The Cummins QSK60 is a high-horsepower engine with a displacement of 60 liters; it ranks third in the Cummins lineup, surpassed in displacement only by the QSK78 and QSK95 models. Known for its stable and efficient performance, the QSK60 is primarily used in mining trucks (from manufacturers such as Komatsu, Belaz, XCMG, and SANY) and generator sets.
Basic Construction of the Cummins QSK60 Engine
From the structural diagram above, we can observe the key characteristics of the Cummins 60L engine:
- V-configuration with a 60-degree bank angle, featuring a total of 16 cylinders.
- Independent cylinder design; the engine utilizes 16 Cummins QSK60 cylinder heads.
- Twin-turbocharger and intercooler configuration.
How to service a Cummins QSK60 engine
A-Remove the external components of the QSK60 engine, and clean and inspect the core components.
B-Determine the cause of the QSK60 engine fault (connect diagnostic equipment to the ECU and read the fault codes), then prepare the engine parts required for replacement.
The following table lists common fault codes for the QSK60 diesel engine along with an analysis of the issues; you can use this for reference.

C-Verify the part numbers and install the components into the QSK60 engine in accordance with Cummins assembly specifications; pay special attention to cleaning the parts and applying lubricant to them prior to installation.
D-Re-examine the installed QSK60 engine components to verify that overall operating performance is normal, then return all components to their proper positions.
The following are the installation torque requirements and precautions for servicing the QSK60 engine:
ITEM | Categoria | Component/Part | Torque (N·m) | Tightening requirements/Notes |
| 1 | Cylinder head bolts | Cylinder head (stretch bolts) | Pre-tighten to 300, then turn 90° | Torque-plus-angle method; tighten in stages using a diagonal pattern; check bolt free elongation |
| 2 | Main bearing cap bolts | Crankshaft main bearing cap | 50 → 200 → 420, then turn 90° | Tighten in three steps; proceed from the center outwards to both ends, tightening in stages using a diagonal pattern |
| Main bearing cap bolts | Main bearing side cover | 390 | ||
| 3 | Connecting rod bolts | Connecting rod cap | Pre-tighten to 200, then turn 90° | Torque-plus-angle method; connecting rods must be used as matched sets |
| 4 | Flywheel bolts | SAE No. 0 flywheel housing | 810 | Tighten in stages using a diagonal pattern |
| Flywheel housing bolts | M16 | 280 | ||
| 5 | Flywheel housing bolts | M12 | 165 | |
| 6 | Flywheel housing bolts | M10 | 80 | |

| 7 | Other assemblies | Turbocharger exhaust flange bolt | 68 | |
| 8 | Other assemblies | Oil filter base bolt | 105 | |
| Other assemblies | Water pump mounting bolt | 100 | ||
| 9 | Other assemblies | Thrust bearing cap bolt | 195 | |
| 10 | Performance output torque | Industrial/Mining version (depending on rating) | 8849–11257 | Maximum torque (at various speeds/calibrations) |
| Performance output torque | Marine engine QSK60-M | ≈10660 | Rated operating condition at 1800 rpm |
E-Inspect the assembled QSK60 engine, paying close attention to its power performance, as well as coolant temperature and oil pressure.
