6.7 Select O-ring [13] and stretch slightly. Lightly lubricate with silicone grease.
Install O-ring [13] into the gland assembly [11]. See Figure 10.
6.8 For sizes ≤ 2.750 inch (70 mm) install the
vibration dampener [183.1] onto the gland
surface where the stationary face [14] will be

installed. See Figure 11.
For sizes > 2.750 inch (70 mm) install the
long end of the ed drive pin [5] into the hole
in the gland where the stationary face [14]
will be located. Cut a 0.25 inch (6 mm) slot
in the vibration dampener [183]. See Figure
11. Install onto the gland surface where the
stationary face will be installed with the slot
positioned around the drive pin.
6.9 Select stationary face [14] and lightly lubricate
the O-ring surface using silicone grease.
Install the stationary face [14] into the gland/
vibration dampener assembly [183.1 and 11].
Use hand pressure only. See Figure 12.
For sizes ≤ 2.750 inch (70 mm) ensure that
the flats on the stationary face [14] and the
flats on the gland assembly [11] are aligned.
For sizes > 2.750 inch (70mm) ensure that
the slot on the stationary face [14] and the
square-headed pin [5] are aligned.
6.10 Check for proper seating of the stationary
face by measuring from the back of
the gland assembly to the face of the
stationary face with a caliper or depth
gage. Measure in 3 equally spaced
locations, measurement variations should
not exceed 0.005 inch (0.127 mm).
6.11 Clean the sealing face of the stationary face
[14] to remove any dirt, dust, finger prints,
grease or any other residue using ethyl
alcohol on a clean cloth or tissue.
6.12 Install the gland [11] onto the sleeve
assembly [1]. See Figure 13.
