MAINTENANCE & REPAIR PAGE E - 8
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 O‐
rings and shaft sleeve with water or a very small
amount of oil, and apply a drop of light lubricating
oil on the finished faces. Assemble the seal as fol­
lows, (see Figure 3).

This seal is not designed for operation at
temperatures above 160

If the intermediate (20) was removed, lay it on a flat
surface with the impeller side facing up. If the wear
ring (21) was removed for replacement, press the
replacement ring into the intermediate (20) until it
seats squarely against the shoulder bore.
The wear ring must seat squarely in the in­
termediate bore or binding and/or exces­
sive wear will result.
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 bellhousing with the hardware (18 and
19). When installing the intermediate, use caution
