Claim:
A power take-off comprising: a housing; an input mechanism supported for rotation on said housing; an output mechanism supported for rotation on said housing; a clutch assembly that is operable in either a disengaged mode, wherein said input mechanism is not connected to rotatably drive said output mechanism, and an engaged mode, wherein said input mechanism is connected to rotatably drive said output mechanism; an actuating mechanism for selectively operating said clutch assembly in said engaged and disengaged modes, said actuating mechanism including a bearing assembly that is supported on said input mechanism and is axially movable to selectively operate said clutch assembly in said engaged and disengaged modes; wherein said actuating mechanism includes an actuating piston that is supported on said housing and is axial movable with said bearing assembly to selectively operate said clutch assembly in said engaged and disengaged modes; wherein said bearing assembly includes an inner race that engages said input mechanism and a plurality of bearings disposed between said inner race and said actuating piston; and wherein said actuating piston has a tapered surface, and wherein said plurality of bearings is disposed between said inner race and said tapered surface of said actuating piston.
