Chapter 7 - Regulator & Exhaust System Overhaul
4) Hold the shaft and rotate the knob until the pin
holes line up. Use the inlet valve holder from the
regulator tool kit to accurately align these holes.
Using a small hammer drive the retaining pin back
into place, until it is flush with the surface of the
adjustment knob.
5) Screw the adjustment knob assembly clockwise
back into the regulator body leaving enough packing
nut exposed to get the wrench on it.
NOTE: Ensure the adjustment shaft rotates
smoothly.
6) Thread the packing nut onto the regulator body
and tighten with the ¾" torque wrench to 40 (after
seating) inch pounds after seating, turn the knob all
the way in and all the way out making sure there is
no interference.
7.9 Regulator & Exhaust System
Overhaul
The Kirby Morgan 37SS helmet uses a unique pod
system. The pod is designed to serve as the mount
-
ing point for the regulator. Under normal conditions,
it is not necessary to remove the pod to service the
regulator.
Note that there are two different length pod mounting
screws; six short screws and two longer screws. Also,
some of the screw heads are positioned on the outside
of the helmet shell, while others are on the inside.
The exhaust and dewatering valves are made of high
grade silicone. The exhaust and dewatering valves are
very durable and resilient however they should be
replaced at least once a year or whenever inspection
reveals any signs of damage or deterioration.
All o-rings should be replaced at least once a year
or whenever damage/deterioration is present or sus
-
pected. In order to replace the main exhaust valve,
the demand regulator must be removed from the
helmet. Removing the regulator is not difficult if
these instructions are followed.
The regulator can be removed without removing the
pod. However, during overhauls the pod should be
removed for inspection and gasket replacement.
7.9.1 Pod System and Regulator Removal
Tools required:
3/8
" socket with driver
Torque screwdriver with flat blade attachment
5/32
inch hex key
1) Remove the chin strap by removing the screws
that secure it.
This photo shows the pod with the regulator attached as it appears from the inside of the helmet. The numbers indicate the order
in which the bolts and nuts that retain the pod are loosened to disconnect the pod from the helmet. Loosen the bolts gradually,
moving from one to another.
