What the QSK19 Covers
The QSK19 and its mechanical predecessor the KTA19 are 19-litre inline-six engines. They are workhorses of marine propulsion, mining equipment, generator sets, and oilfield pumps — applications where an engine can run thousands of hours between major services and parts are ordered against an overhaul plan rather than a single failure.
Common Applications
- Marine propulsion and auxiliary power
- Mining trucks, loaders, and drills
- Prime and standby generator sets
- Oilfield pumps and industrial power units
Commonly Requested Parts
- Injectors, injection pumps, and fuel-line components
- Liner, piston, and ring kits, including oversize grades
- Connecting-rod and main bearings
- Turbocharger assemblies and aftercooler cores
- Heat exchangers and seawater-side components for marine units
- Starter motors, alternators, and mounting hardware
Overhaul Planning for K-Series Engines
For a planned overhaul, send the engine serial number, running hours, and the measurement records for liners, pistons, and bearings. Size-graded parts are confirmed after the engine is opened, so we usually quote firm lines for the items always replaced and provisional lines for the graded items. This avoids both shortages and parts that arrive in the wrong size.
Verification
KTA19 and QSK19 engines exist in mechanical and electronic generations with different fuel systems. The dataplate ESN and CPL decide the correct injector, pump, and sensor references. For marine units, include the gearbox and installation details when the part affects the driveline.
