EXHAUST MANIFOLD W/ TURBOCHARGER INSPECTION

PROCEDURE


  1. VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY


    1. B003J3ZC03
      *1 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. B003SCB

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

      Maximum axial play
      0.08 mm (0.00314 in.)

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

  3. INSPECT RADIAL PLAY OF TURBINE SHAFT


    1. B003OE5

      Insert the needle of a dial indicator into the oil outlet hole and set it against the center of the turbine shaft.

    2. Move the turbine shaft in the radial direction and measure the radial play of the turbine shaft using the dial indicator.

      Maximum radial play
      0.110 mm (0.00433 in.)

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

  4. CHECK TURBINE SHAFT ROTATION


    1. B003JER

      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.

  5. INSPECT ACTUATOR AND WASTE GATE VALVE OPERATION


    1. Disconnect the actuator hose from the compressor housing.

    2. B003QHLE01

      Using SST, apply pressure to the actuator.

      SST
      09992-00242
      Valve opening pressure
      Specified pressure* (See table below)

      Note

      Never apply more than the predetermined maximum pressure* to the actuator.

      Tech Tips

      *: For the specifications, refer to the table below.

      Specifications

      Valve Opening Pressure

      (kPa: Gauge Pressure)

      Maximum Pressure

      (kPa: Gauge Pressure)

      Rod Stroke

      (Reference)
      108 136

      2.0 to 4.50 mm

      (0.0787 to 0.177 in.)

    3. Check that the actuator push rod moves and that the waste gate valve opens.

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

    4. Reconnect the actuator hose to the compressor housing.
