The Incredible Process of Rebuilding the Biggest Truck Engines in the World

TLDRFollow the step-by-step process of rebuilding massive truck engines in Chile, from disassembling and cleaning the components to reassembling and testing the engines. This in-depth video gives a behind-the-scenes look at the precision and skill involved in refurbishing these powerful engines.

Key insights

🔧The engine rebuilding process starts with disassembling and cleaning the components, including giant washing machines for thorough cleaning.

💡Special non-destructive testing techniques are used to detect any cracks or defects in the engine components.

🌐The reconditioning of the engines requires precise calibration of the tools used in the process.

🔬Robotic metal spraying is employed to add additional metal to damaged parts, which is then machined to perfection.

🚚The refurbished engines are tested in dynos and then carefully packaged for shipment back to the mines.

Q&A
