OIL PUMP (w/o DPF) INSPECTION


  1. REMOVE OIL PUMP RELIEF VALVE

    A01KEQQ

    1. Remove the plug, gasket, spring and relief valve from the timing gear case.

  2. INSPECT OIL PUMP RELIEF VALVE

    A01KFJ4

    1. Coat the relief valve with engine oil and drop it into the relief valve hole.

    2. Check that the relief valve falls in smoothly by its own weight.

      If it does not, replace the relief valve.

      If necessary, replace the timing gear case.

  3. INSPECT OIL PUMP

    A01KFBSE06

    1. Install the driven rotor into the timing gear case with the mark facing the cylinder block side.

      Check the tip clearance.


      1. Using a feeler gauge, measure the clearance between the drive and driven rotor tips.

        Tip clearance
        Specification Clearance
        Standard

        0.06 to 0.16 mm

        (0.0024 to 0.0063 in.)
        Maximum

        0.21 mm

        (0.0083 in.)

        If the tip clearance is greater than the maximum, replace the timing gear case.

    3. A01KG6J

      Check the body clearance.


      1. Using a feeler gauge, measure the clearance between the oil pump body and driven rotor.

        Body clearance
        Specification Clearance
        Standard

        0.10 to 0.17 mm

        (0.0039 to 0.0067 in.)
        Maximum

        0.20 mm

        (0.0079 in.)

        If the body clearance is greater than the maximum, replace the timing gear case.

    4. A01KI9Z

      Check the side clearance.


      1. Using a feeler gauge and precision straightedge, measure the clearance between the driven rotor and precision straightedge.

        Side clearance
        Specification Clearance
        Standard

        0.03 to 0.09 mm

        (0.0012 to 0.0035 in.)
        Maximum

        0.15 mm

        (0.0059 in.)

        If the side clearance is greater than the maximum, replace the timing gear case.

  4. INSTALL OIL PUMP RELIEF VALVE

    A01KEQQ

    1. Install the relief valve and spring into the timing gear case.

    2. Install a new gasket and plug to the timing gear case.
