Abstract
A positioning arrangement (142), including: an outer casing having a frame member (78); a low pressure steam turbine inner casing (140) having an appendage (60) and a threaded hole through the appendage; and an alignment constraint (10) 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 (14) and a discrete piggyback body (16), both configured to rotate in the threaded hole as a unitary body when in a joined, end-to-end configuration.
