Step 2:
Use the supplied brush to apply a third of the UCN lubricant to the sealing ring channel on the end
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
Step 5:
Retain a small amount of UCN lubricant for later use. Apply the remaining lubricant to all sides of the
sealing ring.
12.2 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
.
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.
