Use a pair of stiff wires with hooked ends to hook
the stationary element from the back side, and pull
the element and O‐ring from the seal plate bore.
Remove the sleeve O‐ring (17).
If no further disassembly is required, proceed with
PUMP AND SEAL REASSEMBLY . If the gearbox
requires disassembly, do not reassemble the
pump components at this time. Refer to

Seal Reassembly and Installation
(Figures 1 and 3)
Clean the seal cavity and shaft with a cloth soaked
in fresh cleaning solvent.
Most cleaning solvents are toxic and
flammable. Use them only in a well‐ven­
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent
containers.
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.
Handle the seal parts with extreme care to prevent
damage. Be careful not to contaminate precision
finished faces; even fingerprints on the faces can
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. 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 E-3).
