Step 2:

Use the supplied brush to apply a third of the UCN lubricant to the sealing ring channel on the end

cap (Figure 24).

Step 3:

Stretch the sealing ring over the channel.

Step 4: Fold the edge of the seal that overlaps the outside of the end cap until the seal seats in the channel as

shown in Figure 25.

Step 5:

Retain a small amount of UCN lubricant for later use. Apply the remaining lubricant to all sides of the

sealing ring.

Install the Canister Cover.

Step 1:

Slide the canister over the closure assembly.

Step 2:

Loosen bolt on the hinged side of the clamping ring.

Step 3:

Apply a thin coat of UCN lubricant retained previously to the threads of the clamping ring latch bolts

to prevent the bolts from seizing on reentry.

Step 4: Place the clamping ring over the flange of the canister and the sealing ring. Ensure that both the

sealing ring and the canister flange are within the clamping ring (Figure 26).

Step 5:

Swing the clamping ring into closing position. Tighten the bolts until the plastic on the ring touches,

then tighten a quarter turn until the ring is completely closed.

IMPORTANT:

A torque value of 25 to 50 in-lb should be sufficient to close the clamping ring. Do not use power

tools to tighten the ring; a torque value of more than 80 in-lb causes the hardware to crack and

the clamping ring to become defective. If the clamping ring does not close properly, make sure the

sealing ring and clamping ring are oriented correctly.
