Patent ID: 8464428

Claim:
A bearing removal and installation tool comprising: a. a force reacting member operably configured to engage a surface of a supporting flange having a surface defining a void into which the bearing is press fit; the force reacting member further comprising; i. a surrounding cylindrical sidewall having an inner diameter larger than the surface defining a void into which the bearing is press fit; ii. a back plate substantially perpendicular to and in contact with the surrounding cylindrical sidewall; iii. a surface defining a central void in the backplate; b. a reversible bearing removal member having an outermost diameter, a first longitudinal side and an opposing second longitudinal side, the bearing removal member comprising; i. on the first longitudinal side, a first bearing engagement surface configured to exert compression force upon a first bearing having an inner diameter smaller than the outermost diameter of the bearing removal member; ii. a threaded central opening from the first on longitudinal side to the opposing second longitudinal side, the threaded central opening aligned with the central void in the backplate; iii. on the first longitudinal side, a first circular sidewall having a diameter smaller than the inner diameter of the first bearing and smaller than the outermost diameter of the bearing removal member; iv. on the second longitudinal side, a second bearing engagement surface configured to exert compression force upon a second bearing having an inner diameter smaller than the inner diameter of the first bearing; v. on the second longitudinal side, a second circular sidewall having an outer diameter smaller than the inner diameter of the second bearing and smaller than the outermost diameter of the bearing removal member; vi. wherein the second circular sidewall is smaller in diameter than the first circular sidewall; c. a drive bolt configured to produce compression force between the force reacting member and the bearing removal member when operated, the drive bolt comprising; i. a threaded shaft comprising threads having the same diameter and pitch as the threaded central opening of the bearing removal member so as to interoperate therewith; ii. a non-circular, non cylindrical bolt head larger than the central void of the force reacting member; and iii. wherein the outer diameter of the shaft is smaller than the central void of the force reacting member.
