Kirby 37 appendix Reinstalling the Quad-Valve Exhaust Assembly, 101

Kirby Morgan 37 & 57

7.11Reinstalling 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)

3)Reinstall the bent tube assembly and tighten the jam nut to 40 inch pounds.

4)Retighten the regulator mount nut to 75 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.
