Turbocharger Inspection

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.

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

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

NOTICE:

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

Maximum axial play:

0.11 mm (0.0043 in.)

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 (0.0044 in.)

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.
