stator and exciter stator as a unit.
NOTE
Tap lightly with rubber mallet to loosen
endbell. Check for shims in the endbell
bearing housing (well). Make certain shims,
when incorporated, are reinstalled when unit
is assembled.
(g)
Remove nut (85) and lockwasher (86).
(h)
Use a puller to remove the bearing from the
shaft. (See figure 11-15.) Protect the shaft
end with a cap. If bearing is to be used
again, make sure puller applies pressure
only against the bearing inner ring.
(1)
Bearing Inspection. The following inspection of
the bearing should be made: Results of the
inspection will determine if the bearing is to be
replaced.
(a)
Wash the bearing and inspect the residue.
If hips and flakes are found, replace the
bearing.
(b)
Observe the outer diameter of the bearing
and the inner surface of the bearing
housing section of the endbell for evidence
of spinning.
(c)
Check the bearing for flaking or denting by
grasping the outer race and rotating slowing
to feel for dented or flaked balls or races.
Replace bearing if excessive roughness is
felt.
(d) Examine the cage for wear. If a bad
condition of smearing exists, remove the
bearing from service.

Shaft
(e)
Inspect the inner race. Examine the ball path
to see that it is smooth and free from
breaks. Dirt denting is not considered
serious if it is not concentrated.
(f)
Inspect the balls. Examine them visually to
determine if metal has flaked from the
surface. If flaking has occurred, remove the
bearing from service. A small amount of
evenly distributed denting marks on the ball
is usually not considered serious. Several
concentrated denting marks is serious
enough to reject the bearing for further
service.
(g)
If there is a doubt that the bearing is not
completely satisfactory, replace the
bearing.
(h) If the bearing is satisfactory, replace it two
thirds full with grease (MIL-G, type
23827AMI).

Replacement.
(a)
Heat the bearing to a
