What is a CHRA?
A complete turbocharger is essentially a Centre Housing Rotating Assembly (CHRA or core assembly) with housings fitted to
each side. The turbine housing directs exhaust gas to power the turbine wheel, the compressor housing directs air into the
engine. The turbine housing will have a wastegate to control the turbine speed, or as is more common on diesel engines, there
is a variable vane mechanism giving much better control of the turbo, reducing lag, and improving performance.
The wastegate or vane mechanism is controlled by an actuator – which could be controlled either electronically or by a vacuum
system. The CHRA is a rotor (turbine wheel on one side, compressor wheel on the other) that is held in a bearing system
allowing it to rotate at high speed on a pressurized oil film similar to the engine. Turbo remanufacturer’s traditionally stripped
the complete turbocharger and CHRA, examine all the individual components, replacing these where necessary, and install
brand new bearings and seals.
