The U. S. Navy uses the Allison 501-K series engines as the prime mover of the Ship Service Gas Turbine Generators (SSGTGs) on DD-963, DDG-993, CG-47 and DDG-51 Class Ships. Historical data shows the engine’s most unreliable component to be the Accessory GearBox (AGB). This paper describes an intensive effort to identify and correct the root cause of the AGB failures and improve overall engine reliability and operational availability.
