N Thickness of new shim

Intake N = T + (A - 0.20 mm (0.008 in.)) Exhaust N = T + (A - 0.25 mm 10.010 in.))

• Select a new shim with a thickness as close as possible to the calculated values.

NOTE: Shims are available in seventeen sizes of 0.05 mm (0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 mm (0.1299 in ).
