Cummins QSB5.9-C180-34 DCEC 180HP Diesel Engine

The Cummins QSB5.9-C180-34 is a 5.9L, inline 6-cylinder industrial diesel engine delivering 133 kW / 180 HP at 2,200 RPM and 770 N·m peak torque at 1,400 RPM. It is commonly used in mid-class construction machinery, including hydraulic excavators, wheel loaders, road machinery and other equipment that requires stable low-speed torque and reliable continuous operation.

Manufactured by Dongfeng Cummins Engine Co. (DCEC), the QSB5.9-C180-34 uses a BOSCH high-pressure common rail fuel system, ECM electronic control, turbocharged charge-air-cooled configuration and water cooling. It meets Tier 3 / EU Stage IIIA / China NS III emission standards for suitable international project and replacement applications.

For equipment owners facing engine failure, power loss or planned fleet maintenance, this model is often selected as a replacement engine after the original ESN, nameplate, CPL or machine configuration is confirmed. ZEB Power helps verify the correct engine configuration before quotation to reduce wrong-order risk and installation delay.

Typical Applications

The QSB5.9-C180-34 is suitable for equipment where mid-range power, hydraulic response and low-RPM torque are important for daily operation. It is commonly considered for replacement, fleet maintenance, OEM configuration matching and project stock supply.

• 20–25 ton hydraulic excavators
• 4–5 ton wheel loaders
• Medium construction machinery
• Road machinery and compactors
• Hydraulic working equipment
• Industrial utility equipment
• Replacement engines for existing QSB5.9 applications

Typical compatible equipment may include selected platforms from Sany, XCMG, Liugong, Lonking and similar OEM configurations. Final fitment must be confirmed by ESN, engine nameplate, original engine configuration and regional emission requirements.

Technical Specifications

Specifications may vary depending on the final engine configuration, production batch, starting voltage, emission configuration and destination market requirement. Please confirm ESN or engine nameplate before ordering.

QSB5.9 Series Comparison

The QSB5.9-C180-34 sits in the mid-high power range of the QSB5.9 platform. Its key feature is 770 N·m peak torque available at 1,400 RPM with 180 HP rated output at 2,200 RPM, making it suitable for hydraulic equipment where low-speed pulling power affects working efficiency.

If you are not sure which QSB5.9 variant matches your machine, please provide the existing engine serial number, nameplate photo or original engine model. The C180-31, C180-33 and C180-34 may have similar power ratings but different rated speeds, torque curves and application calibrations.

Replacement Compatibility and Fitment Verification

The QSB5.9-C180-34 can be considered for selected mid-class construction machinery originally configured with compatible QSB5.9 series engines. However, fitment varies by production year, regional emission specification, wiring harness, starting voltage and OEM build configuration.

Two machines with the same model name may use different engine variants depending on market, build date and emission zone. For this reason, matching by machine model alone is not recommended.

This verification process helps eliminate one of the main risks in engine procurement: ordering a unit that has the right power rating but cannot be installed or connected correctly.
