NOTE
• The sealant is applied to both sides of the soft metal gasket
shim. The liquid gasket is not required for assembling.
• Addition or reduction of shim (0.05 mm, 0.002 in.) delays or
advances the injection timing by approx. 0.009 rad (0.5 °).
• In disassembling and replacing, be sure to use the same
number of new gasket shims with the same thickness.
