Durable Power for Heavy-Duty Work

The CAT 3408 HEUI is a remanufactured 18-liter diesel engine built for heavy-duty industrial and off-highway use. With advanced Hydraulic Electronic Unit Injection (HEUI) technology, it offers precise fuel delivery, reduced injector wear, and dependable combustion across long operating hours. This rebuilt 3408 is ideal for marine engines, power generators, and construction equipment needing reliable performance under pressure. Each engine is restored to OEM specifications, providing a trusted solution for operations requiring consistent torque and durability. The CAT C3408 HEUI stands out as a proven, rugged engine ready for demanding jobs.

The remanufacturing process for the Caterpillar 3408 engine begins with a complete teardown of the core. Every component is removed, cleaned, and carefully inspected for damage or wear. Vital parts like the crankshaft, camshaft, and cylinder heads are machined or replaced to meet original OEM specifications. Special attention is given to the Hydraulic Electronic Unit Injection (HEUI) system—each injector is bench-tested to ensure proper fuel delivery and consistent combustion performance.

After reassembly, the remanufactured engine is dyno-tested under load to confirm it meets CAT 3408 torque specs and delivers the power output expected from an 18L diesel engine. This process ensures the unit is ready for harsh field conditions, whether powering marine vessels, generators, or construction machinery. Known for its durability and reliability, the Caterpillar 3408 is a top choice among heavy-duty diesel engines. Many customers also compare it with options like our Cummins 6.7L reman engine for similar performance needs.
