Abstract: Apparatus is provided for longitudinally inserting a rotor having a shaft into a stator having an opening adapted to receive the rotor. The apparatus includes a stationary support having an elongated cantilevered beam extending horizontally outwardly therefrom, and a pedestal support spaced horizontally from the stationary support. Cradles are provided on the pedestal support and on the distal end of the beam to support the ends of the rotor shaft. A carriage is mounted for movement between the supports in a direction parallel to the longitudinal axis of the beam, and is adapted to support the stator. The carriage has means for selectively adjusting the position of the stator relative to to the supported rotor in multiple directions. The carriage is moved away from the stationary support to cause the stator to envelop the rotor.
