Exhaust Manifold W/ Turbocharger (W/O Dpf) -- Inspection

1. VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY

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

2. INSPECT AXIAL PLAY OF TURBINE SHAFT

Using a dial indicator, insert the needle of the dial indicator into the exhaust side of the turbine shaft.
NOTICE:
Turbocharger sub-assembly and dial indicators are surely fixed when performing measurement.

Move the turbine shaft in an 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. INSPECT RADIAL PLAY OF TURBINE SHAFT

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.

Move the turbine shaft in a radial direction and measure the radial play of the turbine shaft.
Maximum radial play:
0.112 mm (0.00440 in.)
If the radial play is more than the maximum, replace the turbocharger sub-assembly.

4. CHECK TURBINE SHAFT ROTATION

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