MAINTENANCE AND REPAIR

will result in premature leakage or reduced pump
performance. It is strongly recommended that new
gaskets and shaft seal assemblies be used during
reassembly (see the parts lists for numbers).

It is

strongly recommended

that the intermediate

and rotor subassembly be removed from the motor
housing as a single unit to check the bearings for
proper positioning and to force all shaft end‐play in
one direction during pump end reassembly. Re
move the subassembly as described in

Motor Dis

assembly

.

Cleaning And Inspection Of Pump Parts

(Figure E-1)

With the pump inverted, stuff a clean tissue into the
stationary seal seat bore of the intermediate (17) or
wrap a small rag around the shaft to prevent for
eign material from entering the motor cavity.

Carefully inspect any O‐rings or gaskets before re
moval and cleaning to determine if a proper seal
and compression existed prior to disassembly. If
sealing was faulty or questionable, the cause must
be determined and corrected before reassembly.
Replace any parts as required.

Thoroughly clean all reuseable parts with a soft
cloth soaked in cleaning solvent. Remove all O‐
rings and gaskets, and clean the sealing surfaces
of dirt or gasket material. Be careful not to scratch
gasket surfaces.

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 rotor shaft (23) for damaged threads,
scoring, or nicks. Remove nicks and burrs with a
fine file or hand honing stone to restore original
contours. If the shaft is bent or severely damaged,
the rotor and shaft must be replaced as an assem
bly (see

MOTOR DISASSEMBLY

).

Neither of the shaft seal assemblies (3 or 4) should
be reused because wear patterns on the finished
faces cannot be realigned during reassembly. This
could result in premature failure. If necessary to re
use an old seal in an

emergency

,

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 the preci
sion 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 circular pattern to avoid

scratching the faces.

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.

Install the shaft seals as illustrated in Figure E-3.
