(b) Determine the replacement adjusting shim size by following the Formula or charts below:
^ 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 - 0.23 mm (0.009 in.))
Exhaust: N = T + (A - 0.27 mm (0.011 in.))
^ Select a new shim with a thickness as close as possible to the calculated value.
