ABSTRACT:
A coupling device (11) including a housing (13, 15) defining a clutch cavity (39) and at least one window (55, 57) extending through the housing adjacent the clutch cavity. A clutch assembly (29) is disposed within the clutch cavity and includes a first clutch disc (31) having ears (63) to limit rotation relative to the housing. The housing defines a plurality of fluid passages (67) extending axially from the window to the clutch cavity, the housing defining a plurality of axial recesses (61), each of which receives one of the ears of each disc. Each of the fluid passages (67) is in fluid communication with one of the axial recesses (61), and receives fluid as the window passes through a reservoir of fluid (F).
