An oil cooled and fluid pressure operated clutch assembly is described for use in a vehicle drive line. The clutch assembly is characterized by: an encapsulating clutch housing, capable of containing oil, one end of the housing being secured to a rotatable component of a vehicle drive line for rotation therewith and an opposite end of the housing being provided with an aperture having an annular periphery; an output shaft extending through the aperture; a non-rotatable support member having an annular portion extending through the aperture and being disposed about the output shaft; sealing means operable to provide an oil seal between the periphery of the output shaft and the periphery of the aperture; at least one axially movable clutch disk disposed within the clutch housing and connected with the output shaft for rotation therewith; first fluid means including a piston chamber within the clutch housing, a piston within the piston chamber and axially movable between engaged and disengaged positions, the piston when in its engaged position causing the clutch disks to be held for rotation with the clutch housing, and first conduit means extending to the piston chamber through which fluid under pressure may be introduced to cause the piston to move to its engaged position; second fluid means capable of introducing cooling oil into the clutch housing to be used for cooling the clutch disks, the second fluid means including second conduit means; and scavenger means capable of scavenging the oil used for cooling the clutch disks and causing it to be removed from the clutch housing.
