Abstract: A lubricant manifold for gear system of a turbofan engine includes a base plate defining an inlet, an outlet and a plurality of open channels. The open channels define a portion of a corresponding plurality of lubricant passages. A cover plate is attached to the base plate to complete the formation of the plurality of lubricant passages. An interlocking interface between the base plate and the cover plate secures the cover plate to the base plate.

Abstract: A method for assembling a turbofan engine (20) comprises coupling a bearing assembly (176) and a shaft (420) as a unit to a bearing support (453). A transmission (46) and the fan shaft (132) are installed to a front frame assembly (172). The bearing assembly and shaft are installed as a unit so that the shaft engages a central gear (52) of the transmission and the bearing support engages the front frame assembly.

Abstract: An example turbomachine geared architecture support assembly includes a compliant member configured to hold a geared architecture within a turbomachine. The compliant member has a compliant section that permits rotation of the geared architecture relative to a fixed portion of the turbomachine. A stop limits rotation of the geared architecture relative to the fixed portion of the turbomachine.
