Tool for turbine rotor thrust clearance test

A tool for thrust testing a first rotor configured to couple to a second rotor, the tool comprising:

• at least one first rotor thrust engagement element, each first rotor thrust engagement element including:
• an adjustable clamp including a first engagement member, a second engagement member, and a space adjuster configured to adjust a distance between the first engagement member and the second engagement member, wherein the first and second engagement members are configured to engage opposing axial ends of at least one coupling flange of a load coupling extending from at least the first rotor, and wherein the adjustable clamp extends around a radially outer facing surface of the at least one coupling flange of the load coupling;
• a dual-action linear actuator coupled to the adjustable clamp and having an actuator end;
• and
• a fixture configured to axially fix the actuator end of the dual-action linear actuator to a stationary structure adjacent the first rotor;
• and
• a controller configured to activate the dual-action linear actuator of each first rotor thrust engagement element to move the first rotor between a first axial direction and a second, opposite axial direction to the first axial direction.
