19. Insert the slotted end of the Lever Installation Tool into the
open end of the valve body and over the pin, so that it is seated
directly over the washer. While holding the box bottom with
valve body secure, press the tool inward until the poppet spring
is fully compressed, and hold.
20. Locate the hole of the valve body that is directly adjacent to the
inside wall of the box bottom, above the right exhaust valve.
While holding the tool depressed, carefully insert the notched
end of the lever(5) into this hole, straight through the tail of the
poppet inside, and into the hole in the opposite side of the valve
body (see Fig. 19).
21. Remove the Lever Installation Tool to inspect the engagement
of the lever inside the valve body, to ensure that the end of the
lever is inserted as far as possible into the hole in the opposite
side of the valve body (see Fig. 20).
22. Install the O-ring(29) onto the adjustment screw(28).
NOTE: The adjustment screw is designed with left hand
threads, which is opposite of common threading.
23. Lightly lubricate the threads of the adjustment screw with a
food grade, anti-seize lubricant. Thread the adjustment screw
counter-clockwise by hand into the lever retaining sleeve; only
until lightly snug.
24. While holding the box bottom with the adjustment end of the
valve body facing straight up, position the retaining sleeve
above the opening to align the railed channel of the sleeve with
the grooved feature of the lever arm. When these two parts are
in exact alignment, gently lower the sleeve with adjustment
screw into the valve body so that the two narrower grooves seat
down evenly over the pin.
CAUTION: Do not press the retaining sleeve into the valve
body, over the lever arm. Doing so may cause damage that
will impair the correct movement of the lever, and adversely
affect the function of the regulator. If necessary, remove the
retaining sleeve from the valve body to correct the position of
the lever and/ or the retaining sleeve before proceeding.
25. Continue holding the box bottom with the valve body standing
vertically straight up, and grasp the lever firmly between thumb
and forefinger. Without applying any pressure to the retaining
sleeve, move the lever very slightly outward until the sleeve
drops lower inside the valve body (see Fig. 21). This will
positively indicate that the railed channel of the sleeve has
correctly seated over the grooved feature of the lever.
NOTE: It is important to continue holding the box bottom with
the valve body facing up, in order to prevent the retaining
sleeve from falling off of the lever arm and out of the valve
body.
26. Install the O-ring(30) securely into the groove between the
adjustment end of the valve body and box bottom.
