d. Using a small screwdriver and magnetic finger, remove the adjusting shim.
e. Using a micrometer, measure the thickness of the removed shim.
f.
Calculate the thickness of a new shim so that the valve clearance comes within the specified value.
g. Select a new shim with a thickness as close as possible to the calculated values.
EXAMPLE (Intake):
Measured valve clearance = 0.45 mm (0.0177 inch)
0.45 mm (0.0177 inch) - 0.20 mm (0.0079 inch) = 0.25 mm (0.0098 inch)
(Measured - Specification = Excess clearance)
Used shim measurement= 2.80 mm (0.1102 inch)
0.25 mm (0.0098 inch) + 2.80 mm (0.1102 inch) = 3.05 mm (0.1201 inch)
(Excess clearance + Used shim = Ideal new shim)
Closest new shim = 3.05 mm (0.1201 inch)
Select No. 12 shim
