I would like your professional opinion on this problem that we had a couple of weeks ago. We were carrying out Off-Line Compressor Water Wash, when the turbine couldn’t break away, even though the unit was in crank mode and the starting motor was running. Subsequently, several attempts to put the unit on crank mode proved futile. The torque converter guide vane angle, which was originally 68 degrees was increased, but still the starting motor was unable to break the turbine away, even though the input shaft of the torque converter was turning, the output shaft was not turning. The adjuster motor and transmitter feedback were tested and they were working okay. The fill/drain solenoid, 20TU_1 and its limit switch, 33TC_1 were both working well. It seemed as though there was no problem with the torque converter and that, it was the gas turbine shaft that had all of a sudden gained more weight and therefore, the inability of the starting motor and torque converter to turn it. This situation was resolved only after we manually turned the gas turbine shaft, with the help of a jig, two revolutions. The shaft finally broke away with the same torque converter guide vane angle of 68 degrees. Have you experienced this problem before and what is the root-cause of it?
