MAINTENANCE & REPAIR PAGE E − 18
The balance ring must seat squarely in the
pump casing; otherwise binding and/or
excessive wear will result.
Install the casing gasket (8) over the studs (33).
Position the pump casing over the shaft and
against the intermediate. Secure the casing to the
intermediate with the hardware (34 and 35).
Install any leveling shims used under the pump
casing mounting feet and secure the pump casing
to the base with the previously removed mounting
hardware.
Seal Reassembly and Installation
(Figures 4 and 9)
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 badly worn. 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 sta-
tionary seat O-ring, bellows 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 follows, (see Figure 9).
