7.12 Reinstalling the Quad-Valve™
Exhaust Assembly
Once the Quad-Valve™ exhaust has been reassem-
bled, it may be mounted back on the helmet.
1) Begin to re-install the demand regulator into the
mounting hole in the helmet shell, but insert it only
about halfway in. This will allow the stainless steel
adapter cover to align easier with the main exhaust
body.
Start the cover straight onto the main exhaust body,
then alternate back to inserting the regulator. Do this
until both are in their proper positions. Lubricate
the regulator seal o-ring and hand start the regulator
mount nut.
2) Lubricate and install the 2 o-rings and install onto
the washer head screws. Using either a flat blade
screwdriver or a ¼ nut driver, fully engage the screws.
Tighten until snug. TIP: the ¼" hex tool found in the
Kirby Morgan regulator tool kit works very well for
this purpose. (Part #525-620)
Note: Refer to "7.8.9 Reassembly of the SuperFlow
350 Demand Regulator" on page 87
3) Reinstall the bent tube assembly and tighten the
jam nut to 40 inch pounds.
4) Retighten the regulator mount nut to 100 inch
pounds.
5) Reinstall the 4 spacers, kidney plates and screws
and torque to 12 inch pounds.
6) Attach any other components that may have been
displaced to aid in this installation.
