1. A method of disassembling a rotor module from a gas turbine engine, the gas turbine engine comprising a rotor output shaft, a centre-bolt, and the rotor module, the rotor module comprising, a sleeve, at least one rotor stage, at least one stator stage, a casing and an axis, the method comprising:
attaching a fixture to the at least one rotor stage,
attaching the fixture to the casing,
detaching the centre-bolt from the at least one rotor stage,
detaching the sleeve from the rotor output shaft,
attaching the fixture to the sleeve,
removing the rotor module and the fixture from the rotor output shaft, and
translating the sleeve in an axial direction relative to the at least one rotor stage.
