This remanufactured Cummins 4BT3.9 series diesel engine delivers 120 horsepower at 2300 RPM with a peak torque of 475 Nm at 1500 RPM, designed as a direct replacement for excavators and diesel generator sets. The engine features a 3.9-liter displacement with 4 cylinders in line, turbocharged and intercooled for improved fuel efficiency and performance. It meets NS II emissions standards, making it compliant for markets requiring this certification tier.
The engine block is cast iron with an aluminum cylinder head, steel crankshaft, and copper windings, ensuring durability under heavy-duty conditions. The 4BT3.9 series is known in the industry for its robustness in construction and agricultural machinery, with typical compression ratios of 16.5:1 for this displacement class. Standard fuel consumption for this power range is approximately 220-240 g/kWh, depending on load and operating conditions.
This unit is suited for buyers sourcing powerplant components for excavators, loaders, or generator sets, particularly in markets where NS II compliance is mandatory. The remanufacturing process restores the engine to original performance specifications, with typical warranty coverage of 12 months or 2000 operating hours, whichever comes first. Buyers should confirm compatibility with their equipment’s mounting points and electrical interfaces, as variants exist for different applications.

Before ordering, verify the engine’s exact model code and variant (e.g., 4BTA3.9-C125-II) to ensure compatibility with your equipment’s mounting and electrical systems. Request the supplier’s remanufacturing process documentation, including component replacement lists and testing procedures, to assess quality. Check if the engine includes peripherals like the turbocharger, fuel pump, and injectors, or if these are sold separately.
Confirm logistics details such as the shipping port (likely Shanghai or Ningbo for Hubei-based suppliers), Incoterms (FOB or CIF are common for engine exports), and lead time, which can range from 15 to 30 days for remanufactured units. Payment terms often require a 30% deposit, with the balance due before shipment. Ensure the supplier can provide a commercial invoice and packing list that meet your country’s import documentation requirements.
Inspect the engine upon arrival for signs of proper remanufacturing, such as clean cylinder bores, verified compression tests, and absence of oil leaks. Request a third-party inspection report if the supplier does not provide one. For emissions compliance, confirm that the engine’s NS II certification is documented and valid for your market. Store the engine in a dry, temperature-controlled environment if not installed immediately to prevent corrosion or seal degradation.
