1. A turbocharger assembly comprising:
a housing that comprises a through bore extending from a compressor side to a turbine side of the housing and an axial face disposed in the through bore between a through bore surface at a first diameter and a through bore surface at a second diameter;
a locating plate attached to the compressor side of the housing wherein the locating plate comprises a keyed opening; and
a journal bearing disposed in the through bore of the housing wherein the journal bearing comprises a keyed compressor end and an enlarged outer portion defined between two axial faces by an outer diameter and an axial length wherein an axial length between the keyed compressor end and a turbine end of the journal bearing exceeds the axial length of the enlarged outer portion,
wherein the axial face disposed in the through bore of the housing, the locating plate, and the two axial faces of the journal bearing axially locate the journal bearing in the through bore of the housing, and
wherein the keyed opening of the locating plate and the keyed compressor end of the journal bearing azimuthally locate the journal bearing in the through bore of the housing.
