Abstract
A method of servicing an aircraft engine mounted to an aircraft, the aircraft engine having a central axis and a case assembly including a first case secured to a second case and being axially offset from one another, the method includes: while the aircraft engine remains mounted to the aircraft: radially supporting, relative to the central axis, an end of a shaft of the aircraft engine through a central passage extending axially through the first case; creating a gap between the first case and the second case by axially moving the first case away from the second case and relative to the shaft while preventing axial and radial movements of the shaft relative to the central axis; radially and axially supporting the shaft at the gap; and removing the first case by disconnecting the end of the shaft while maintaining the shaft radially and axially supported at the gap.
