    Abstract: A gas turbine engine has a fan and a turbine section including a turbine rotor to drive the fan through a gear reduction module. An input shaft downstream of the turbine rotor includes a flexible mount driving the gear reduction. The input shaft is mounted within a bearing module. The gear reduction module has static structure mounted to an engine housing through a flexible mount. Oil is supplied into the gear reduction. An oil tube supplies oil from the gear reduction to the bearing module, and is received within openings in the static structure, and a housing for the bearing module. The oil tube extends through an assembly guide having a guide opening spaced away from an outer periphery of the oil tube. The guide opening is intermediate the openings. A method is also disclosed.

    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 fluid delivery manifold provides a journal fluid path and a gear mesh fluid path that is separate from the journal fluid path. An example turbomachine lubrication system includes a geared architecture having a journal bearing and a gear. In this example, a manifold provides a portion of a first fluid path and a portion of a second fluid path separate from the first fluid path. The first fluid path is operative to communicate a first fluid from a fluid supply to the journal bearing. The second fluid path is operative to communicate a second fluid from the fluid supply to a gear mesh.
