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.

Abstract: A turbocharger includes a two-piece thrust collar that includes inner and outer portions disposed around a rotatable shaft. The inner portion is engaged with a bushing disposed in and connected to the center housing by a retainer. The outer portion is disposed adjacent the inner portion along the rotatable shaft and connected to the rotatable shaft such that it rotates therewith. The outer portion forms an annular channel that extends in a radial direction relative to the rotatable shaft and peripherally around the shaft. An oil deflector is connected to the compressor back-plate and includes a base flange and a raised portion disposed at least partially over the annular channel.
