What does it take to rebuild the world’s biggest truck engines? We visited Finning Cat in Antofagasta, Chile, to find out.

Caterpillar has been a world leader in rebuilding engines and entire machines for decades. Instead of sending million-dollar power plants to the scrapyard after a single useful life, they rebuild them to original specification using brilliant re-manufacturing techniques.

On the mine sites, technicians are swapping old engines for new ones regularly. After transport, they arrive at Finning’s CRC, where disassembly and cleaning commence.

Once they’ve identified how each engine or component is worn, they get to work rebuilding it. They add metal (by spraying it) and machine the block, replace all hoses, filters, and harnesses, and swap any damaged components.

Upon completion, they test every engine under full loading, paint them, and ship them back to the mines.
