6.4 Select rotating face [15] and lightly lubricate the
O-ring surface. Install the rotating face [15] into
the sleeve assembly [1]. Use hand pressure
only. See Figure 13.
For sizes ≤ 2.750 inch (70 mm) ensure that the
flats on the rotating face are aligned with the flats
on the sleeve.
For sizes > 2.750 inch (70 mm) ensure that the
drive slots on the rotating face are aligned with
the square-headed drive pin in the sleeve.
6.5 Check for proper seating of the rotating face
by measuring from the back of the sleeve
assembly to the face of the rotating face with
a caliper or micrometer. Measure in 3 equally
spaced locations; measurement variations
should not exceed 0.005 inch (0.127 mm).
6.6 Clean the sealing face of the rotating face [15]
to remove any dirt, dust, fingerprints or any other
residue using alcohol on a clean cloth or tissue.
6.7 Select O-ring [13] and lightly lubricate it. Install the
O-ring onto the stationary face [14]. See Figure 14.
6.8 Select the stationary face support [100] and the
square-headed pins [5]. Dab silicone grease on
the tip of each pin before inserting into the
stationary face support to assist keeping the
pins in place. See Figure 15.
6.9 Install the stationary face support [100] onto the
stationary face [14], maintaining alignment of the
pins in the stationary face support with the slots in
the stationary face [14]. Inspect for proper pin
engagement. See Figure 16. Note: for ease of
installing the stationary face support, a light
coating of silicone grease may be applied to
the O-ring bore.
6.10 Dab one end of the springs [16] in silicone grease
and insert the greased end into the holes in the
stationary face support [100]. See Figure 17.
Silicone grease helps hold the springs in place
but careful handling remains essential.
6.11 Clean the sealing face of the stationary face [14]
to remove any dirt, dust, fingerprints or any other
residue using alcohol on a clean cloth or tissue.
