Step 4 - Apply O-ring grease to grooves
Use your gloved fingers to evenly spread a very thin layer of O-ring grease
(we suggest Molykote 55 ) – enough to make the area appear shinny –
around the O-ring surface on the inside of the Outer Cylinder (the smooth
area between the threads and the end of the case). You shouldn’t be able to
see grease globs or streaks. This thin layer of grease will make screwing
the two pieces together again much easier and will also help to create a
better seal.
Step 5 - Apply O-ring grease to O-ring
While you have grease on your glove, evenly spread grease over the entire
surface of the O-ring until the O-ring is slippery, but doesn’t have clumps of
grease on it. Too much grease can cause an O-ring to “pop” out of the groove
while the case is being closed, giving little protection from water entering the
HR2.
7.2.3 Installing O-Rings
Now that the O-rings and O-ring surfaces are clean and prepared, we’re ready
to
install the new O-rings into the case.
1. Slowly move one of the O-rings along the body of the HR2 to the end
cap and carefully lift it over the threads.
2. Push the O-ring into the top O-ring groove and check the circumference of
the receiver to make sure the entire O-ring is in the groove.
3. Slowly move the second O-ring over the HR2’s body, over the threads,
and into the other groove. Check that it’s entirely in the groove.
4. Clean any grease that may have gotten on the body of the receiver.
5. Place the receiver on a clean surface so the O-rings remain debris and
damage free.
For information on closing back the receiver, see "Closing the HR2 Case", on page 155 .
