A tool assembly for safely rotating a heavy turbine generator rotor for alignment and maintenance purposes. The tool assembly includes a plurality of segments mounted to an outer face of a coupling affixed to an end of a shaft of the rotor, where the segments include a plurality of segment teeth extending beyond an outer edge of the coupling. A tool is positioned adjacent to the coupling and includes a support assembly, a hydraulic ram and a ratcheting pawl. The ratcheting pawl includes a drive pin positioned to engage the teeth of the segments, where extension of a piston rod from the hydraulic ram causes the coupling and shaft to rotate.

A coupling bolt hole alignment tool, a method to align two coupling holes, one in each of two coupling halves, and a system to align two coupling holes are provided. The coupling bolt hole alignment tool and system includes an expandable sleeve assembly configured to be inserted into the second coupling hole and secured into the second coupling hole with a wedge nut. A rotatable rod including an eccentric hole formed in one end of the rod is contained within the expandable sleeve assembly. A pin/paw assembly includes a pin and paw. The pin is inserted into the eccentric hole from the first coupling hole and the paw is disposed within the first coupling hole and includes a portion oriented against a wall of the first coupling hole. Rotation of the rotatable rod while the pin/paw assembly is held stationary by a restraining device aligns the two coupling holes.

A positioning arrangement (), including: an outer casing having a frame member (); a low pressure steam turbine inner casing () having an appendage () and a threaded hole through the appendage; and an alignment constraint () configured to be positioned in the threaded hole and define a positional relationship between the inner casing and the frame member. The alignment constraint includes a main body () and a discrete piggyback body (), both configured to rotate in the threaded hole as a unitary body when in a joined, end-to-end configuration.

A nut support tool for assembly and disassembly of a nut on a vertically extending bolt assembly located on a casing. The bolt assembly including a lower nut engaged on a lower end of a threaded shaft. The nut support tool includes a vertical span assembly having an upper support member located at an upper end thereof for engagement on an upper end of the bolt assembly, whereby the nut support tool is supported from the bolt assembly upper end with the vertical span structure extending parallel to the bolt assembly. An arm assembly extends from a lower end of the vertical span assembly and includes a lower guide pin for engagement with an access opening formed in a lower surface of the lower nut. The arm assembly is configured to support the lower nut, and to swivel relative to the casing.
