56,077 ABSTRACT OF THE DISCLOSURE An apparatus and method are provided for aligning and supporting vane segments in the turbine section of a gas turbine. According to the invention, the vane segments are supported and aligned to an inner cylinder. The apparatus features a plate, having threaded holes, which is fixed to the inner cylinder. A threaded plug, having an eccentric hole, is threaded into each threaded hole in the plate. A pin, having flats and a chamber formed at one end, is inserted into the eccentric hole in the plug. At assembly, the plug is rotated in the threaded hole and the pin is rotated in the eccentric hole until the pin enters a slot in the inner shroud of the vane segment. The pin supports and aligns the vane segment by bearing against a side of the slot. The plug is locked in place by a nut threaded onto the plug.
