Seal Removal and Disassembly
Remove the spring centering washer (59) and the
seal spring. Slide the shaft sleeve (33) and rotating
portion of the seal off the shaft as a single unit. Ap­
ply oil to the sleeve and work it up under the bel­
lows. Slide the rotating portion of the seal off the
shaft.
Slide the seal plate and seal assembly off the shaft
as a single unit. Place the seal plate on a flat sur­
face with the impeller side down. Use a suitably
sized dowel to press the seal components from the
seal plate.
Pry or press the oil seal (14) from the seal plate. In­
spect the seal plate and replace it if cracked or
badly worn.
If no further disassembly is required, see Seal
Reassembly and Installation.
Shaft and Bearing Removal and Disassembly
When the pump is properly operated and main­
tained, the pedestal should not require disassem­
bly. Disassemble the shaft and bearings only
when there is evidence of wear or damage.
Shaft and bearing disassembly in the field
is not recommended. These operations
should be performed only in a properly‐
equipped shop by qualified personnel.
Remove the slinger ring (31) and shaft key (26).
Disengage the hardware (23 and 24) and remove
the pedestal foot (29). Slide the bearing cap (25)
and oil seal (28) off the shaft.
NOTE
There are no provisions for draining the lubricant
from the pedestal. Place a drip pan under the ped­
estal before disassembly.
Use an arbor (or hydraulic) press and a dowel to
remove the oil seal from the bearing cap.
Slide the bearing shims (21) off the impeller shaft.
Tie and tag the shims or measure and record their
thickness for ease of reassembly.
Place a block of wood against the impeller end of
the shaft and tap the shaft and assembled bear­
ings (17 and 30) from the pedestal. Be careful not
to damage the shaft.
After removing the shaft and bearings, clean and
inspect the bearings in place as follows.
To prevent damage during removal from
the shaft, it is recommended that bearings
be cleaned and inspected in place. It is
strongly recommended that the bearings
be replaced any time the shaft and bear­
ings are removed.
Clean the pedestal, shaft and all component parts
(except the bearings) with a soft cloth soaked in
cleaning solvent. Inspect the parts for wear or dam­
age and replace as necessary.
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.
Clean the bearings thoroughly in fresh cleaning
solvent. Dry the bearings with filtered compressed
air and coat with light oil.
Bearings must be kept free of all dirt and
foreign material. Failure to do so will great­
ly shorten bearing life. Do not spin dry
bearings. This may scratch the balls or
