rings, stationary washers, seal spring and shaft
sleeve from the seal plate.
Inspect the seal liner (72) for wear or grooves
which could cause leakage or damage to the seal
packing rings. The seal liner is a press fit in the seal
plate and does not normally require replacement.
If seal liner replacement is required, refer to Seal
Reassembly and Installation.
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 pedestal drain plug (17) and drain the
pedestal (8). Clean and reinstall the plug.
Remove the slinger ring (22) from the shaft. Re­
move the pedestal mounting hardware from the
base. Tie and tag any shims used under the
mounting feet for leveling.
Use snap ring pliers to remove the bearing retain­
ing ring (11) from the pedestal bore. Remove the
bearing shim set (10); tie and tag the shims, or
measure and record their thickness for ease of
reassembly.
Loosen the machine screws (77) in the bearing re­
tainer (15). Pry the bearing retainer from the pedes­
tal bore using two screwdrivers against the heads
of the machine screws.
Press the oil seal (14) from the bearing retainer,
and remove the O‐ring (16) from the pedestal bore.
Place a block of wood against the impeller end of
the shaft and tap the shaft and assembled bear­
ings (5 and 9) out of the pedestal.
Remove the hardware (20 and 21) and remove the
the assembled bearing cap (4) and oil seal (18).
Press the oil seal from the bearing cap.
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.
Inspect the shaft for distortion, nicks or scratches,
or thread damage on the impeller end. Dress small
nicks and burrs with a fine file or emery cloth. Re­
place the shaft if defective.
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
races and cause premature bearing fail­
ure.
Rotate the bearings by hand to check for rough­
ness or binding and inspect the bearing balls. If ro­
