Are you looking for a compact, Tier 4-compliant used engine for your mini excavator or compact tractor? This fully rebuilt Yanmar 3TNV74F diesel engine delivers clean, reliable power for the most demanding small equipment applications. This engine meets EU Stage V and EPA Tier IV Final emission standards.

The 3TNV74F is a 0.993-liter, naturally aspirated, 3-cylinder, 4-cycle, water‑cooled diesel engine with an indirect injection fuel system. We have completely overhauled this used engine for sale to restore its original factory performance. It gives you a cost‑effective way to keep your compact equipment working while meeting modern emission requirements.

Advanced Clean Diesel Technology

The 3TNV74F engine meets the strict NTE and NRTC test requirements for EPA Final Tier 4 and EU Stage V. It uses common rail direct‑injection, exhaust gas recirculation, and a diesel particulate filter to achieve its clean emission levels. Yanmar has refined the combustion process through an advanced ECU to assure more precise fuel delivery and control. Compared to previous designs, this engine runs with greatly reduced fuel consumption, less vibration, and near‑elimination of white smoke.

Key Features

Meets Global Emission Standards: The 3TNV74F meets EPA Final Tier 4 and EU Stage V emission standards. This makes it a good choice for job sites and regions with strict emission rules.
Reliable Indirect Injection Design: This engine uses an indirect injection (IDI) combustion system. IDI technology is known for its durability, excellent cold starting performance, smooth operation, and low fuel consumption under typical variable speed operation.
Durable and Compact Package: With a dry weight of just 103 kg and compact dimensions, the 3TNV74F fits easily into tight engine compartments such as 1.5 to 2.0 ton mini excavators and compact tractors. Yanmar ensures high-strength materials and precise manufacturing for OEM reliability.
Proven Reliability in Global Equipment: The 3TNV74F engine is widely used by major global equipment brands. It is found in Yanmar, Wacker Neuson, Sany, John Deere, Bobcat, Caterpillar, and Takeuchi mini excavators. Many of these engines run for thousands of hours with good maintenance.
Quiet and Clean Operation: The refined combustion process, combined with the DPF, reduces emissions, improves performance, and greatly reduces smoke, particularly during cold starts and idle.
Fully Rebuilt to OEM Standards: We completely disassemble each engine and rebuild it to original Yanmar factory specifications. We recondition the cylinder head and inspect the cylinder block. We service the fuel injection system, and all critical wear parts are replaced with new components.
Tested Before Shipping: Every unit is hot‑run tested to verify compression, oil pressure, cooling performance, and injection timing. A test report is available upon request.
Ready for Installation: This used engine for sale ships as a complete long block assembly with pre‑installed filters and fluids. Necessary mounting hardware and wiring harness are included for straightforward installation.
