Genuine Cummins NTA855-C310 Engine: Heavy-Duty 310HP Power for Global Industry
The Cummins NTA855-C310 engine is a heavy-duty 14L industrial diesel engine developed by Chongqing Cummins Engine Co., Ltd. (CCEC) for demanding construction, mining, and industrial power applications. As a professional engine supplier, HekoPower provides genuine Cummins NTA855-C310 engine assemblies for customers requiring stable performance, long service life, and reliable operation under continuous high-load conditions.
This model belongs to the Cummins NTA855 engine series and is widely recognised for its durability in severe working environments. The engine adopts a turbocharged and aftercooled air intake system combined with the reliable Cummins PT fuel system, enabling stable fuel delivery and efficient combustion even in dusty, high-temperature, or high-altitude operating conditions.
Compared with lighter-duty industrial engines, the NTA855-C310 is specifically designed for machinery requiring strong low-speed torque and long-duration operating capability. The engine is commonly used in bulldozers, drilling machines, mining equipment, cranes, concrete mixer trucks, and oil field machinery.
HekoPower supplies complete genuine engine units, including flywheel housing, fuel system, turbocharger, cooling components, and industrial configuration accessories according to customer requirements.

Technical Mastery: The Cummins PT Fuel System Advantage
One of the core reasons the NTA855-C310 engine assembly is preferred by engineers worldwide is the integration of the Cummins PT (Pressure-Time) fuel system.
Unlike modern common-rail systems that can be sensitive to fuel quality, the PT system is:
- Self-Adjusting: Automatically compensates for wear and varied fuel viscosity.
- High Pressure: Ensures complete atomization for low fuel consumption.
- Simple Maintenance: Features fewer moving parts, making it the ideal Cummins Euro I industrial engine for remote oil fields and mining sites where high-tech diagnostic tools are unavailable.
Specific Applications: From Shantui Bulldozers to Oil Field Rigs
To avoid the homogenization seen on competitor sites, it is vital to understand where the NTA855-C310 construction engine excels.
Construction and Earthmoving
The most common application is the NTA855-C310 engine assembly for Shantui SD22 bulldozers. The engine’s torque curve is specifically matched to the hydraulic demands of heavy blade pushing. It is also a frequent choice for heavy-duty cranes, loaders, and road rollers.
Mining and Oil Field Machinery
In the energy sector, this heavy duty industrial diesel engine powers drilling machines and oil field machinery. Its ability to operate at extreme temperatures and high altitudes without significant power derating makes it a "workhorse" for the global extraction industry.
Why Source Your NTA855-C310 from HekoPower?
As a genuine Chongqing Cummins engine exporter, HekoPower bridges the gap between the factory and the end-user.
Quality Assurance and Warranty
"Where to buy genuine CCEC NTA855-C310 with warranty?" is a common question for procurement officers. HekoPower offers full factory-backed warranties, ensuring that every genuine engine unit is tested on the dynamometer before it leaves the facility.
Export Logistics: Shipping Weight and Dimensions
For international buyers, calculating landed costs is critical. The NTA855-C310 engine export shipping weight is approximately 1,300kg (dry), with dimensions typically reaching 1,500mm x 1,000mm x 1,300mm. We provide professional seaworthy wooden crate packaging to ensure your industrial power pack arrives in pristine condition.

Maintenance Tips for Longevity
To ensure your Cummins 14L construction diesel engine lasts for its intended 20,000+ hour lifecycle, consider these factors:
- Filter Intervals: Always use genuine Fleetguard filters to protect the PT fuel system.
- Coolant Chemistry: Maintain the correct SCA (Supplemental Coolant Additive) levels to prevent liner pitting.
- Oil Quality: Use high-grade lubricating oil specifically designed for heavy-duty industrial diesel engines.
