As with the previous case, when the good motors were put in the third location, the 120 HZ vibration was high. A resonance test was performed and it was discovered that where the vibration levels were high that the foundation had a 120Hz vertical resonance that was not present under the other two motors. When the foundation under the bad location was jack hammered out, it was discovered that [...]
