    Note: Band clamps (8), (9) and (10), are one time use parts. Discard the clamp assemblies if the clamps are loosened.

  5. Remove band clamp (8) in order to separate the adaptor from the turbine housing. Discard band clamp (8).

  6. Remove band clamp (9) in order to separate the turbine housing from the cartridge assembly. Discard band clamp (9).

  7. Remove band clamp (10) in order to separate the compressor housing from the cartridge assembly. Discard band clamp (10).

  8. Remove adapters (11) from the cartridge assembly.

Installation Procedure

Note: Check the O-ring seals, the gaskets, and the seals for wear or for damage. Replace the components, if necessary.

  1. Install the turbocharger (6) in the reverse order.

    1. Install new band clamp (9). Tighten band clamp (9) to a torque of 18 N·m (159 lb in). Loosen band clamp (9) and retighten the clamp to a torque of 13.6 ± 1.2 N·m (120 ± 11 lb in).

    2. Install new band clamp (10). Tighten band clamp (10) to a torque of 13.6 ± 1.2 N·m (120 ± 11 lb in).

    3. Install new band clamp (8). Tighten band clamp (8) to a torque of 12 ± 4 N·m (106 ± 35 lb in).

    4. Apply Tooling (A) to the threads of new nuts (7) prior to installation.

    5. Tighten nuts (7) to a torque of 70 ± 5 N·m (52 ± 4 lb ft).

    6. Put clean engine oil in the oil inlet of the turbocharger after assembly or before installation. This action will provide lubrication during start-up and during storage.
