ABSTRACT:
In taking dial indicator readings as a part of the so-called "reverse indicator" shaft alignment procedure for a turbine-to-compressor drive, the high breakaway torque necessary to initiate rotation of the turbine shaft is supplied by connecting such shaft to power drive means through a power chain. In this manner the turbine shaft may be quickly rotated in small, precisely controllable increments without overshoot, thus saving valuable time otherwise wasted in performing this function manually. Tapered, hollow alignment brackets minimize "bracket sag".
