A lifting tool for lifting a rotor associated with a generator so as to allow a rotor bearing to be removed from a bearing pedestal beneath the rotor. The tool includes a semi-circular base portion that is bolted to the bearing pedestal and a pair of jack screws mounted to the base portion. A hydraulic ram is mounted to the base portion between the jack screws and is positioned against the rotor when the tool is bolted to the bearing pedestal. The ram is used to lift the rotor away from the bearing and the jack screws are used to hold the rotor up once it is in the desired location, where the ram is then lowered.
