Make certain shims,when incorporated, are reinstalled when unitis assembled.(g)Remove nut (85) and lockwasher (86).(h)Use a puller to remove the bearing from theshaft. (See figure 11-15.) Protect the shaftend with a cap. If bearing is to be usedagain, make sure puller applies pressureonly against the bearing inner ring.(1) Bearing Inspection. The following inspection ofthe bearing should be made: Results of theinspection will determine if the bearing is to bereplaced.(a) Wash the bearing and inspect the residue.If hips and flakes are found, replace thebearing.(b)Observe the outer diameter of the bearingand the inner surface of the bearinghousing section of the endbell for evidenceof spinning.(c) Check the bearing for flaking or denting bygrasping the outer race and rotating slowingto feel for dented or flaked balls or races.Replace bearing if excessive roughness isfelt.(d) Examine the cage for wear. If a badcondition of smearing exists, remove thebearing from service.Figure 11-15. Removing Bearing from GeneratorShaft(e)Inspect the inner race. Examine the ball pathto see that it is smooth and free frombreaks. Dirt denting is not consideredserious if it is not concentrated.(f)Inspect the balls. Examine them visually todetermine if metal has flaked from thesurface. If flaking has occurred, remove thebearing from service. A small amount ofevenly distributed denting marks on the ballis usually not considered serious. Severalconcentrated denting marks is seriousenough to reject the bearing for furtherservice.(g)If there is a doubt that the bearing is notcompletely satisfactory, replace thebearing.(h) If the bearing is satisfactory, replace it twothirds full with grease (MIL-G, type23827AMI).(2) Replacement.(a)Heat the bearing to a11-26
