Abstract
A power takeoff having an output shaft, an output gear and a connect-disconnect clutch mechanism for connecting the output gear to the output shaft, the clutch mechanism, including a clutch hub, a disc stack slidably mounted between the output gear and the clutch hub and a piston for compressing the disc stack-thereby to bring the output shaft into rotatable engagement with the transmission of an engine; in which the clutch hub is normally biased by a spring away from the piston but is confined by snap rings to limit the hub's movement along the output shaft in such a manner so that substantially no operational force is placed on the snap rings during compression of the disc stack.
