(b) Determine the replacement adjusting shim size according to the following formula or use the Charts:
^ Using a micrometer, measure the thickness of the removed shim.
^ Calculate the thickness of a new shim so that the valve clearance comes within specified value.
T = Thickness of removed shim
A = Measured valve clearance
N = Thickness of new shim
Intake: N = T + (A -0.20 mm (0.008 in.))
Exhaust: N = T + (A -0.30 mm (0.012 In.))
^ Select a new shim with a thickness as close as possible to the calculated value.
