Key Benefits
- Delivers 810 kW (1086 HP) at 1800 rpm Peak Torque/Speed: 4869 N.m @ 1350 rpm Engine from 37.7 L as a factory-rated assembly.
- Turbocharged Aftercooled induction keeps charge temperature under control in continuous duty.
- Supplied to U.S. EPA Tier 2, so the unit can be registered in markets that require it.
- Dry weight 4510 Kg and envelope N/A are published so the installation can be checked before ordering.
- Published fuel consumption of 214g/Kw.h @ 1800 rpm QSK38-C – Technical Specification Emission makes running cost predictable.
- Starts without auxiliary aids down to -12℃ Cooling System.
Application Scenarios
- 20-35 t excavator power unit replacement
- Wheel loader and grader repower
- Crawler crane and drill rig drive
- Concrete pump and batching plant drive
Who It Is For
- Excavator and loader rebuilders replacing a failed power unit
- Plant hire fleets that need machines back on rent quickly
- OEM machine builders sourcing a proven engine for a new chassis
- Quarry and earthmoving contractors running machines in dusty, high-load duty
Problems It Solves
- A machine down in the middle of a job stops the whole site, not just one asset.
- Rebuilt short blocks of unknown history fail again inside the warranty window.
- Dust, vibration and long hours at high load expose any weakness in the power unit.
- Identifying the right QSK38-C variant from a serial number takes experience; MEP Power checks the configuration before quoting.

- Confirm flywheel housing, SAE size and pump drive against the machine
- Transfer the machine's own wiring harness only after checking the connector layout
- Run the first 50 hours at moderate load before full-duty work
- Keep the warranty terms in mind: one year or 1000 hours, whichever comes first.

How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 810 kW (1086 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same QSK38 range | Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom. |
| A non-Cummins engine of similar output | Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one. |
