Abstract: A sleeve for use in repairing a shaft having an unworn diameter and a worn diameter, the sleeve providing a fresh bearing surface for a split roller bearing, comprising: two halves which, when joined, define a cylinder having a diameter adapted to firmly engage a portion of unworn diameter shaft at each end; bolts holes adapted to releasably affix the halves together, and bolts adapted to attach the halves thereby; joiner pin holes defined in at least one intersection between the halves, the joiner holes adapted to receive joiner pins therein and adapted to serve as a stable joinder point for the halves, and joiner pins adapted to be firmly engaged therein; a smooth bearing surface defined on an external surface of the sleeve; and a split roller bearing adapted to engage the bearing surface. A method for field manufacture of said sleeve.
