Abstract: A bearing cup installing tool adjustable for installation of bearings of various diameters. The tool has a cross head with a driving handle connected thereto and extending from one side thereof. An adjusting screw associated with the cross head extends outwardly therefrom from a side opposite the driving handle and three jaws are pivotally mounted on the cross head in equally-spaced relation and extending from the same side of the cross head as the adjusting screw and disposed in a circular array with the adjusting screw at the center. Each jaw has a bearing cup engaging notch at a free end thereof. The adjusting screw can be moved lengthwise of the cross head, by coacting structure on the adjusting screw and the jaws, to pivot the jaws to set an effective diameter as defined by the bearing cup engaging notches for engagement with a bearing cup.
