A power take off assembly (10) with a lube control system has an input shaft (12) driven by a power source, an output shaft (22), a transmission (16) for transmitting torque from the input shaft (12) to the output shaft (22), and a disconnect unit (14) for selectively coupling and uncoupling the input shaft (12) from the transmission (16). The lube control system comprises a component lube circuit (24) for lubricating a component (12) of the power take off assembly (10), a hydraulic pump (30) for supplying hydraulic fluid from a lube reservoir (34), and a lube control valve (32) for controlling communication of hydraulic fluid from the hydraulic pump (30) to the component lube circuit (24). The lube control valve (32) is operatively coupled to the disconnect unit (14) so that when the disconnect unit (14) is engaged the lube control valve (32) blocks communication from the hydraulic pump (30) to the component lube circuit (24), and when the disconnect unit (14) is disengaged the lube control valve (32) communicates the hydraulic pump (30) to the component lube circuit (24).
