A stator vane is removed from an arcuate casing by placing a conforming mold over the vane airfoil with portions thereof extending axially on either side of the airfoil to provide driving surfaces, and repetitiously imparting a precisely directed impact to the driving surfaces to move the vane circumferentially within the casing. Impact to the driving surfaces is made by way of an elongated arm which is supported at its one end so as to be pivotable about the axis of the casing, and whose other end is bifurcated to straddle the vane row and impinge against the driving surfaces. In this way the individual vanes may be removed from a single stage without incurring significant damage thereto and without removing any vanes of adjacent stages. |
