A process for remanufacturing valve bodies, such as fuel injector valve bodies, includes regrinding a valve seat of a salvaged valve body with a grinding apparatus, and linking a center axis of the valve seat with a center axis of a guide bore for a valve which contacts the valve seat. Linking the center axis of the valve seat with the center axis of the bore includes contacting a locating element of the grinding apparatus with a locating surface on an outer diameter of the valve body during regrinding the valve seat. Locating on the outer diameter enables run-out between the axes to be inhibited during regrinding the valve seat based on concentric congruity between the locating surface and the bore. |
