Description
Power your toughest machinery with a high-quality Caterpillar 3408 or 3408 HEUI Diesel Engine Basic Long Block. These V8 diesel engines are legendary for their raw power, durability, and reliability in demanding applications. The final price depends on your specific setup and any required configurations.
The Caterpillar 3408 is a formidable 18.0-liter (1,099 cubic inch) V8 diesel engine, purpose-built for extreme duty. Its reputation comes from its immense power output and long service life. We specialize in configuring the Caterpillar 3408 engine with the advanced HEUI (Hydraulically Actuated Electronic Unit Injection) fuel system. This innovative system uses engine oil pressure to create very high fuel injection pressure. This results in precise fuel delivery, better fuel efficiency, and reduced emissions compared to older mechanical systems.
Key Features and Performance:
- Engine Configuration: These are V8, 4-stroke cycle diesel engines. They feature a rugged cast-iron block and cylinder heads, built for maximum endurance.
- Massive Displacement: At 18.0 Liters, these engines deliver exceptional power and torque. This makes them ideal for the biggest jobs in the harshest environments.
- HEUI System (for applicable models): The HEUI fuel system provides electronically controlled, high-pressure fuel injection. This translates to improved fuel economy, lower emissions, and highly responsive power delivery.
- High Horsepower & Torque: The 3408 series typically offers substantial horsepower ratings, often ranging from 400 HP up to over 800 HP. They provide immense torque, essential for heavy hauling, crushing, drilling, and driving large industrial equipment.
- Unmatched Durability: Caterpillar designed these engines for severe-duty cycles. They boast a rugged construction with heavy-duty internal components, ensuring maximum uptime and a very long service life.
Common Applications:
The sheer power and reliability of the Caterpillar 3408 and 3408 HEUI engines make them ideal for the most demanding environments, including:
- Large Mining Trucks and Equipment: Haul trucks, excavators, and draglines.
- Oil and Gas Industry: Drilling rigs, well service pumps, and power generation.
- Marine Propulsion: Powering large vessels and tugboats.
- Power Generation: Providing primary power for large generator sets in industrial and standby applications.
- Heavy Construction: Large loaders, dozers, and scrapers.
- Industrial Power Units: Delivering consistent power for various heavy industrial operations.
Our Caterpillar 3408 and 3408 HEUI Basic Long Blocks are meticulously prepared. This ensures a reliable and powerful engine solution for your critical applications.

ENGINE TESTING
Every engine is machined using state-of-the-art equipment and assembled using precise and repeatable methods. All engine production follows documented lean manufacturing processes and principles to create consistent quality and dependable outcomes.
All Short Block, Long Block, and Long Block Premium are 100% Sim tested before shipment.
Complete Drop-In engines are 100% dyno tested before shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm-up cycle; three separate cruise segments simulating light, medium, and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a black light leak detection test with dyed oil, coolant, and fuel.
we’ve been delivering remanufactured engines for skid steer loaders for over 30 years—longer than any competitor in the industry. Our veteran machinists, many with decades of experience, follow engine-specific rebuild procedures to ensure consistent quality with every unit.
Each engine is carefully rebuilt to meet or exceed OEM specifications, using top-tier components and proven techniques. This is more than just a repair—it’s a full remanufacturing process designed to restore the engine to like-new condition.
Before shipping, every complete skid steer engine is dyno-tested for performance and reliability, so you can install with confidence.
