3. NOTE: Only rotate the crankshaft clockwise.

   Rotate the crankshaft until each piston is at top dead center (TDC) and measure the valve clearance(s) using a suitable set of feeler gauges.

4. Measure and note the valve clearance values. Use the General Equipment: Feeler Gauge
5. Compare the measured valve clearance(s) with the specifications. Refer to: Specifications  .

Adjustment 

1. NOTE: The following steps are only necessary if adjustment is required.
2. Refer to: Camshafts  .
3. • 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:650 = 3, 650).

4. • 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

5. Install the correct valve tappet.
6. Refer to: Camshafts  .
7. Measure and note the valve clearance values.
8. Compare the measured valve clearance(s) with the specifications. Refer to: Specifications  .
9. Repeat the procedure as necessary until all valve clearances are within the specified tolerance.
