Abstract
A method is presented for aligning internal turbine components, such as a packing ring holder, a rotor during assembly of the turbine. The method includes the step of inserting a plurality of proximity probes into a gap between the rotor and the packing ring holder. Thereafter, the packing ring holder is adjusted until the readouts from all probes are the same. In order to practice the method, a tool has been devised for inserting the proximity probes into the gap. The tool comprises a semi-rigid metal strip upon which the probes are spaced and mounted and further includes means for biasing the probe away from the rotor surface.
