between the outer terminal bushing and the surface of
the mounting plate. This is to provide further crush of
theterminalbushing incasealeakshould occur. Tostop
a leak, tighten the terminal bushing nut only enough to
stop the escape of gas. Do not tighten until the terminal
bushingis fl ush withthem ounting plate. Thetightening
torque used at the factory is 0.21 to 0.23 mkg (18 to 20
inchpounds)maximum toprevent damageto theplastic
