finished faces; even fingerprints on the faces can
shorten seal life. If necessary, clean the faces with a
non-oil based solvent and a clean, lint-free tissue.
Wipe lightly in a concentric pattern to avoid
scratching the faces.
Inspect the seal components for wear, scoring,
grooves, and other damage that might cause leak-
age. Clean and polish the shaft sleeve, or replace it
if there are nicks or cuts on either end. If any com-
ponents are worn, replace the complete seal;
never mix old and new seal parts.
If a replacement seal is being used, remove it from
the container and inspect the precision finished
faces to ensure that they are free of any foreign
matter.
To ease installation of the seal, lubricate the bel-
lows with water or a very small amount of light lu-
bricating oil, and apply a drop of light lubricating oil
on the finished seal faces. Assemble the seal as fol-
lows (see Figure 3).

Figure 3. S298 Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
If the seal plate (18) was removed, lay it on a flat
surface with the impeller side facing up. Lightly lu-
bricate the O.D. of the stationary seat and use your
thumbs to press the stationary seat and element
into the seal plate bore until fully seated.
Slide the assembled seal plate and stationary ele-
ment over the impeller shaft (9) and temporarily se-
cure the seal plate to the pedestal (12) using two
capscrews and nuts (1/2 UNC X 1 1/2 inch long,
not supplied).
Subassemble the rotating element into the retainer
and bellows, then slide this subassembly onto the
shaft sleeve (46) until the face of the rotating ele-
ment is just flush with the chamfered end of the
sleeve.
Slide the assembled seal and shaft sleeve onto the
shaft until the seal faces contact. Continue to push
