a. Position the piston insertion tool on the end of the ICM as shown in step 1 in
Figure 5-11. Note that the clevis assembly needs to be removed for this
procedure.
b. Apply a small film of Krytox silicon lubricant to the o-ring (), seal (), and
centering ring () As in Figure 5-10. Ensure that excessive Krytox silicon
lubricant is not at the tip of the piston seals. Do not let Krytox work its way to the
ICM inlet valve.
c. Carefully and slowly insert piston seal into insertion tool and then into ICM
cylinder as shown in step 2. Move the piston back and forth in the ICM cylinder
several times to allow the seals to form to the cylinder wall.
d. Remove the piston insertion tool and keep the piston in the ICM cylinder.
e. Apply a small amount of Loctite 222 to piston threads. Install the clevis assembly
on the end of the piston. To tighten, use the hex tool as illustrated in steps 4 and 5
