3. Install the snap ring (#4) in
the pump end of the pedestal. Be
sure the snap ring is seated properly
in the groove. The beveled edge of
the ring should face away from the
bearing.

1. Stand a piece of 3/4" pipe,
with the threads cut off, on a work-

bearing placed on the correct shaft
end.
2. Insert the shaft into the pipe so the
bearing is between the pipe and the
shoulder of the shaft. Refer to Figure
5-9.
3. Using extreme caution, gently tap on
the end of the shaft until the bearing
rests against the shoulder. Never
attempt to install the bearings by
striking the outer race.
4. Repeat step 3 for the other bearing.

This procedure is not recommended and
should only be used in an emergency
situation.
5E Testing and Final Adjustments
1. Check to be sure that the
rotating assembly turns freely. Turn
the shaft by hand. If it is tight or
rough spots are encountered, it is
likely that at least one of the bearings
was damaged during disassembly/
assembly operations and will have to
be replaced.
2. Look to make sure that the lip seals
on the bearings are positioned
properly in their grooves. Correct
if necessary. As the bearings are
turned, the grooves should
appear wet with oil but have no vis-
ible grease present.
3. Recheck the snap ring on
the large bearing end. It should be

should result from gentle tapping
on either end of the shaft. (Use a
soft mallet so shaft surfaces are not
damaged.)
4. No adjustments are possible or
required. Proceed with the appropri-
ate pump end assembly operations.
Refer to Section 5 SERVICE - PUMP
ENDS (Final testing is
done after
the pump end is in place.)
