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. A fifth kit includes a receiver die, a pull-rod shaft and a driver die movable with the legs in the press to remove a bearing from, or install a bearing in, a housing. Dies in the fifth kit operate with the pull-rod shaft to swage a prepared lip in a bearing race into a prepared chamfer in a housing. Systems including the different kits may also be proof tested to proper operation.
