1. A method for disassembling a rotor of a gas turbine engine, comprising:
providing the rotor that includes a rotor disk and a plurality of rotor blades arranged circumferentially about an axis, the plurality of rotor blades including a plurality of airfoils and a plurality of attachments that mount the plurality of rotor blades to the rotor disk, and each of the plurality of rotor blades including a respective one of the plurality of airfoils and a respective one of the plurality of attachments;
arranging a press against the rotor, the press axially engaging each of the plurality of rotor blades; and
moving the press axially along the axis to simultaneously push the plurality of rotor blades and remove the plurality of attachments from a plurality of slots in the rotor disk
wherein the press includes a sleeve and an actuator;
wherein the sleeve extends circumferentially around the axis, and the sleeve simultaneously axially engages each of the plurality of rotor blades; and
wherein the moving of the press axially along the axis comprises pushing the sleeve using the actuator to simultaneously push the plurality of rotor blades with the sleeve and remove the plurality of attachments from the plurality of slots in the rotor disk.
