Abstract
During a disassembly method, a nut is unthreaded from a tie shaft. Prior to the unthreading of the nut, the tie shaft is threaded into a first rotating structure, a second rotating structure is mounted to the first rotating structure by a first tight fit connection, a third rotating structure is mounted to the second rotating structure by a second tight fit connection, and the second rotating structure and the third rotating structure are axially stacked and secured between the first rotating structure and the nut. The tie shaft is unthreaded from the first rotating structure. The tie shaft is axially translated to abut a shoulder of the tie shaft against an axial distal end of the second rotating structure. The tie shaft is further axially translated to disconnect the second rotating structure from the first rotating structure at the first tight fit connection and pull the second rotating structure away from the first rotating structure while the third rotating structure remains mounted to the second rotating structure by the second tight fit connection.
