5.
- 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).

6.
- 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

7.

Install the correct valve tappet.
