    Abstract: A system for maintaining a position of a bearing compartment in a gas turbine during disassembly of a low-pressure turbine of the gas turbine engine includes a forward annular shaft defining an engine centerline axis. The system includes a ring radially inward from and engaged with an inner diameter surface of the forward annular shaft. An aft annular shaft is radially inward from the forward annular shaft and aft of the ring. The ring is connected to a forward end of the aft annular shaft for common rotation therewith. The ring retains the aft annular shaft during disassembly. The system includes a stack nut axially held between an aft facing shoulder of the forward annular stub shaft and a forward facing surface of the ring to retain the stack nut during disassembly.

    Abstract: A trim balance device for a gas turbine engine having a rotatable shaft extending along a central longitudinal axis of the gas turbine engine includes a trim balance nut that is at least partially disposed about the rotatable shaft. The trim balance nut defines an aperture that extends from a first trim balance nut end towards a second trim balance nut end along the central longitudinal axis. The aperture being arranged to receive and seat a balance weight.
