we have EGT make frame V, four nos gas turbine. in all the machines max vibration was seen at exciter end. recently, in Machine #2, the max vibration has shifted from exciter end to bearing #2 area. the value is steady at around 7 mm/sec and there is no visible sign of other problem.
can any one point out the real problem and suggest measures.
