Gas turbine engine front center body architecture

A gas turbine engine comprising:

• a propulsor section including a propulsor;
• a geared architecture including a gearbox;
• a gas generator section including a compressor section, a combustor section and a turbine section, the compressor section having a first rotor rotationally mounted to a first spool;
• a front center body assembly defined around an engine longitudinal axis, wherein the front center body assembly defines a portion of a core flow path through the gas generator section that is forward of the first rotor relative to the engine longitudinal axis;
• a front wall mounted to the front center body assembly, wherein the front wall supports an output shaft of the gearbox that drives the propulsor;
• and
• a bearing package mounted to the front center body assembly to rotationally support the first spool, wherein the bearing package is removable from the first spool without disassembly of the first rotor;
• wherein 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.
