Restoring heavy equipment is no small task, but for enthusiasts and professionals alike, it can be an immensely satisfying journey. In this article, we explore the journey of a Volvo EW140, a wheel excavator, undergoing a "Make It Run" project. We'll look at the challenges, the process of restoring a piece of machinery, and the lessons learned along the way.
The Volvo EW140: A Classic Piece of Equipment
The Volvo EW140 is a compact yet powerful wheel excavator, commonly used in construction, landscaping, and urban infrastructure projects. Its versatility, combined with its ability to work on rough terrain, makes it a favorite among many operators. However, like all heavy machinery, it requires regular maintenance and occasional overhauls to maintain peak performance.
For many, acquiring older models of such machines at a reasonable price can offer an exciting opportunity to bring them back to life and make them operational again. The Volvo EW140, despite its age, is a solid machine, but it requires careful attention to various systems, including the engine, hydraulics, and electrical components, to ensure it runs smoothly once again.
The Initial Challenges: A Machine That Won't Start
The project begins with a common challenge many equipment owners face – a machine that just won’t start. Whether due to age, lack of maintenance, or unforeseen issues, equipment can sometimes sit idle for extended periods, leading to rust, fuel system issues, or electrical failures.
In the case of the Volvo EW140, the engine was not starting, and there was a strong suspicion that several components had gone out of alignment or become corroded. The first step in any restoration project is to perform a thorough inspection. It's essential to check the basic systems: fuel lines, battery connections, and electrical systems to ensure there's no obvious failure that could be easily repaired.
Step 1: Diagnosing the Fuel System
The fuel system is one of the first places to check when a machine won't start. Over time, old fuel can clog filters and injectors, especially if the machine has been sitting unused for a long period. In the case of the Volvo EW140, it was discovered that the fuel system was clogged, and the fuel lines had built up residue from old diesel.
The team began by draining the old fuel, replacing the fuel filters, and cleaning the fuel lines. They also checked the injectors to make sure they were operating properly. A simple fix, but one that required careful attention to detail, ensuring that no residue or blockages remained that could prevent the fuel from reaching the engine.
Step 2: Overhauling the Electrical System
Electrical issues are another common problem for machines that have been sitting idle. Wires can become brittle, connections can corrode, and sensors can malfunction. The EW140 wasn’t starting, in part, due to electrical issues with the battery connections and the wiring leading to the ignition system.
The restoration crew focused on cleaning and reattaching the battery terminals, checking for any worn-out cables, and ensuring that power was reaching all the necessary components. In many cases, simply replacing corroded cables and connectors can bring a machine back to life.
Step 3: Inspecting and Replacing Hydraulic Components
Hydraulics are often the most expensive components to repair or replace in heavy machinery. The Volvo EW140’s hydraulic system is what powers its boom, arm, and other critical functions. The restoration team paid close attention to the hydraulic fluid levels, ensuring that they were filled to the correct levels and that the fluid was clean and free of contaminants.
Next, the crew inspected the hoses and valves for leaks or damage. If a leak is detected in a hydraulic line, it’s crucial to repair or replace it as soon as possible to avoid system failure. In the case of the EW140, a few minor leaks were found and fixed, ensuring the machine would operate with optimal hydraulic pressure.
Step 4: Engine Repair and Maintenance
Once the electrical and hydraulic systems were addressed, the team turned to the engine. As with most restoration projects, an old engine requires a thorough examination. The engine was inspected for any signs of wear, such as oil leaks, degraded seals, or cracked hoses. A few minor repairs were needed, including the replacement of worn-out seals and gaskets.
The team also gave the engine a complete oil change and replaced the air filters. A fresh start for the engine was vital in ensuring it would run efficiently once powered up.
Step 5: Testing and Fine-Tuning
After performing these repairs, it was time to start the machine and test its functionality. The team turned the key and, after a few moments of anxious waiting, the engine roared to life. The hydraulic system worked as expected, and all the other systems functioned smoothly.
However, restoring machinery is rarely a “one and done” project. Minor tweaks and fine-tuning are often needed to perfect the machine’s performance. The team adjusted the throttle, checked for any leaks, and ensured that all components were functioning at full capacity.
Lessons Learned: The Importance of Preventive Maintenance
One of the key takeaways from any restoration project is the importance of preventive maintenance. A major reason this Volvo EW140 ended up in need of restoration was a lack of regular upkeep. Machines that are left without attention for long periods can deteriorate rapidly, especially when left exposed to the elements.
Preventive maintenance not only extends the life of your equipment but can also save you money by identifying small issues before they turn into major problems. Regular inspections, fluid checks, and system cleanings can help keep equipment running smoothly for many years.
Restoration Success: Bringing New Life to the Volvo EW140
In the end, the Volvo EW140 was successfully restored and made operational once again. The machine, which had been sitting idle for a while, was now ready to get back to work, performing tasks with efficiency and reliability.
This restoration project is a testament to the dedication and knowledge that equipment owners and mechanics bring to the table. With patience, careful inspection, and the right repairs, older machinery can be restored to its former glory and continue to serve in the field for many more years.
The story of the Volvo EW140 serves as a reminder that heavy equipment is built to last, and with the right care, even older models can offer exceptional value. For anyone considering a similar restoration project, the key is to approach it methodically, ensure all systems are checked, and don’t rush the process.
Whether you’re a seasoned mechanic or a newcomer to equipment restoration, there’s a sense of pride in bringing machinery back to life, and in doing so, you’re preserving a valuable tool for future use.
