A lubrication system (300) for a transfer case (200) includes a shaft (302) having a lubricant inlet port (306) and a hollow bore (304) for transporting lubricant within the shaft (302), a pump (310) having a pump housing (312) and one or more pumping elements (318) that are disposed in the pump housing (312), and a clutch assembly (330). The clutch assembly 330 has an engaged position in which rotational force from the shaft (302) is transferred to the one or more pumping elements (318) to cause operation of the pump (310), and a disengaged position in which rotational force from the shaft (302) is not transferred to the one or more pumping elements (318). An actuator (370, 410) is operable to cause the clutch assembly (330) to move between the engaged position and the disengaged position.
