What This Engine Is Built For
MEP Power supplies the Cummins C700 as a complete 6-cylinder in-line construction diesel engine of 19 L running a 159 * 159 mm bore and stroke. It is rated at 522 kW (700 HP) at 2000 rpm and develops 2730 N.m @ 2000 rpm. The engine is turbocharged-intercooled and water cooled, with a Direct Injection PT Pump fuel system. It is built at the Chongqing Cummins Plant QSKTAA19-C700 and carries Euro II. Typical duty is excavators, wheel loaders, cranes, drill rigs and other off-highway machines; dry weight with flywheel and alternator is 1699 Kg and the overall envelope is 2150mm*966mm*1704mm.
Key Benefits
- Delivers 522 kW (700 HP) at 2000 rpm from 19 L as a factory-rated assembly.
- Peak torque of 2730 N.m @ 2000 rpm holds the load without downshifting or derating.
- Turbocharged-Intercooled induction with water cooling keeps charge temperature under control in continuous duty.
- Supplied to Euro II, so the unit can be registered in markets that require it.
- Dry weight 1699 Kg and envelope 2150mm*966mm*1704mm are published so the installation can be checked before ordering.
- Rated for continuous running up to 2000 m altitude.
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 C700 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

Use and Installation Guide
- Quote the model C700 and the engine configuration number D193027CX02 when ordering so the correct variant is supplied.
- 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.
Customisation Options
- OEM and ODM builds, including your logo and company name on the unit
- Cummins engine customisation and modification to your requirement
- Mining and special explosion-proof builds
- Genuine or OEM parts specified on the quotation
How It Compares
| Compared with | What to consider |
|---|---|
| A rebuilt or used engine of the same rating | A rebuilt unit may show the same 522 kW (700 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same KTAA19 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. |
