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. Discard the spring centering washer in­
cluded with the seal. It is not used in this applica­
tion (see Figure 3).
To ease installation of the seal, lubricate the bel­
lows, sleeve and 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 3).

This seal is not designed for operation at
temperatures above 160
_F (71_C) Howev­
er most petroleum products such as gaso­
line are more efficiently handled at ambient
temperatures. Do not use at higher operat­
ing temperatures.
If the intermediate (12) was removed, lay it on a flat
surface with the impeller side facing up.
Subassemble the O‐ring onto the stationary seat
and press this subassembly into the intermediate
bore until it seats squarely against the shoulder.
Slide the assembled intermediate and stationary
seat over the shaft and secure the intermediate to
the engine with the hardware (10 and 11). When in­
stalling the intermediate, use caution not to dam­
age the stationary seat on the shaft threads.
NOTE
If the intermediate was not separated from the en­
gine during disassembly, subassemble the O‐ring
into the stationary seat and use a piece of plastic
