Komatsu SAA6D107E (6.7L)

The Comprehensive Guide to the Industry's Hardest Working Engine

Komatsu SAA6D107E Long Block Engine

Built on a Legend: The Cummins 6.7L DNA

The Komatsu SAA6D107E is a 6.69L, six-cylinder diesel power plant co-developed through the Komatsu-Cummins joint venture. While it shares its core architecture with the Cummins QSB6.7, it is custom-tuned for the unique load-sensing hydraulics and high-torque demands of Komatsu heavy equipment. At Choate Engineering Performance, we remanufacture these engines to solve factory oiling and thermal flaws, ensuring your machine stays in the dirt and out of the shop.
