Abstract
A method of repairing a housing for a machine system includes returning an inner diameter of at least one bearing bore of the housing to a uniform diameter state. The at least one bearing bore is prepared for resurfacing via removing deeply entrapped grease from within pores in cast surface material of the housing subsequent to returning the inner diameter to a uniform diameter state. Subsequent to preparing the at least one bearing bore for resurfacing, it is resurfaced with a material different from cast material of the housing and bonded therewith, for example via thermal spray coating. Resurfacing a cast metallic component, of iron, steel, or the like with metal spray coating may include removing deeply embedded grease from pores of cast surface material of a cast component, in preparation for spraying the cast component with metal spray resurfacing material.
