Abstract
A method of re-manufacturing a shaft-hub assembly to be used in a transfer case, the method including the steps of: determining an initial diameter of a journal bearing of a main shaft that has been used in the transfer case; comparing the determined initial diameter to a predetermined minimum threshold, and discarding the main shaft if the determined initial diameter is below the predetermined minimum threshold; if the determined initial diameter is above the predetermined minimum threshold, preparing the bearing surface of the journal bearing for a thermal spray process; thermally spraying an aluminum bronze material onto the bearing surface; and machining the aluminum bronze material to achieve an outside diameter that provides a desired running clearance with a corresponding finished inside diameter of a central bore for a hub to which the main shaft will be assembled in the transfer case.
