Before you start

  • Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life.
  • Do not attempt to disassemble the turbocharger cartridge assembly or wastegate. Do not remove the compressor wheel. The turbocharger cartridge assembly and the wastegate are not field serviced, and should be replaced only as a unit.

Procedure

  1. Position the turbocharger on a bench. Remove clamp (1) from waste gate.
  2. Loosen the nuts on V-band clamps (3).
  3. Separate the compressor housing (2) and turbine housing (5) from turbocharger cartridge (4).
  4. Check condition of all components. Use new parts to replace worn or damaged parts.
