C15
Caterpillar

The remanufactured CAT C15 Long Block is not merely a used engine; it is a legacy of power reborn. This legendary 15.2L inline-six diesel engine is meticulously rebuilt to meet or exceed original OEM specifications, offering the renowned performance and durability of the C15 at a significant value. Ideal for fleet managers and owner-operators, it provides a reliable, cost-effective alternative to a new engine, backed by robust warranties for complete peace of mind.
Primary Equipment Applications
The C15 is a versatile and powerful platform designed for heavy-duty applications:
On-Highway Trucks: Extensively used in long-haul trucks, particularly models from Peterbilt and Kenworth.
Industrial & Marine Equipment: Also powers various industrial machinery and marine applications, with specific models built for these demanding environments.
The value of this product lies in its comprehensive and precise remanufacturing process, which ensures every unit performs like new.
State-of-the-Art Rebuilding: Every long block undergoes a complete teardown. Core components—including the engine block, cylinder head, crankshaft, camshaft, and connecting rods—are meticulously inspected using magnafluxing and pressure testing.
Precision Machining: All parts are machined to exact OEM specifications. The block is align-bored and honed, the cylinder head deck is resurfaced, and valve seats are machined and vacuum-tested.
Assembly with New Components: The engine is assembled with a complete set of new critical parts, including piston kits, rings, bearings, valves, guides, and gaskets. This process often incorporates superior aftermarket improvements, such as induction-hardened cylinder liners for reduced wear.
Stringent Quality Assurance: The entire process follows documented, high-quality manufacturing principles, ensuring consistency and reliability in every engine.
Below are the key specifications for the remanufactured CAT C15 long block.
