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.

A method of aligning a turbine rotor within a turbine casing relative to an annular surface comprising the steps of: mounting the rotor in the lower casing half whereby a radial gap is defined between the rotor and the annular surface around a portion of the rotor circumference; calibrating a plurality of test probes in order to obtain a common datum; inserting said calibrated test probes into the radial gap around the circumference of the rotor for measuring the radial distance from each test probe to the rotor surface; and, adjusting the position of the annular surface so that the radial distances between each test probe and the rotor surface are the same.
