Seal Removal and Disassembly
(Figure 2)
Remove the impeller adjusting shims (4). Tie and
tag the shims or measure and record their thick-
ness for ease of reassembly.
Remove the seal spring and slide the shaft sleeve
(5) and rotating portion of the seal off the engine
shaft as a unit. Apply oil to the sleeve and work it up
under the bellows. Slide the rotating portion of the
seal off the sleeve.
Slide two stiff wires with hooked ends along the
shaft and pull stationary seat and O-ring from the
intermediate bore.
NOTE
An alternate method of removing the stationary seat
is to remove the hardware (19 and 20, Figure 1 or
Figure 2) and separate the intermediate (6) from the
engine. Use a dowel to press the stationary seat
and O-ring from the intermediate.
If the seal ring (7) requires replacement, remove
the intermediate as described above, and slide the
seal ring off the shaft.
If no further disassembly is required, refer to Seal
Reassembly And Installation.
Seal Reassembly and Installation
(Figures 2 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 contain-
ers.
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 3).
