This Technical Service Bulletin introduces new lower engine gasket sets which can be purchased for smaller repairs.
Currently, there is a lower gasket set for the QSK60, Part Number4089148, and a lower gasket set for the QSK45, Part Number 4066323. These are large sets with many different o-rings, seals, and hoses. The new gaskets sets are divided into specific functions on the engine.

All QSK60 and QSK45 Power Generation and Industrial engines will be affected by this change.
