12. Install o-ring (17) onto the bonnet (18) so that the o-ring
fits into the groove located above the threads. Lightly lubricate
the bonnet threads, then pass the bonnet over the stem (12)
and thread it into the first stage body (8) until hand-tight.
13. Attach a 3/4" deep socket
to a torque wrench and torque
the bonnet (18) to a value of
90 in lb / 10.2 Nm.
14. Place the nylon washer
(20) over the stem (12), so it
sits on top of the bonnet (18).
Face the round edge on the
indicator ring (19) outward
and thread the indicator
ring onto the bonnet until it
bottoms out.
15. When the indicator ring
(19) bottoms out, turn it slightly
counter-clockwise so the
square corners on the stem
(12) shaft are aligned with the
square cutouts on the indicator
ring. Turn an additional 90°
counter-clockwise.
16. Place the handwheel (21) over the indicator ring (19). Insert
the spring (22) into the handwheel, followed by the washer (23).
Using the modified screwdriver, tighten the handwheel retainer
(24) onto the end of the stem (12) until it will not turn any further.
CAUTION: If resistance is felt while screwing the
handwheel retainer onto the stem, stop and start over
to avoid cross threading.
17. Wrap the QD connector (9)
with 3 1/2 to 4 1/2 revolutions
of oxygen compatible ¼"
Teflon tape.
18. Only rotate the CPC connector clockwise when tightening.
Torque the CPC connector (9) with a 5/8" crowfoot and torque
wrench to a value of 60 in lb / 6.8 Nm. Ensure the release
button is oriented on top.
CAUTION: Make sure to align the wrench properly on the
CPC connector to avoid damaging the release button.
