Abstract: Reduction gear units are provided comprising a gearbox, a cam assembly, a bearing assembly, a first gear and a second gear. The first and second gears may engage one another and translate rotating movement from one axis to an axis perpendicular thereto. The second gear is disengagable from the first gear by action of the cam assembly, which is adapted to disengage the second gear from the first gear through eccentric rotation of the cam assembly. In one embodiment, a bearing assembly carried by the cam assembly is preloaded. The cam assembly is disposed so that the preloaded can be maintained during manufacture of the gearbox. In another embodiment, the gearbox case and cam assembly are disposed so as to minimize internal leakage from the case and enhance sealing of the gearbox.
