Abstract
A lubrication system () for a transfer case () includes a pump () selectively supplying a working fluid to a fluid reservoir of an actuator () configured to apply force to a clutch assembly () to cause the clutch assembly () to move between a disengaged position and an engaged position. The lubrication system also includes a relief valve () having a relief valve inlet fluidly coupled to the fluid reservoir of the actuator () which opens to receive the working fluid based on a threshold pressure level of the working fluid in the fluid reservoir. The lubrication system also includes a trough () fluidly coupled to a relief valve outlet of the relief valve (). The trough () carries the working fluid from the relief valve outlet to a bearing assembly () associated with at least one of an input shaft () and a primary output shaft () of the transfer case () when the clutch assembly () is in the disengaged position.
