the fill adapter port (23) to 90±3 in/lbs.
CAUTION:
Do not over torque. Damage will
result to the fill adapter port.
9. SeA LV-2 with a pin-type pressure indicator (27a):
a. Drop a new, lubricated o-ring (27c) into the pin indicator
body (27b); make sure it is properly seated in the small
recess inside the body. Drop the washer (27d) over the
o-ring, making sure it is laying flat atop the o-ring.
b. Insert the spring (27e) into the indicator body and insert
the pin (27f) into the spring. Place the retaining screw
(27g) on top of the pin and press the retaining screw
against the indicator body. While keeping the retaining
