Abstract: A method of assembling an aircraft gearbox. The method includes mounting an outer race and a plurality of rollers of a roller bearing in an opening of a gearbox housing, mating a cylindrical guide sleeve having a lead-in chamfer with a gear assembly having a gear and a cylindrical shaft such that a trailing shoulder of the guide sleeve is positioned proximate a leading shoulder of the shaft, the shaft including an inner race of the roller bearing, axially passing the lead-in chamfer of the guide sleeve through the plurality of rollers, radially outwardly urging the rollers toward the outer race with the guide sleeve, axially passing the leading shoulder of the shaft through the plurality of rollers, positioning the inner race relative to the plurality of rollers to form the roller bearing and removing the guide sleeve from the gear assembly.
