QSK23 mining engine overview
The Cummins QSK23 mining engine is a 23.15-litre inline-six with turbocharging and charge-air cooling. Current Cummins mining literature lists ratings from 760 to 1,050 hp depending on calibration and emissions configuration, and identifies the Modular Common Rail System as a key feature. Because variants and regional emissions packages differ, use the engine serial number and equipment build data when ordering service parts.
- Inline six-cylinder layout with 170 mm bore and stroke.
- Mining ratings and emissions equipment vary by market and engine build.
- Electronic and MCRS components require exact serial-number matching.
QSK23 spare parts supply scope
We quote QSK23 power-cylinder parts, bearings, gasket kits, turbochargers, cooling and lubrication pumps, sensors, injectors and common-rail fuel-system components. For electronic fuel parts, include the complete number from the removed unit and the engine serial number. A project list can combine mechanical and fuel-system items while keeping substitutions clearly identified.
- Pistons, liners, rings, bearings and gasket sets.
- Injectors, pumps, rail-system and electronic control components.
- Turbochargers, water pumps, oil pumps and related service parts.
QSK23 parts identification and quotation
Send the engine serial number, equipment model, existing part numbers, quantities and delivery location. If the request concerns a mining machine repower or a mixed overhaul kit, also include the QSK23 rating and emissions level. We will separate confirmed matches from alternatives so the final selection can be checked before shipment.
QSK23 ratings: mining engine and generator drive (G3 / G7)
Cummins builds the QSK23 in several application families, and the rating decides which turbocharger, fuel-system and control parts fit. The figures below come from Cummins specification sheets; confirm against the engine dataplate before ordering.
- Mining, EPA Tier 2: 760–950 hp (567–708 kW).
- QSK23-G3 generator drive, 1,800 rpm (60 Hz): 895 kWm standby / 809 kWm prime.
- QSK23-G3 generator drive, 1,500 rpm (50 Hz): 768 kWm standby / 701 kWm prime.
- QSK23-G7 generator drive (EPA Tier 2), 1,800 rpm: 910 kWm standby / 809 kWm prime.
- G-drive QSK23 engines use the HPI-PT fuel system: order injectors and pumps by the number on the removed unit.
