Abstract
A gas turbine engine includes a propulsor, a geared architecture including a gearbox, a gas generator section including a compressor section having a first rotor rotationally mounted to a first spool. A front center body assembly defines a portion of a core flow path that is forward of the first rotor relative to an engine longitudinal axis. A front wall is mounted to the front center body assembly, which supports an output shaft of the gearbox that drives the propulsor. A bearing package is mounted to the front center body assembly to rotationally support the first spool. The bearing package is removable from the first spool without disassembly of the first rotor. The bearing package supports the first spool during at least one of a first period prior to installation of the geared architecture into the engine and a second period after removal of the geared architecture from the engine.
