2.2 Scribe mark B, Figure 1, at the seal setting point shown on the
assembly drawing included with the seal. (This is the seal setting
dimension as measured from the face of the seal housing to the
back of the bellows drive collar. The back of the bellows drive collar
will be located at this point. See Figure 3 for the correct installed
operating length dimension
R (l
1
). This dimension can be used
to calculate the seal setting point B if no assembly drawing is
available.
2.3 Lightly lubricate the stationary face mounting O-ring with the silicone
lubricant provided with the seal and install the O-ring in the gland.
2.4 Lightly lubricate the stationary face gasket shoulder and carefully
press the face into the seat gasket O-ring in the gland. Use hand
pressure only. All standard CBR stationary faces are supplied with
holding pins. Locate the pin to engage the pin slot in the gland to
avoid over compressing the bellows assembly.
2.5 Install the gland with the stationary face over the shaft. Place the
gland as close to the bearing bracket as possible. Do not bump the
stationary face against the shaft as it may chip, crack, or break.
2.6 Lightly lubricate the shaft or sleeve lightly with silicone lubricant.
2.7 Lightly lubricate the Bellows adapter gasket O-ring with silicone
lubricant and install the O-ring in the bellows drive collar end
groove.
2.8 Install the CBR bellows assembly with the bellows rotating face
gasket O-ring in place onto the shaft or sleeve. Do not compress
the CBR bellows assembly more than the indicated working length
R (l
1
) shown on the assembly drawing. Excessive compression may
destroy the capability of the seal to operate properly.
2.9 Set the back of the CBR bellows assembly at reference mark B,
Figure 1, and tighten set screws firmly and evenly. The rotating
bellows assembly is now in the proper position to provide the
correct setting and spring compression for final assembly.
2.10 Wipe the seal faces clean with alcohol before completing equipment
assembly. Seal faces should not be lubricated, but should be left
clean and dry.
2.11 Assemble the pump.
