What This Engine Is Built For
Cummins M11-C310: a 6-cylinder in-line construction diesel engine displacing 10.8 L on a 125 * 147 mm bore and stroke, supplied complete by MEP Power. It is rated at 228 kW (310 HP) at 2100 rpm and develops 1424 N.m @ 1300 rpm. The engine is turbocharged-intercooled and water cooled, with a Direct Injection PT Pump, STC fuel system. It is built at the Chongqing Cummins Plant and carries Tier 1. Typical duty is excavators, wheel loaders, cranes, drill rigs and other off-highway machines; dry weight with flywheel and alternator is 980 Kg and the overall envelope is 1450mm*950mm*1010mm.
Key Benefits
- Delivers 228 kW (310 HP) at 2100 rpm from 10.8 L as a factory-rated assembly.
- Peak torque of 1424 N.m @ 1300 rpm holds the load without downshifting or derating.
- Turbocharged-Intercooled induction with water cooling keeps charge temperature under control in continuous duty.
- Supplied to Tier 1, so the unit can be registered in markets that require it.
- Dry weight 980 Kg and envelope 1450mm*950mm*1010mm are published so the installation can be checked before ordering.
- Rated for continuous running up to 3048 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 M11-C310 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

Use and Installation Guide
- Quote the model M11-C310 and the engine configuration number D353005CX03 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 228 kW (310 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine. |
| A larger engine in the same M11 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. |
