What the QSK50 Covers
The QSK50 and KTA50 are 50-litre V16 engines — the largest members of the Cummins K and QS families. They are found in the largest mining trucks, locomotives, big vessels, and multi-megawatt generator sets. Engines at this scale are usually supported by a planned maintenance program, and parts orders arrive as consolidated lists rather than single line items.
Common Applications
- Ultra-class mining haul trucks
- Locomotives and rail power
- Large marine propulsion installations
- Prime power and grid-support generator plants
Commonly Requested Parts
- Injectors, pumps, and high-pressure fuel components
- Liner, piston, and ring kits with size grades

- Turbochargers and charge-air components
- Oil pumps, coolers, and filtration components
- Sensors, wiring, and electronic-control parts
Working From an Overhaul List
Send the engine model, serial number, running hours, and your planned list in Excel or PDF. We confirm each line against the catalog history, identify superseded numbers, separate firm from measurement-dependent items, and quote with lead time and shipment weight per line. For parts still installed, a photo of the component label usually settles the reference faster than a description.
