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 seal assembly may include a housing that supports a seal ring, which may be made of carbon. A radial restrictor of the assembly prevents undesired movement of any portion of the ring during assembly, and has an axially projecting protuberance rigidly engaged to one of the housing and the carbon seal ring, and a cavity defined by the other of the housing and the carbon seal ring for receipt of the protuberance. A clearance directly adjacent to and radially outward from the protuberance and within the cavity generally allows for wear of the ring and is equal to or greater than a pre-determined radial wear distance of the carbon ring seal.
