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. If any components are worn, replace the com­
plete 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 and stationary element O‐ring with water or a
very small amount of light lubricating oil, and apply
a drop of light lubricating oil on the finished faces.
Assemble the seal as follows, (see Figure 2).

Subassemble the O‐ring onto the stationary ele­

sembly into the seal plate until it seats squarely
against the shoulder bore.
Carefully slide the assembled seal plate and sta­
tionary seal element over the shaft. Use caution not
to nick or damage the stationary seat. Use two
