Abstract
An axle pivot boring tool is disclosed. Such tool comprises a plate having an enlarged circular aperture in a central extent thereof. A plurality of small apertures are symmetrically located therearound. A plurality of peripheral holes for mounting the plate on the upper extent of a tractor are provided. A cylindrical nut with an enlarged head and a cylindrical section is positionable in the large aperture for alignment purposes. A housing with a central bore and a radial flange is adapted to be bolted to the interior surface of the plate through the small apertures with bolts and nuts coupled therebetween. The central bore is adapted to receive the cylindrical section of the nut with a bearing sleeve therebetween. A primary shaft is positionable through the nut with an external end adapted to be coupled to a half-inch drill and an internal end with an axial recess and radial set screws. The lower end of the shaft also has a removable cutting element extending radially outward therefrom and is held in place by one of the set screws. A secondary shaft is positionable in the recess and held in place by another of the set screws.
