MAINTENANCE & REPAIR PAGE E - 12
Lubricate the bearing cover O‐ring (63) and install it
in the groove in the bearing cover.
Install the wave washer (38) and position the bear­
ing cover over the shaft and against the pedestal
with the word “TOP” on the bearing cover at the 12
o'clock position. Secure the bearing cover to the
pedestal with the hardware (51 and 52).
Secure the pedestal to the base with the previously
removed hardware. Be sure to reinstall any leveling
shims used under the mounting feet.
Lubricate the bearings and pedestal as indicated
in LUBRICATION at the end of this section.
Reinstall any leveling shims used under the pedes­
tal mounting foot and use a hoist and the previ­
ously installed lifting eye to position the assembled
pedestal on the base. Secure the pedestal to the
base with the previously removed hardware (36, 37
and 38, Figure E-1).
Install the drive key (62) and the half of the coupling
(33, Figure E-1) on the shaft. Connect the coup­
ling halves and check the coupling alignment (see
Alignment in INSTALLATION).
Position the coupling guard (8, Figure E-1) over
the coupling and secure it to the base with the pre­
viously removed hardware (15, 16, 29, 30 and 35,
Figure E-1).
Use the hardware (29, 55 and 56) to secure the
bottle oiler bracket (54) to the pedestal (2).
Seal Reassembly and Installation
(Figures E-3 and E-4)
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.
Inspect the impeller shaft for damage. Small
scratches or nicks may be removed with a fine file
or emery cloth. If excessive wear exists, the shaft
will have to be replaced.
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 (30), or re­
place it if there are nicks or cuts on either end. If any
components 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, bellows and shaft sleeve with water or a very
small amount of oil, and apply a drop of light lubri­
cating oil on the finished faces. Assemble the seal
as follows, (see Figure E-4).
