Claim:
A system for mounting a bearing assembly on a shaft, comprising: an internal flange axially secured to the bearing assembly; an external flange secured to the internal flange via a plurality of fasteners, the external flange having recesses in which drive threads are formed; a sleeve having a tapered outside diameter, the sleeve being configured to be driven between the bearing assembly and the shaft; a plurality of screws configured to engage the drive threads of the external flange to drive the sleeve to an initial position between the bearing assembly and the shaft; and a removable spacer disposed between the external flange and the internal flange and having a width that defines a distance between the initial position of the sleeve with respect to a final position of the sleeve; wherein the distance between the initial position and the final position is equal to the amount of axial sleeve movement required to properly mount the bearing assembly to the shaft; and wherein the sleeve includes a plurality of recesses configured to align with the drive threads in the external flange, the sleeve recesses forming front load surfaces contacted by the screws to drive the sleeve to the initial position.
