A method of assembling an epicyclic gear train includes the steps of providing a carrier having a central axis that includes spaced apart side walls and circumferentially spaced connecting structure defining spaced apart apertures provided at an outer circumference of the carrier, gear pockets provided between the side walls and extending to the apertures, and a central opening in at least one of the side walls, inserting a plurality of intermediate gears through the central opening and moving the intermediate gears radially outwardly into the gear pockets to extend into the apertures, inserting a sun gear through the central opening after the step of inserting the plurality of intermediate gears through the central opening, moving the plurality of intermediate gears radially inwardly to engage the sun gear, and placing a ring gear on an outer periphery of the intermediate gears to engage the intermediate gears after the step of moving the plurality of intermediate gears radially inwardly.
