MAINTENANCE & REPAIR PAGE E − 6
Remove the slinger ring (16) 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 (9) from the pedestal bore. Remove the
bearing shims (13). For ease of reassembly, tie and
tag the shims or measure and record their thick-
ness.
Place a block of wood against the impeller end of
the shaft and tap the shaft and assembled bear-
ings (12 and 15) out of the pedestal.
It is not necessary to remove the inboard retaining
ring (7) unless replacement is required. Use snap
ring pliers to remove the bearing retaining ring from
the pedestal bore.
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-
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 pedestal.
Replace the bearings, shaft, or pedestal if the
proper bearing fit is not achieved.
If bearing replacement is required, use a bearing
puller to remove the bearings from the impeller
shaft.
Shaft And Bearing Reassembly And Installation
Clean and inspect the bearings as indicated in
Shaft and Bearing Removal and Disassembly.
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.
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 and
bearings are removed.
