ABSTRACT:
A detachable apparatus is provided which facilitates rotation and handling of an alignment dowel during its installation into a steam turbine cylinder. The apparatus consists of a body having a threaded portion and a handle. The threaded portion allows the apparatus to be attached to the dowel prior to assembly. An elongated nut is threaded onto the body of the apparatus and, after being tightened down against the dowel, locks the apparatus onto the dowel. The dowel can be rotated in the cylinder by applying torque to the handle of the apparatus or by engaging a wrench onto the elongated nut.
