Claim:
1. A method of remanufacturing a machine component having a plurality of holes, wherein the holes are to be matched with corresponding holes of an adjacent component in a machine assembly for co-axially receiving fasteners therein, the method of remanufacturing comprising: selecting a first set of holes from the plurality of holes on the machine component that lie within a first limit of positional tolerance with respect to a first portion of the corresponding holes of the adjacent component; boring each hole from the first set of holes to a first enlarged diameter to define openings in axial alignment with the first portion of the corresponding holes of the adjacent component; selecting a second set of holes from the plurality of holes on the machine component that lie outside the first limit of positional tolerance with respect to a second portion of the corresponding holes of the adjacent component; boring each hole from the second set of holes to a second enlarged diameter; plugging each of the bored second set of holes with a deformable insert; and drilling the inserts to define openings in axial alignment with the second portion of the corresponding holes of the adjacent component.
