5.
Measure dimension (A) from seal ring face (6) to the top
surface of seal ring housing (5). Check dimension (A) in
at least four places (90 degree intervals). The
measurements must not differ by more than 1 mm (0.04
in).
NOTE:
If small adjustments are necessary, do not push
directly on seal ring (1). Use installation tool (9).
6.
Rubber toric ring (2) can twist if the toric ring is not
completely wet during installation. Burrs on housing
retaining lip (3) or on seal ring housing (5) can also
cause a twist.
If a twist occurs or if the toric ring is misaligned, repeat
Steps 3 through 5.
7.
Before further installation, wait at least two minutes so
that the isopropyl alcohol can evaporate. This will
prevent slippage on seal ring ramps (7) and on housing
ramps (4). The toric ring must roll only on the seal ring
ramps and on the housing ramps.
8.
Use a clean cloth or a paper towel to wipe off seal ring
faces (6).
NOTE:
No particles of any kind can be left on the sealing
surfaces. A small piece from a paper towel can
cause a leak by keeping the sealing surfaces from
contacting each other.
9.
Apply a thin film of clean oil on seal ring faces (6). Use
an applicator, a disposable tissue or a clean finger to
distribute the oil evenly. Be careful so that no oil
contacts the rubber toric rings.
