Abstract: An improved quick disconnect mechanism between a rotatable end yoke hub of a power take-off and a journal shaft is disclosed. The hub has a central longitudinal passageway formed therethrough which is co-axial with the axis of rotation. An aperture is formed completely through the hub in a direction which is generally perpendicular to the longitudinal axis of the hub. The aperture extends at least partially through the passageway formed in the hub. One end of the aperture is formed with a reduced diameter portion, while an end plug is inserted through the other end of the aperture so as to close it. The end plug includes a body portion sized to fit within the aperture and a head portion sized larger than the aperture. Prior to installing the end plug, a locking pin is slidably disposed in the aperture. The portion of the slidable locking pin which extends outwardly from the hub is inclined (relative to the radii of the hub and journal shaft) in a direction away from the direction of rotation of the hub.
