axis of rotation of the transmission and torque converter input member.
