4) Measure the thickness of the removed shim using a micrometer.
5) Calculate the thickness of a new shim so that the valve clearance comes within the specified value.
Valve clearance
(Engine coolant temperature: 20°C ± 5°C[68°F ± 9°F])
T: Thickness of removed shim
A: Measured valve clearance
In: Thickness of new shim
Intake: N = T + [A - 0.20mm(0.0079inch)
Exhaust: N = T + [A - 0.28mm(0.011 inch)
6) Select a new shim with a thickness as close as possible to the calculated value. (Refer to the Adjusting shim selection chart)
NOTE: Shims are available in 20 size increments of 0.04mm (0.0016inch) from 2.00mm (0.0787 inch) to 2.76mm (0.1087 inch)
7) Place a new adjusting shim on the valve lifter.
8) Using the SST(09220 - 20000), press down the valve lifter and remove the stopper.
9) Recheck the valve clearance.

[Specification]
Intake: 0.20 mm (0.0079 inch)

[Limit] (After adjusting valve clearance)
Intake: 0.17 - 0.23 mm (0.0067 - 0.0091 inch)
Exhaust: 0.25 - 0.31 mm (0.0098 - 0.0122 inch)
