MAINTENANCE & REPAIR PAGE E − 10
Inspect the seal liner (74) 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 replacement is necessary, see Seal Reas-
sembly And Installation.
If no further disassembly is required, refer to Seal
Reassembly And Installation.
Shaft and Bearing Removal and Disassembly
(Figure E−2)
When the pump is properly operated and main-
tained, the intermediate should not require disas-
sembly. 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 intermediate drain plug (32) and drain
the lubricant. Clean and reinstall the drain plug.
Disengage the hardware (22 and 23) and remove
the bearing cap (21), gasket (20), oil seal (24) and
bearing shim set (27). Tie and tag the shims, or
measure and record their thickness for ease of rea-
ssembly.
Press the oil seal from the bearing cap.
Place a block of wood against the impeller end of
the shaft (26), and tap the shaft and assembled
bearings (18 and 29) from the intermediate. Press
the inboard oil seal (33) from the intermediate.
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 intermediate, shaft and all component
parts (except the bearings) with a soft cloth soaked
in cleaning solvent. Inspect the parts for wear or
damage 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
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-
tation is rough or the bearing balls are discolored,
replace the bearings.
The bearing tolerances provide a tight press fit
onto the shaft and a snug slip fit into the intermedi-
ate. Replace the bearings, shaft or intermediate if
the proper bearing fit is not achieved.
If bearing replacement is required, use a bearing
puller to remove the bearings from the shaft.

Inspect the shaft for distortion, nicks or scratches,
or for thread damage on the impeller end. Dress
