e. Allow a few minutes for air bubbles to come
to the top and dissipate.
NOTE
A special installing and setting tool (part
No. 0644-169) is available that will grip
the end of the adjuster piston when set-
ting the height of the adjuster piston.
f. Position the adjuster piston at the distance
from the top of the body indicated in Table
2.
NOTE
If
necessary, push the piston in, then pull
the piston up, but do not puU the piston
above the level of the oil.
g. Install the relief screw and 0-ring (51 and
52, Figure 20) in the floating piston.
h. Dump excess oil from the adjuster body. Oil
without air should be below the floating
piston and air above the piston.
1.
Tum the adjuster knob
(56, Figure 20)
counterclockwise all the way out.
j. Install the cap and adjuster assembly (53-
56, Figure 20). Tighten the cap securely.
NOTE
Make sure the adjuster knob had 114-112
turn free play before contacting the pis-
ton.
If
free play is not correct, the posi-
tion of the piston may not be correct.
Units with integral reservoir
Refer to
Figure
21 for these procedures.
1. Remove the screw
(30, Figure
21) and 0-
nng.
2. Release the pressurized nitrogen carefully us-
ing the special tool (part No.
0644-158) or
equivalent.
3. If necessary, pull the eyelet to extend the rod
(2, Figure
21).
CAUTION
Do not attempt to disassemble the unit
without the proper holding fixture. Parts

are easily damaged by improper holding
procedures.
4. Clamp the body (19, Figure 21) in a special
holding fixture (part No. 0644-158) or equiva-
lent with the cap (26, Figure
21)
up.
5. Remove valve (29,
Figure
21).
6. Unscrew cap (26, Figure
21)
from the body.
Allow oil to drain from the body.
7. Make sure the body is still securely clamped
in the holding fixture (part No.
0644-158) or
equivalent and unscrew the cap (3,
Figure
21).
8. Lift the rod, cap and piston assembly from the
body.
9. Loosen, but do not remove, the nut ( 18, Fig-
ure
21).
NOTE
Do not mix the order of the valve plates
(washers). The number, size and order of
the valve plates determines dampening
action. The valve plates and piston can
be cleaned and inspected after loosening
the retaining nut, while leaving the valve
and piston on the rod. If additional dis-
assembly is required, keep these parts in
the correct order to facilitate reassem-
bly.
10. Clean and inspect the parts of the valve and
piston.
11. If any of the valve or piston parts are dam-
aged, proceed as follows:
a. Remove the nut (14,
Figure
21).
b. Withdraw the parts
(5-19, Figure
21) from
the rod, keeping the parts in the proper
order.
NOTE
When parts (5-17, Figure 21) are re-
moved, they can be temporarily installed
on a 5116 in. x 3 in. bolt to keep them
from becoming mixed up. The parts
should be installed on the bolt in the
order they are removed.
c. Install the valve and piston, making sure the
order of assembly is correct. The seven
large slots in the piston (13, Figure
21)
