Using the squared end of the stem (28), screw the seat
disc & retainer (29) into the port on the first stage body (8).
Leave the stem in position, place the handwheel (18) over
the stem and tighten the seat disc & retainer until finger tight.
Remove the handwheel from the stem.

Install o-ring (23) onto the bonnet (21) so that the o-ring
fits into the groove located above the threads. Lubricate the
bonnet threads, then pass the bonnet over the stem and
thread it into the first stage body (8) until hand-tight.
19.
Use a 3/4” socket and
inch pound torque wrench
to apply 90 in-lbs (10.2 Nm)
of torque to the bonnet (21).
20.
Place the nylon washer
(19) over the stem (28), so it
sits on top of the bonnet (21).
Face the round edge on the
indicator ring (20) outward and
thread the indicator ring onto
the bonnet until it bottoms out.
21.
When the indicator ring
(20) bottoms out, turn it
slightly counter-clockwise
so the square corners on
the stem (28) shaft are
aligned with the square
cutouts on the indicator
ring. Turn an additional 90°
counter-clockwise.
22.
Place the handwheel (18) over the indicator ring (20). Place
the spring (17) into the handwheel, followed by the washer (16).
Using the modified screwdriver, screw the handwheel retainer
(15) onto the end of the stem (28) until it will not turn any further.
CAUTION:
If resistance is felt while screwing the
handwheel retainer (15) onto the stem (28), stop
and start over to avoid cross threading.
23.
Install o-ring (12) onto the
threaded end and o-rings (13)
into the grooves on the swivel
port plug (14).
16.
In the following order,
place a new Teflon washer
(27), brass washer (26),
o-ring (25) and back-up ring
(24) onto the stem (28).
