Reassembly of Pin Style Pressure Gauge
10. Insert o-ring (34) into the pressure indicator body (38),
making sure it is properly seated in the small recess at the
end. Place the washer (39) on top of the o-ring, inside the
pressure indicator body.
11. Install the spring (40) into the pressure indicator body
(38). Insert the plunger (41) through the center of the spring.
Place the retainer (42) on top of the plunger, press down on
the retainer and screw it into the pressure indicator body.
12. Using a 1/8" hex bit socket and flex wrench, tighten the
retainer (42) into the pressure indicator body (38) until hand
tight. Install o-ring (32) onto the threaded end of the pressure
indicator body.
13. Screw the pin pressure indicator (37) into the upper HP
port on the first stage body (8). Use the valve handle retainer
tool to tighten the pin pressure indicator until hand tight.
14. Thread the safety plug (9) into the lower HP port (opposite
the fill port) on the first stage body (8). Use a 3/8" socket and
inch pound torque wrench to apply 90 in-lbs (10.2 Nm) of
torque to the safety plug.
NOTE: DO NOT apply any type of lubricant to the safety
plug assembly (9). This will result in over-torquing of
the safety plug.
Reassembly of Blank Plug
NOTE: SEA units will either have a blank plug or On / Off
handwheel assembly. Identify which type the SEA being
serviced utilizes and follow the instructions accordingly.
NOTE: SEA systems utilizing a blank plug (22) can be
converted to use a handwheel by installing the On / Off
Valve Conversion Kit (PN 108441).
15. Install o-ring (23) onto the blank plug (22) and thread it
into the first stage body (8). Use a 3/16" hex bit socket and
inch pound torque wrench to apply 90 in-lbs (10.2 Nm) of
torque to the blank plug.
