      *a Compressor Impeller

      Check for deformation and cracks in the compressor impeller on the intake side.

      If the compressor impeller is cracked or deformed, replace the turbocharger sub-assembly.

      *a Turbine Wheel

      Check for deformation and cracks in the turbine wheel on the exhaust side.

      If the turbine wheel is cracked or deformed, replace the turbocharger sub-assembly.

  2. INSPECT AXIAL PLAY OF TURBINE SHAFT


    1. Using a dial indicator, insert the needle of the dial indicator into the exhaust side of the turbine shaft.

      Note

      Turbocharger sub-assembly and dial indicators are surely fixed when performing measurement.

    2. A003C4C

      Move the turbine shaft in the axial direction and measure the axial play of the turbine shaft.

      Maximum axial play
      0.11 mm (0.00433 in.)

      If the axial play is more than the maximum, replace the turbocharger sub-assembly.

  3. CHECK TURBINE SHAFT ROTATION


    1. A003AMB

      Rotate the turbine wheel on the exhaust side with your finger and check that it rotates smoothly.

      Tech Tips

      Even if it takes a little effort to rotate the turbine wheel, this is not a problem.

      If the turbine wheel does not rotate smoothly, replace the turbocharger sub-assembly.

  4. INSPECT TURBOCHARGER NOZZLE VANE CONTROL ACTUATOR


    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 - 2 20°C (68°F) 1 to 100 Ω

      Tech Tips

      The temperature indicated in "Condition" is the temperature of the turbocharger nozzle vane control actuator.

      If the result is not as specified, replace the turbocharger nozzle vane control actuator.
