MAINTENANCE & REPAIR PAGE E - 11
The seal is not normally reused because wear pat­
terns on the finished faces cannot be realigned
during reassembly. This could result in premature
failure. If necessary to reuse an old seal in an emer­
gency, carefully wash all metallic parts in fresh
cleaning solvent and allow to dry thoroughly.
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 shaft
sleeve O‐ring and the external stationary seat O‐
ring with a very small amount of light lubricating oil.
See Figure 5 for seal part identification.

C). Do not
use at higher operating temperatures.
If the seal plate was removed, install the seal plate
gasket (4). Position the seal plate over the shaft
and secure it to the bearing housing with the hard­
ware (5 and 6).
To prevent damaging the shaft sleeve O‐ring (29)
on the shaft threads, stretch the O‐ring over a piece
of tubing 1‐1/4 I.D. x 1‐1/2 O.D. x 2‐inches long (32
mm x 38 mm x 51 mm). Slide the tube over the shaft
threads, then slide the O‐ring off the tube and onto
the shaft. Remove the tube, and continue to slide
the O‐ring down the shaft until it seats against the
shaft shoulder.
When installing a new cartridge seal assembly,
remove the seal from the container, and remove
the mylar storage tabs, if so equipped, from be­
tween the seal faces.
