Recently after completion of major inspection & rotor inspection (Integration) on GE 9171E gas turbine, during start up bearing #1 vibration exceeded from 25.4 mm/s at about 1200 RPM.
Bearing #1 and #2 have been changed and also two sections of the IGV ring gear. We have checked lube oil temperature and gas control valve calibration.
Would any one help up ASAP? Any solution is a great pleasure to us.
