(b) Determine the replacement adjusting shim size according to the following Formula or Charts on the next 2 pages:
• Using a micrometer, measure the thickness of the removed shim.
• Calculate the thickness of a new shim so the valve clearance comes within specified value.
T ......... Thickness of used 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 values.
HINT: Shims are available in 17 sizes in increments of 0.050 mm (0.0020 in.), from 2.500 mm (0.0984 in.) to 3.300 mm (0.1299 in.).
