3408
Caterpillar

The Caterpillar 3408 is a legendary heavy-duty V8 diesel engine celebrated for its exceptional durability, robust power, and remarkable versatility. Introduced in the 1970s and produced for decades, it has established an enduring legacy as a cornerstone in demanding industrial, marine, and construction applications. Renowned for its mechanical simplicity and long service life, the 3408 engine is engineered to provide reliable, high-performance power where it matters most.
The Cat 3408 is a true multi-industry workhorse, chosen for its ability to deliver consistent power under extreme conditions.
Marine Vessels: A dominant force for propulsion and auxiliary power in medium-sized vessels such as shrimp boats, tugboats, and ferries, thanks to its compact V8 design that fits well in engine rooms.
Power Generation: Widely used as a prime mover in diesel generator sets for prime, continuous, or standby power across industries like oil & gas, data centers, and large facilities.
Heavy Construction & Mining: Powers critical machinery including large excavators (e.g., Cat 245), off-highway trucks (e.g., Cat 777, 992C), bulldozers, and wheel loaders.
Industrial & Oilfield: Provides reliable power for pumps, compressors, and drilling rigs in the most challenging environments.
Robust V8 Architecture: As the V8 counterpart to the famous 3406 inline-six, this engine delivers a superior power-to-size ratio, offering high horsepower and exceptional torque—reportedly around 2,000 lb-ft or more in industrial configurations—ideal for heavy loads.
Legendary Durability & Longevity: The 3408 is engineered for a long operational life, with a design life expectancy of approximately 16,000 hours of operation. Its durable cast-iron construction ensures reliability in continuous, heavy-duty cycles.
Proven Performance Design: The engine evolved from a purely mechanical fuel injection system to advanced electronic fuel injection models in the 1990s, balancing modern control with mechanical reliability. This evolution ensured optimized fuel economy alongside high power output.
Continued Market Support: Although production ceased, the 3408 remains in high demand. A strong aftermarket ensures the ongoing availability of OEM and remanufactured parts, overhaul kits, and complete rebuilt engines, supported by a global network of diesel specialists.
