Cummins 6BTA5.9 Diesel Engine — with OEM Water Pump
This is a complete Cummins 6BTA5.9 engine assembly — the turbocharged and aftercooled version of Cummins’ legendary B-Series inline-six. Built for heavy-duty industrial and construction use, the 6BTA has powered excavators, loaders, dozers, and generator sets for decades thanks to its proven durability and straightforward mechanical design. Includes a fresh OEM-spec water pump, so it’s ready to bolt in and go to work.
The 6BTA5.9 is one of the most trusted mid-range diesel powerplants in the industry — known for strong low-RPM torque, simple mechanical fuel systems that are easy to service in the field, and a reputation for running hundreds of thousands of hours with proper maintenance. It’s a direct fit or repower solution for excavators, wheel loaders, skid steers, industrial generators, and other heavy equipment applications that demand reliable, no-nonsense power. Its mechanical (non-electronic) design means fewer sensors and modules to fail, making it a favorite for owners who value simplicity and long-term serviceability over complexity.
