1. 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.

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

   Maximum axial play:
     0.08 mm (0.0031 in.)
   If the axial play is greater than the maximum, replace the turbocharger sub-assembly.

2. INSPECT RADIAL PLAY OF TURBINE SHAFT

1. 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.

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

   Maximum axial play:
     0.110 mm (0.0043 in.)
   If the radial play is greater than the maximum, replace the turbocharger sub-assembly.

3. INSPECT ACTUATOR AND WASTE GATE VALVE OPERATION

1. Disconnect the actuator hose from the compressor housing.

1. Using SST, apply pressure to the actuator.

   SST
     09992-00242

   Standard pressure:
     114 kPa (1.16 kgf/cm2, 16.5 psi)

   NOTICE:
     Never apply more than 147 kPa (1.5 kgf/cm2, 21.3 psi) of pressure to the actuator.

1. Check that the actuator push rod moves and that the waste gate valve opens.
   If the rod does not move, replace the actuator or turbocharger sub-assembly.

1. Connect the actuator hose to the compressor housing.
