Bearings
Inspect





1. NOTE: If any of the following conditions exist, install a new bearing.

Inspect the bearing for bent cage.





2. Inspect the bearings for galling (metal smears on the roller ends).
^ Galling is caused by overheat, poor lubrication, or overload.
^ If galling is found, install a new bearing and inspect the seals.





3. Inspect the bearing for brinelling (surface indentations in the raceway).





4. Inspect the bearing for cracked inner race.





5. Inspect the bearing and raceway for etching.
^ If etching is present, inspect the seals.





6. Inspect the bearing for heat discoloration (dark blue).
^ If heat discoloration is evident, check the bearing and race for loss of temper. Draw a file across the component. If the file cuts the metal, there is a loss of temper.





7. Inspect the bearing for fatigue spelling (metal flaking).
