Disclosed herein is a tool for swaging a bearing into an opening in a bearing housing, which apparatus is operable in confined spaces, such as in an aircraft application. The tool has a threaded elongated member or bolt that extends through the bore of the bearing. The tool also has a roller fixture assembly adapted to be positioned on one side of the bearing and positioned on one end of the elongated member. The roller fixture assembly has a number of rollers and a roller fixture shell that supports the rollers for engagement with the bearing to swage the bearing against the bearing housing. The bearing swaging tool also has a locating fixture assembly adapted to be positioned on the opposite side of the bearing from the roller fixture assembly. The locating fixture assembly is supported on the other end of the elongated member and includes a locating fixture with a first side adapted to be positioned against the bearing and bearing housing. The locating fixture assembly includes means for selectively controlling the amount of axial movement of the locating fixture with respect to the elongated member in response to rotation of the elongated member with respect to the bearing.
