When it comes to heavy machinery, engine replacements are a significant task that can extend the lifespan of equipment. For compact excavators like the Yanmar VIO35-2, engine swaps can be tricky, but with the right approach, they can be incredibly rewarding. In this article, we’ll dive into the specifics of swapping the 3TNE82A engine for the 3TNV82A-GG in a Yanmar VIO35-2, exploring the process, challenges, and best practices for a successful engine swap.
Overview of the Yanmar VIO35-2
The Yanmar VIO35-2 is a compact excavator known for its versatility and performance in confined spaces. It is often used in urban construction, landscaping, and other projects where space is limited. Powered by a small, reliable diesel engine, the VIO35-2 provides both power and efficiency, which is critical for small excavation jobs.
Like all machines, after extended use, components of the Yanmar VIO35-2 will inevitably wear down. The engine is one of the most crucial parts of the machine, and when it starts to fail, replacing it can be a practical solution rather than facing the costs and hassles of frequent repairs.
Understanding the Engine Swap: 3TNE82A vs. 3TNV82A-GG
The Yanmar VIO35-2 originally comes with the 3TNE82A engine. Over time, operators might find that replacing the engine is necessary for improved performance or to replace a damaged unit. In this case, the swap involves replacing the 3TNE82A with the more modern 3TNV82A-GG engine.

Challenges When Swapping the Engines
Swapping engines in heavy equipment can be complex, and in the case of the Yanmar VIO35-2, several challenges may arise. These include compatibility issues, electrical connections, and ensuring the new engine operates optimally within the existing machine setup.
1. Compatibility of Mounting Points
While the 3TNE82A and 3TNV82A-GG are both three-cylinder engines, their mounting points may not perfectly align with each other. This means that some adjustments to the engine cradle or frame may be necessary to ensure a proper fit.
Solution:
Before proceeding with the swap, carefully measure and compare the engine mounts for both engines. If needed, fabricate new mounts or modify the existing ones to accommodate the new engine securely.
2. Electrical and Wiring Differences
With an engine swap, the electrical connections may differ. This includes issues with the wiring harness, sensor placements, and the fuel system, which can have different configurations between the two engines.
Solution:
You will likely need to either modify or completely replace the wiring harness to make it compatible with the 3TNV82A-GG engine. It’s crucial to review the wiring diagram for both engines and ensure that all sensors, injectors, and other components are properly connected.
3. Fuel System Modifications
One of the more complicated aspects of engine swaps is dealing with the fuel system. The 3TNE82A and 3TNV82A-GG may have different fuel injection systems or pump configurations, which means that modifications could be required.
Solution:
Examine the fuel injection system on the 3TNE82A, and compare it with the 3TNV82A-GG. You may need to replace the fuel lines, injectors, and fuel pump to ensure that the new engine receives the proper fuel flow.
4. Exhaust and Cooling System Differences
Another issue could involve the exhaust system and cooling system. Differences in the exhaust manifold and cooling connections may require adjustments or the use of parts from the original engine.
Solution:
Inspect the exhaust manifold, radiator, and coolant hoses for compatibility. Custom modifications might be necessary to ensure that the exhaust gases are properly routed and the cooling system can effectively handle the new engine's output.
Steps for a Successful Engine Swap
With the challenges identified, the next step is to outline the best practices for swapping the engines.
Step 1: Preparation
When swapping engines in heavy equipment like the Yanmar VIO35-2, several considerations should be kept in mind:
Engine swaps in heavy machinery like the Yanmar VIO35-2 are no small task, but with proper planning and execution, they can greatly extend the lifespan of your equipment. The transition from the 3TNE82A to the 3TNV82A-GG engine offers improvements in fuel efficiency and performance, making it a worthwhile upgrade for many operators.
By understanding the challenges involved—such as compatibility issues, electrical connections, and fuel system modifications—you can ensure a smooth engine swap. Regular maintenance and careful installation will ensure that your Yanmar VIO35-2 continues to perform reliably for years to come.
