Abstract
To accurately axially position and/or seal between axially facing turbine parts, a groove having a cylindrical cross-section is formed in one surface with a centerline offset toward the one surface, the groove opening through the one surface. Rod segments having corresponding cylindrical cross-sections are inserted in the groove. The rod segments have flat surfaces coextensive therewith projecting a predetermined measured distance from the one surface, thereby accurately axially locating the turbine parts relative to one another and forming a seal therebetween. The rod segments have ends abutting one another to seal the segments one to the other.
