Cummins QSK60, QSK60 engine maintenance, QSK60 service schedule, QSK60 oil filter service, QSK60 overhaul interval
General Maintenance Principle
The Cummins QSK60 engine adopts a dual maintenance standard based on operating hours and calendar time. Service work shall be performed whichever interval comes first.
Once any maintenance interval is reached, all previous scheduled inspection and service items must be completed in full. Do not skip or simplify any maintenance procedures.
The QSK60 engine is available with six factory optional oil filtration systems. The service routine must follow the exact maintenance procedure corresponding to the actual filter configuration installed on the engine.

Important Notes
- Fuel injector replacement at 10000 hours applies only to electronically controlled injector engines. Mechanically actuated injector engines shall follow separate Cummins service instructions.
- Drainage procedures for alternative fuel filters can refer to the oil drain and fuel filter replacement sections of this guide.
- All engine oil sampling and analysis must strictly comply with the corresponding Cummins official technical bulletins to ensure engine reliability and service life.
