5.
Check assembled height (A) in at least four places, 90°
apart. The difference in height around the ring must not
be more than 1 mm (.04 in).
6.
If small adjustments are necessary, do not push directly
on seal ring (1); use installation tool (9).
7.
Toric ring (2) can twist if it is not wet all around during
installation or if there are burrs or fins on retaining lip (3)
of housing (5).
NOTICE
Misalignment, twists and bulges of the toric will cause
Duo-Cone Seal failures. If correct installation is not
obvious, remove seal from housing and repeat Steps 3
thru 6.
NOTE:
Toric rings (2) must never slip on the ramps of
either seal rings (1) or seal ring housings (5). To
prevent slippage, wait a minimum of two minutes
to let the Isopropyl alcohol evaporate before
further assembly. Once correctly in place, the
toric ring must roll on the ramps only.
8.
Wipe seal faces (6) of seal rings (1) clean. Use a lint
free cloth or paper towel. No particles of any kind are
permissible on the sealing surfaces. Even a small piece
from a paper towel can hold the seal faces apart and
cause leakage.
