A high-quality recycled engine that is more affordable than a new engine and environmentally friendly.

In recent years, instead of replacing diesel engines in large vehicles like trucks with new ones after a certain period, it has become increasingly common to revive them to like-new condition through regular maintenance and overhauls, allowing one engine to be used for a long time. An overhaul (OH) is an environmentally friendly method that involves disassembling an engine that has been used for many years and is starting to show operational issues, or one that has stopped working for some reason, down to the individual parts. It includes replacing and processing consumables and components, and then reassembling the engine to restore it to like-new condition. This process repairs the areas of friction to prevent air and oil intrusion or leakage, and cleans out sludge and carbon that have accumulated inside the engine due to long-term use or insufficient maintenance. Depending on the situation, parts that are malfunctioning, such as pistons and valves, can be replaced with new ones, allowing the engine to be revived with performance comparable to a new engine, enabling it to be used for a long time.

For example, please leave such cases to us. ◆ I want you to check the engine because there are issues (strange noises, problems during startup, power loss, etc.). ◆ I am looking for a company that can handle regular overhauls throughout the year. ◆ I want to request engine repairs in bulk, as I have several hundred cases a year. ◆ I want to repair a special engine, but I was turned away by other companies. ◆ I am looking for a partner to whom I can outsource just a part of the maintenance.

Applications/Examples of results

[Case Study] For a custom product from a special vehicle manufacturer, all engines are also of special shapes. The manufacturer suggested replacing the entire vehicle... Company A, a steel manufacturer, was using special vehicles to load massive steel materials produced at their factory onto transport ships docked at the port within the factory premises. The entire roof of the vehicle, including the driver's seat area, is flat, and all of the more than ten tires are capable of turning, allowing for lateral movement. Since the vehicle was custom-made by a special vehicle manufacturer, it is "one of a kind" in the world, and due to its shape constraints, major components such as the engine also have special shapes. As this vehicle aged, Company A requested the special vehicle manufacturer to overhaul key components like the engine; however, since the vehicle itself is a custom product, replacement parts for the overhaul must be newly manufactured. Therefore, the special vehicle manufacturer suggested to Company A to consider replacing it with a new vehicle. Company A, taking into account both cost and environmental aspects, expressed a desire to continue using the old vehicle and consulted with us.
