    *1 Turbine Wheel - -

    1. 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.

      Tech Tips

      The cut part indicated in the illustration at A is normal and does not indicate that the turbine wheel is damaged.

  2. CHECK TURBINE SHAFT ROTATION


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

      A01INQFE01

      Tech Tips

      Due to the viscosity of the oil, it may take 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.

    2. Move the turbine wheel as shown in the illustration and check that there is no looseness in the shaft and that the turbine wheel does not contact the housing.

      A01IO2SE01

      If there is any contact with the housing or any looseness in the shaft, replace the turbocharger sub-assembly.

  3. INSPECT ACTUATOR AND NOZZLE VANE OPERATION

    A01IQ12E01

    1. Connect a vacuum pump to the actuator.

    2. When applying vacuum to the actuator, check that the rod moves smoothly toward the actuator and that the nozzle vane moves.

      Tech Tips

      Visually check the movement by looking inside the turbocharger from the area where the turbocharger connects to the exhaust manifold.

      If the rod does not move, replace the turbocharger sub-assembly.
