Abstract
An insert and method for altering a through-hole in a body, such as a steam balance hole in a steam turbine rotor wheel. The insert has a body with oppositely-disposed first and second ends, a flange radially extending from the second end of the body, and an outer surface at a perimeter of the body between the first end and the flange. A first bore within the body defines a first opening at the first end, and the first bore and outer surface of the body cooperate to define therebetween a wall capable of being plastically deformed in a radially outward direction. A second bore within the body communicates with the first bore and has a smaller cross-section than the first bore. The installation method entails installing the insert in a through-hole and flaring the wall to clamp the axial thickness of the body between the flange and flared wall of the insert.
