    VISUALLY CHECK TURBOCHARGER SUB-ASSEMBLY


    1. A01INAOE01

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

    CHECK TURBINE SHAFT ROTATION


    1. A01IR6G

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

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

      Tip:

      Due to the viscosity of the oil, it may take a little effort to rotate the turbine wheel. This is not a problem.

    2. A01ISWG

      Move the turbine wheel as shown in the illustration and check that there is no looseness in the shaft and that the turbine wheel does not contact the housing.

      If there is any contact with the housing or obvious looseness in the shaft, replace the turbocharger sub-assembly.

      Tip:

      A clearance on the order of 100 μm exists between the turbine shaft and bearings. If it is difficult to judge the looseness of the turbine shaft, perform the same inspection on another vehicle which has the same turbocharger sub-assembly and compare the clearance.
