Abstract: A turbocharger includes a turbine housing defining a turbine chamber and a compressor housing defining a compressor chamber. A turbine wheel is disposed in the turbine chamber and a turbine shaft is connected to the turbine wheel. A compressor wheel is disposed in the compressor chamber and connected to the turbine shaft. A compressor back plate is adjacent to the compressor wheel and a bearing cartridge is sandwiched directly between the compressor back plate and the turbine housing and rotatably supporting the turbine shaft.
