MAINTENANCE & REPAIR
PAGE E - 11
Reusing an old seal could result in prema
ture failure.
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.

Figure 5. Cartridge 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 was removed, install the seal plate
gasket (6). Position the seal plate over the shaft
and secure it to the bearing housing with the hard
ware (8 and 9).
To prevent damaging the shaft sleeve O‐ring (4) on
the shaft threads, cover the threads with electrical
or duct tape. Slide the O‐ring over the shaft until it
seats against the shaft shoulder. Remove the tape
covering the threads. Check to ensure that the
shaft threads are free of any tape residue and clean
as required before proceeding with seal installa
tion.
Lubricate the external stationary seat O‐ring with
light oil. Slide the seal assembly onto the shaft until
