Cat C7 Remanufactured Engine: Legendary Power, Reborn with Guaranteed Performance

The Cat C7 Remanufactured Engine represents the perfect fusion of a proven industrial power legend and state-of-the-art renewal technology. We take the core of the renowned C7—an engine celebrated for its durability and versatility—and restore it to meet or exceed original OEM specifications through our proprietary Cat Reman process. The result is an engine that delivers the same reliable performance, power, and warranty as a new Cat C7, but at a significantly reduced cost and environmental footprint. It's the smart, sustainable choice for reviving your equipment with confidence.

Target Equipment & Applications

The C7 engine is designed for versatility, making the remanufactured version a cost-effective power solution for a vast range of medium-duty machinery across multiple industries. Primary applications include:

  • Construction & Earthmoving Equipment: Skid-steer loaders, excavators, wheel loaders, and compactors.

  • Material Handling & Industrial Machinery: Forklifts, agricultural tractors, harvesters, irrigation pumps, and mobile hydraulic power units.

  • Specialized Vehicles: Frequently found in dump trucks, refuse vehicles, and other vocational trucks requiring reliable torque.

  • Power Generation: Serves as a dependable prime mover for generator sets.

Core Technologies & Remanufacturing Advantages

  1. The Cat Reman Guarantee: Unlike simple repair or rebuilding, every Cat Reman C7 engine undergoes a complete teardown to its smallest parts. Each component is meticulously cleaned, inspected, and restored using advanced repair techniques like laser cladding and machining to precise factory tolerances. The engine is then reassembled with a mix of reused-core, reconditioned, and brand-new critical parts, integrating the latest engineering updates to ensure optimal performance. Each unit is rigorously tested to meet new engine standards.

  2. Proven C7 Engine Platform: The C7 is a 7.2-liter, turbocharged-aftercooled inline 6-cylinder diesel engine. Its robust design features a strong cylinder block and a gear-driven front end for durability.

  3. Advanced Fuel & Combustion System: The C7 utilizes the advanced HEUI (Hydraulic Electronic Unit Injection) fuel system, which provides precise fuel delivery for excellent throttle response, improved cold starts, and lower emissions. This system is a key component of Cat's ACERT® Technology, designed to meet stringent emission standards efficiently.
