A compact coupling reaming apparatus and method for reaming coupling bolt holes of a rotor coupling. The apparatus includes a fixture plate for mounting the apparatus to the face of the coupling via a plurality of the coupling bolt holes. The apparatus also includes a drill axially slidably, radially slidably, and axially rotatably mounted to the fixture plate. During the reaming process, the drill is first aligned with the center of a first coupling bolt hole, the drill having a fixed distance from an axis of the rotor after being aligned with the center of the first coupling bolt hole. After reaming the first coupling bolt hole, the drill is aligned with a center of the holes and all other coupling bolt holes to be reamed by axially rotating the drill to the center of the second coupling bolt hole while maintaining the fixed distance of the drill from the axis of the rotor.

Coupling reaming apparatus and method

The invention in its broadest form includes a device for inverting a cover with a predetermined weight from a horizontal position to an inverted position, the device comprising a crane for lifting the cover; at least two pivotable brackets each attached to both the cover and the crane and positioned to suspend a substantial amount of the weight of the cover for pivoting the cover; and a cable attached to the cover at one end and to the crane at its other end and positioned to suspend a nominal amount of the weight of the cover for supporting the cover.
