REASSEMBLY PROCEDURES
1.
If the exhaust valve (13) was removed, thread the tail
through the retaining hole on the outside of the box
bottom until the barb engages on the inside. If it is a
new valve, cut the excess stem with side cutters leaving
approximately 5mm of the tail behind.
2.
Soak the exhaust tee in
hot water (~125°F) for 2
to 3 minutes. Install the
exhaust tee (14) onto the
flange on the outside of
the box bottom. Begin by
hanging the exhaust tee
on the top of the flange,
then press the bottom of
the tee into place.
3.
Install a new, lubricated o-ring (28) onto the stem of the
shuttle valve (27). Press a new low pressure seat (26)
into the front of the shuttle valve.
4.
Fit the valve spring (29)
onto the leading edge of
the counterbalance cylin-
der (30). Carefully guide
the stem of the shuttle
valve through the spring
and into the counterbal-
ance cylinder.
5.
If you removed the lever,
replace it so that the lever
is on the same side as the
small dimple on the valve
body and the outlet port is
pointing to the right as the
threaded inlet side faces
away from you.
6.
With the "feet" of the shuttle valve pointing downward
(away from the lever) and the lever pointing straight up
(perpendicular to the valve body), insert the valve as-
sembly into the valve body. Using your finger, press the
shuttle valve assembly all the way into the valve body,
pass the lever feet. To make sure the shuttle valve as-
sembly is installed correctly, hold the valve body by the
threaded end. The shuttle valve should stay in the valve
body.
7.
Install a new, lubricated o-ring (22) onto the valve body
(23). Install a new, lubricated o-ring (32) onto the adjust-
ment knob.
8.
Install a new, lubricated o-ring (35) onto the adjustment
screw (36). Using a 4mm hex wrench, thread the adjust-
ment screw into the adjustment knob (33) until it stops.
Preadjust the adjustment screw as follows:
a.
For Legend
LX: Rotate the adjustment screw
counterclockwise for two complete turns.
b.
