3408C
Caterpillar
The CAT 3408C stands as a pinnacle of heavy-duty diesel engineering, a turbocharged V8 engine renowned for its unmatched combination of raw power, legendary durability, and exceptional reliability. Designed to conquer the most demanding applications, from large-scale earthmoving to continuous industrial power generation, the 3408C delivers robust performance where it matters most. Its proven mechanical design and robust construction ensure maximum uptime and a long service life, making it the trusted power source for critical operations worldwide.
The 3408C engine is the heart of some of the world's toughest machinery across multiple industries:
Heavy Earthmoving & Construction: Primarily powers large-track-type tractors (bulldozers), such as the Cat D9 series, where it provides the immense torque needed for pushing and excavation.
Mining & Quarrying: Found in large mining trucks, excavators, and other high-productivity equipment that operates in severe conditions.
Power Generation: Serves as a highly reliable prime mover for standby and continuous-operation generator sets.
Marine Applications: Used in workboats, tugs, and fishing vessels for both propulsion and auxiliary power due to its compact V8 footprint and high power output.
Specialized Heavy Trucks: Historically used in certain models of heavy-duty on-highway trucks from manufacturers like Kenworth and Peterbilt for severe-service hauling.
The legendary status of the 3408C is built upon several foundational engineering strengths:
Robust V8 Architecture & Construction: The engine features a high-strength cast-iron cylinder block with a 90-degree V8 configuration, offering an excellent balance of compact size and smooth operation. Critical components like the crankshaft undergo specialized nitriding treatments for extreme hardness and durability.
Proven PT Fuel System: A hallmark of its design is the reliable mechanical Pressure-Time (PT) fuel system. This system uses fuel pressure and a timed injection window to precisely meter fuel, offering rapid response and simplified high-pressure plumbing compared to other systems.
Efficient Turbocharging & Aftercooling: Equipped with a turbocharger and aftercooler (intercooler), the system significantly increases intake air density. This technology boosts power output and overall efficiency while managing thermal loads under continuous heavy operation.
Durability-Enhancing Design: Key features include centrifugally cast cylinder liners with honed surface patterns for optimal oil retention, a high-capacity gear-driven lubrication system, and a design focused on serviceability with components arranged for easier maintenance.
The table below summarizes the core specifications of the CAT 3408C industrial diesel engine.
