Abstract
The low pressure compressor and fan together with the intermediate case are removable as a unit from the core engine by removal of the nose cone and a stub shaft at the front of the low pressure turbine shaft and at the ID of the fan hub (50) to provide access to attachment bolts at the inner portion of the intermediate case which holds the bearing for the high pressure rotor in position within the intermediate case after assembly of the engine.
