  4. SET NO. 1 CYLINDER TO TDC/COMPRESSION


    1. A01XCB3

      Turn the crankshaft pulley and align its groove with the timing pointer.

    2. Check that the valve lifters for the No. 1 cylinder are loose and the valve lifters for the No. 4 cylinder are tight.

      If not, turn the crankshaft 1 revolution (360°) and align the mark as above.

  5. INSPECT VALVE CLEARANCE

      *1 No. 1 EX
      *2 No. 3 EX
      *3 No. 1 IN
      *4 No. 2 IN

      Check only the valves indicated in the illustration.


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

        Standard Valve Clearance (Cold)
        Item Specified Condition
        Intake 0.20 to 0.30 mm (0.00787 to 0.0118 in.)
        Exhaust 0.40 to 0.50 mm (0.0158 to 0.0197 in.)

      2. Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting shim.

      Check only the valves indicated in the illustration.


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

        Standard Valve Clearance (Cold)
        Item Specified Condition
        Intake 0.20 to 0.30 mm (0.00787 to 0.0118 in.)
        Exhaust 0.40 to 0.50 mm (0.0158 to 0.0197 in.)

      2. Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting shim.

  6. ADJUST VALVE CLEARANCE


    1. A01XGCKE01

      Remove the adjusting shim.


      1. Turn the crankshaft so that the cam lobe of the camshaft on the valve being adjusted points upward.

      2. Using SST, press down the valve lifter.

        SST
        09248-64011

      3. Position the notch of the valve lifter so that it faces the exhaust manifold side.

      4. A01XIXUE02

        Remove the adjusting shim with a screwdriver and magnet hand.

    2. A01XGRKE02

      Determine the replacement adjusting shim size according to the formula and charts below.


      1. Using a micrometer, measure the thickness of the removed shim.

      2. Calculate the thickness of a new shim so that the valve clearance comes within the specified value.

        T = Thickness of removed shim

        A = Measured valve clearance

        N = Thickness of new shim

        Intake N = T + (A - 0.25 mm (0.00984 in.))
        Exhaust N = T + (A - 0.45 mm (0.0177 in.))

      3. Select a new shim with a thickness as close as possible to the calculated value.

        Tech Tips

        Shims are available in 17 sizes in increments of 0.05 mm (0.00197 in.), from 2.50 mm (0.0984 in.) to 3.30 mm (0.130 in.).

        EXAMPLE:

        A 2.80 mm (0.110 in.) shim is installed and the measured clearance is 0.350 mm (0.0138 in.). Replace the 2.80 mm (0.110 in.) shim with a No. 21 shim.

    3. Install a new adjusting shim.


      1. Install a new adjusting shim to the valve lifter.

      2. Remove SST.

    4. Recheck valve clearance.
