Check 

  1. Remove the valve cover. Refer to: Valve Cover  .
  2. NOTE: Only rotate the crankshaft clockwise.

    Rotate the crankshaft until the corresponding piston is at TDC and then measure the valve clearance(s). Use the General Equipment: Feeler Gauge

  3. Note down each cylinder number and the valve clearances measured.
  4. Compare the measured valve clearance(s) with the specifications. Refer to: Specifications  .

    • Remove the valve tappet and read the thickness from the underside.

    • The number on the valve tappet indicates the thickness of the bottom of the tappet. However, the number only indicates the digits after the decimal point (example: 725 = 2.725).

    • Calculate the required thickness of the valve tappet with the following formula: X = S + M - V

    • Required thickness of tappet = X

    • Thickness of currently fitted tappet = S

    • Measurement of existing valve clearance (actual value) = M

    • Desired valve clearance = V

  8. Install the correct valve tappet.
  9. NOTE: Make sure that the components are installed to the position noted before removal.

    Lubricate and install the camshafts approximately at valve overlap position cylinder No. 1.
