VALVE CLEARANCE (w/o DPF) ADJUSTMENT


  1. REMOVE INJECTOR ASSEMBLY

    Refer to the procedures up to "REMOVE INJECTOR ASSEMBLY" Click here.

  2. SET NO. 1 CYLINDER TO TDC/COMPRESSION

    *a Alignment Mark

    1. Align the alignment mark of the crankshaft pulley and timing gear case cover by rotating the crankshaft clockwise.

      Tech Tips

      Make sure that both cam-noses (intake side and exhaust side) of the No. 1 cylinder face upward.

  3. INSPECT VALVE CLEARANCE

    *1 Exhaust
    *2 Intake
    *a Front

    1. Check only the valves indicated.


      1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.

        Standard valve clearance (Cold)
        Intake Exhaust
        0.20 to 0.30 mm (0.008 to 0.012 in.) 0.35 to 0.45 mm (0.014 to 0.018 in.)

        Write down the valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.

    2. Turn the crankshaft 360° to set the No. 4 cylinder to TDC / compression.

      Check only the valves indicated.


      1. Using a feeler gauge, measure the clearance between the valve lifter and camshaft.

        Standard valve clearance
        Intake Exhaust
        0.20 to 0.30 mm (0.008 to 0.012 in.) 0.35 to 0.45 mm (0.014 to 0.018 in.)

        Write down the valve clearance measurements that are not within the specified range. These measurements will be used later to determine the size of the adjustment shim to be installed.

  4. ADJUST VALVE CLEARANCE


    1. Remove the camshafts Click here.

    2. Remove the 8 valve lifters.

    3. A01KF1SE01

      Using a micrometer, measure the thickness of the removed lifter.

    4. Calculate the thickness of a new lifter so that the valve clearance comes within the specified value.

      A B C
      New lifter thickness Used lifter thickness Measured valve clearance
      New lifter thickness
      Intake A = B + (C - 0.25 mm (0.0098 in.))
      Exhaust A = B + (C - 0.40 mm (0.00158 in.))

    5. Select a new lifter with a thickness as close as possible to the calculated values.

      Tech Tips

      Valve lifters are available in 35 sizes in increments of 0.020 mm (0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).

    6. Install the selected valve lifter.
