The Remanufacturing Process of Cylinder Heads

A remanufactured cylinder head is a cylinder head that has been restored by a specialist to meet the original manufacturer's specifications. As with any reconditioned part or diesel engine, the intention of this process is to produce cost-efficient, environmentally friendly alternatives to purchasing new components.

Here, we will outline our step-by-step process for remanufacturing cylinder heads, ensuring
you can ask all the right questions when contacting us.

Step One: Inspection and Disassembly
Our experts begin the cylinder head remanufacturing process with a comprehensive inspection. We disassemble the cylinder head and examine each component for wear, cracks, and other defects. This rigorous assessment determines the feasibility of remanufacturing and identifies which components must be replaced.

Step Two: Pressure Testing
We conduct a pressure test to verify the integrity of the cylinder head. This is essential to ensure that no cracks or leaks could affect engine performance. After all, any defects discovered during this step prompt corrective actions to boost longevity and performance in the long run.

Step Three: Cleaning and Degreasing
The next step involves thorough cleaning and degreasing. The cylinder head is immersed in specialised solutions and subjected to high-pressure cleaning to remove contaminants, carbon deposits, and old gasket material. This step allows the cylinder head to function efficiently, resulting in better engine performance and a longer lifespan.

Step Four: Resurfacing
Cylinder head resurfacing is crucial to ensure a perfectly flat and smooth sealing surface. We carry out milling or grinding processes to achieve the required surface finish, which is vital for preventing leaks and ensuring optimal compression.

Step Five: Valve and Seat Refurbishment
Valves and valve seats are crucial in the cylinder head's performance. During remanufacturing, worn or damaged valves are replaced, and the valve seats are machined to ensure a perfect seal. This step enhances engine efficiency and reduces emissions.

Step Six: Assembly and Component Replacement
In this phase, our team installs new valve guides, stem seals, springs, and other necessary components. The cylinder head is reassembled, ensuring precision in valve settings and tolerances.

Step Seven: Final Washing
Next, we wash the cylinder head to eliminate excess components like solvents and grime to optimise the performance.

Step Eight: Final Inspection and Packaging
The remanufactured cylinder head undergoes a final inspection to ensure it is free of defects and meets quality standards. Finally, it is packaged and prepared for shipping so customers can start to enjoy the benefits of what remanufactured cylinder heads have to offer.

At Foxwood Diesel, we strongly believe that quality control is a continuous process throughout remanufacturing. The cylinder head undergoes rigorous inspections at multiple stages to ensure it meets or exceeds OEM specifications.

Now that you know the process of remanufacturing cylinder heads, it might be worth learning why you should go through this process in the first place. Check out the main benefits below.

● Cost-Effective
Remanufactured cylinder heads are more affordable than new components, which can be handy for businesses with lower budgets.

● Sustainable
As previously mentioned, remanufacturing can offer a sustainable outcome by extending the lifespan of existing components. This helps to reduce waste and conserve resources in the long run.

● Quality Assurance
Our team thoroughly inspects and tests remanufactured cylinder heads, ensuring they meet or exceed OEM specifications. This reduces the chance of acquiring issues. However, you should still look out for the main symptoms of cylinder head problems and address these immediately if they crop up.

● Performance Enhancement
Remanufactured cylinder heads can enhance engine performance through resurfacing, valve work, and other improvements, helping keep your diesel engine in good condition.

Hopefully, you now know a little more about the process of remanufacturing cylinder heads and how crucial it is for keeping your favourite vehicle running. 
Remanufactured parts are ideal for business owners, bus fleet managers, and individuals wanting to save extra money and help out the environment at the same time, all whilst enjoying the enhanced reliability and performance of these reconditioned components.
