TURBOCHARGER INSPECTION


  1. INSPECT TURBOCHARGER MOTOR


    1. A01BBDDE01

      Check the resistance.


      1. Using an ohmmeter, measure the resistance between the terminals.

        Standard resistance
        Tester Connection Specified Condition
        1 (M-) - 2 (M+) 1 to 100 Ω at 20°C(68°F)

        If the result is not as specified, replace the turbocharger.

  2. VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY


    1. A01BBLPE01

      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.

  3. INSPECT AXIAL PLAY OF TURBINE SHAFT


    1. A01BCHD

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

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

      Note

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

      Maximum axial play
      0.11 mm (0.0043 in.)

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

  4. INSPECT RADIAL PLAY OF TURBINE SHAFT


    1. A01BC62

      Using a dial indicator, insert the needle of the dial indicator into the oil outlet hole, and set it in the center of the turbine shaft.

    2. Move the turbine shaft in a radial direction and measure the radial play of the turbine shaft.

      Maximum radial play
      0.112 mm (0.0044 in.)

      If the radial play is greater than the maximum, replace the turbocharger sub-assembly.

  5. CHECK TURBINE SHAFT ROTATION


    1. A01BBML

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

      Tech Tips

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

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