Description
Power your most demanding heavy-duty applications with a high-quality Caterpillar C-15 Diesel Engine Long Block. These iconic 15.2L (927.6 in³) inline-6 diesel engines are renowned for their robust design and exceptional performance. The final price will depend on your specific configuration and any additional requirements.
The Caterpillar C-15 engine, including its later ACERT (Advanced Combustion Emissions Reduction Technology) variants, is a workhorse in the heavy-duty industry. Developed as an evolution of the reliable 3406E, the C-15 aims to provide improved reliability and meet stricter emissions standards.
Key Features and Performance:
- Engine Configuration: Inline-6, 4-stroke cycle diesel with a cast-iron block and head.
- Displacement: 15.2 Liters (927.6 cubic inches).
- Horsepower & Torque: The C-15 and C-15 ACERT engines typically range from 435 to 600+ Horsepower, with peak torque figures often exceeding 1,550 lb-ft to over 2,000 lb-ft depending on the specific rating and application.
- Fuel System: Utilizes advanced electronic fuel injection, including Mechanical Electronic Unit Injectors (MEUI) and ACERT Technology for precise fuel delivery, optimizing fuel efficiency and reducing emissions.
- Durability: Built with a rock-solid design for durability, featuring robust internal components and improvements over previous models, such as better gaskets and seals to mitigate common leak issues.
- Advanced Control System: Electronic governing, programmable ratings, automatic altitude compensation, power compensation for fuel temperature, and comprehensive electronic diagnostics with fault logging.
Common Applications:
The C-15 engine’s versatility and raw power make it a top choice across numerous heavy-duty sectors:
- Heavy-duty Highway Trucks: A very popular choice for owner-operators and fleets, particularly in Peterbilt and Freightliner vehicles, for long-haul freight and regional haul applications.
- Construction Equipment: Including excavators, wheel loaders, dozers, compactors, cranes, crushers, and paving equipment.
- Mining Operations: Powering a variety of large-scale mining machinery.
- Agricultural Equipment: Such as combines, harvesters, and large agricultural tractors.
- Industrial Applications: Generators, power units, hydraulic power units, and other specialized heavy industrial equipment.
- Specialized Vehicles: Fire/emergency vehicles, tanker and bulk carriers, logging and forestry trucks, and oil field service vehicles.

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.
