Using a micrometer, measure the thickness of the removed shim.
(b) Calculate the thickness of a new shim so the valve clearance comes within the specified value.
T: Thickness of used shim.

N: Thickness of new shim.
Intake: N = T + (A - 0.20 mm (0.008 inch))
Exhaust: N = T + (A - 0.30 mm (0.012 inch))
(c)
Select a new shim with a thickness as close as possible to the calculated values.
