The manual’s "Vibration Decision Tree" pointed to a non-original oil filter causing low oil temperature (80°F vs. spec 105°F). By swapping the filter and using an oil heater before startup, the vibration dropped to 1.1 mils. The manual paid for itself 100x over in avoided downtime. ge gas turbine frame 5 manual
