Abstract: A first kit includes a manually operable hydraulic pump, a hose and a fitting for transferring the pressure in the pump to the hose. A second tool kit for bearings of relatively small size includes a fitting for coupling to the hose in the first kit and a C-shaped clamp having a pair of legs movable toward each other in accordance with increases in pump pressure. A third kit includes a receiver die and a driver die movable with the clamp legs to remove a bearing from a housing, an anvil die and a driver die for installing a bearing in a housing and a die set for swaging a prepared lip in a bearing race into a prepared chamfer in a housing. A fourth tool kit for bearings of relatively large size includes a fitting for coupling to the hose in the first kit and an in-line press having a pair of legs movable toward each other in accordance with increases in pump pressure.

Abstract: A bearing may consist of one or more components where relative motion can take place between the bearing surface and a mating surface and where the mating surface may be a component of the bearing. Many bearings are circular and may be installed and secured in a housing by swaging an annular outer lip into an annular chamfer of the housing. A tool is provided for facilitating the removal of the bearing. The tool employs one or more cutter teeth which engage the swaged lip of the bearing. Axial force applied to the cutter while it is rotated effectively cuts away the annular lip thereby allowing the bearing to be pressed out of the housing. The cutter may be used in conjunction with other tool components which include (a) a bolt which extends through the center of the circular bearing, (b) centering rings which correctly orient the bolt relative to the annular lip of the bearing, (c) a nut and (d) Belleville washers which are disposed between the nut and the cutter.
