Abstract
Abstract An apparatus for use as an alignment and centering tool for providing a fixed spatial alignment between a rotor and a stator, including a base member and at least one finger member fixedly secured to the base member and extending generally therefrom. The finger member is adapted to be positioned between the rotor and the stator that are to be aligned and centered. A first releasable coupling is provided for operatively connecting the rotor and the finger member to hold the tool and the rotor in a selectively releasable, fixed spatial relationship. A second releasable coupling is also provided for operatively connecting the stator and the finger member to hold the tool and the stator in a selectively releasable, fixed spatial relationship. An alternative user-adjustable embodiment is also provided.
