1. A method for installing a rotor on a shaft of a gas turbine engine, or removing the rotor from the gas turbine engine, the method comprising:
attaching a stabilizer to a flange of the shaft of the gas turbine engine; movably engaging a rotor holder with the stabilizer to permit movement of the rotor holder relative to the stabilizer along a rotation axis of the shaft and substantially prevent movement of the rotor holder relative to the stabilizer transverse to the rotation axis of the shaft; with the rotor attached to the rotor holder, the rotor released from the shaft and the rotor holder engaged with the stabilizer, moving the rotor holder and the rotor together along the rotation axis of the shaft toward or away from an installed position of the rotor along the shaft; and after moving the holder and the rotor along the rotation axis of the shaft, either:
attaching the rotor to the shaft when the rotor holder and the rotor have been moved toward the installed position of the rotor; or
removing the rotor from the gas turbine engine when the rotor holder and the rotor have been moved away from the installed position of the rotor.
