Disclosed is a compressor housing and method of assembling. The compressor housing may comprise an outer volute, a cavity, an impeller cover, a compressor diffuser and an inner volute. The outer volute includes a back wall and a curved casing. The back wall may include a receptacle and a first plurality of annular steps. The receptacle configured to receive an alignment pin. The cavity is configured to receive the compressor impeller and is at least partially defined by the back wall of the outer volute and the impeller cover. The impeller cover is configured to fragment during impact with the compressor impeller during a failure condition of the compressor impeller. The impeller cover is disposed between the inner volute and the cavity. The compressor diffuser is disposed between the back wall and the impeller cover.

Compressor housing

A turbine assembly for a turbocharger and method of assembling is disclosed. The turbine assembly may comprise a turbine wheel coupled to a rotatable turbocharger shaft, and a turbine housing that at least partially encloses the turbine wheel. The turbine housing may include an exhaust diffuser configured to direct a flow of exhaust, a support member coupled to the exhaust diffuser by a clamp assembly, the clamp assembly, a diffuser gap and a support gap. The clamp assembly may be disposed on the exhaust diffuser and on the support member. The clamp assembly includes a containment ring and a clamp plate. The containment ring may include a channel. The clamp plate may be disposed in the channel. The diffuser gap may be disposed between the containment ring and the exhaust diffuser. The support gap may be disposed between the containment ring and the support member.
