MAINTENANCE & REPAIR

strongly
recommended that the bearings
be replaced
any
time the shaft and bear
ings are removed.
Clean the bearing housing, shaft and all compo
nent 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 bearing
housing. Replace the bearings, shaft, or bearing
housing if the proper bearing fit is not achieved.
If bearing replacement is required, remove the out
board bearing retaining ring (20). Use a bearing
puller to remove the bearings from the shaft.
Shaft and Bearing Reassembly and Installation
(Figure 2)
Clean the bearing housing, shaft and all compo
nent parts (except the bearings) with a soft cloth
soaked in cleaning solvent. Inspect the parts for
wear or damage 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.
NOTE
There is a 1‐1/2 inch diameter socket head pipe
plug (28) located in the side of the bearing housing.
The hole is required for manufacturing purposes
only; therefore the pipe plug should never require
removal.
Inspect the shaft for distortion, nicks or scratches,
or for thread damage on the impeller end. Dress
small nicks and burrs with a fine file or emery cloth.
Replace the shaft if defective.
Position the inboard oil seal (6) in the bearing hous
ing bore with the lip positioned as shown in Figure
2, Detail C. Press the oil seal into the housing until
the face is
just flush
with the counterbored surface
toward the inside of the housing.
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.
NOTE
Position the outboard bearing (21) on the shaft with
the integral retaining ring on the bearing O.D. to
ward the drive end of the shaft.
