Observation
Harmonics of 9.32x running speed with 1x sidebands were detected, indicating a potential bearing defect. This occurred shortly after a recent bearing replacement, with continued vibration on the ODE side. Resolution: The full wheel assembly was replaced, and vibration levels have since decreased.
Recommendation
The CME recommended planning to replace the ODE bearing again, as the DE bearing vibration dropped after replacement, suggesting the issue may be isolated to the ODE.
Resolution
The full wheel assembly was replaced, and vibration levels have since decreased.
