Manual Transmission/Transaxle: Testing and Inspection

Bearing Inspection





1. Inspect the bearing for bent cage.

Note:
- If any of the following conditions exist, replace the bearing.





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





3. Inspect the bearing for surface indentations in the race.





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 spalling (metal flaking).
