Abstract: A turbocharger includes a shaft extending between a first shaft end coupled to a turbine wheel, and a second shaft end coupled to a compressor wheel. The turbocharger also includes a bearing housing assembly including a bearing housing presenting an interior surface having a first diameter. The interior surface defines a bearing housing interior. A bushing is disposed in the bearing housing interior, extends between first and second bushing ends, is coupled to the shaft, and includes a first anti-rotation component. A retention shoulder extends away from the interior surface and radially inward proximate to one of the first and second bushing ends, and presents an inner surface having a second diameter less than the first diameter to limit axial movement of the bushing. The retention shoulder includes a second anti-rotation component engagable with the first anti-rotation component to limit rotational movement between the bushing and the bearing housing.
