Abstract: A system and method for remanufacturing a turbocharger center housing include performing a machining operation on an original center housing to remove a portion of a parent material from the original center housing. A ring having a generally rectangular cross section is attached to the center housing blank in place of the removed material to produce a rebuilt center housing. In one embodiment, the ring forms an annular surface onto which a seal is engaged to avoid external leakage of turbine exhaust gas through an interface between a turbine housing and the remanufactured center housing.
