10. Install the swivel washer(27) over the shoulder of the swivel
stem, inside the piston cap, and ensure that it is seated securely
and evenly around the base.
11. Being careful to avoid disturbing the position of the swivel
washer, mate the threaded end of the swivel retainer(24)
through the piston cap and into the stem of the swivel cap. Turn
it clockwise to engage the threads, and tighten it until finger
snug.
12. Secure the swivel cap(30) in a vise, using either the "Jaws Grip-
master," or with a vise mounting tool installed in one of the LP
ports. Ensure that the piston cap is facing up.
13. Apply an inch-pounds torque wrench with c" (8mm) hex key to
tighten the swivel retainer to a torque measurement of 80 inch-
lbs, and remove the swivel assembly from the vise.
14. Fit the large diameter end of the rubber collar(26) over the
swivel cap, and press it down until the smaller end seats into
place.
NOTE: If the first stage is going to be prepared for use in
severe conditions (cold or silty water), do not install the collar
at this time. Refer to the instructions provided at the end of
this procedure for installing the IceBreaker™ environmental
sealing collar.
15. Gently mate the piston cap straight down over the head of the
piston, and tighten the piston cap and body together by hand
until snug. (See Fig. 18.)
16. Lubricate and install the O-ring(12) onto the HP seat retainer, at
the base of the threads.
17. Install the high pressure seat(13) into the HP seat retainer(11)
with the concave dimple facing out. (See Fig. 19.)
18. Lubricate and install the O-ring(14) inside the first stage body,
using a smooth probe if necessary to ensure that it is seated
evenly over the shoulder at the base of the high pressure cham-
ber.
19. Mate the HP seat retainer into the first stage body, and turne
clockwise by hand until finger snug.
20. Secure the first stage vertically in a vise, with the LP swivel as-
sembly facing down.
21. Apply an foot-pounds torque wrench with 4" hex key to tighten
the HP seat retainer to a torque measurement of 18 foot-lbs.
22. Resecure the first stage in the vise, turned over with the LP
swivel assembly and piston cap facing straight up.
