This CAT C18 Marine Engine Assembly (part number 366-5513) is a complete, ready-to-fit diesel power unit. As a full Engine assembly, it arrives as one integrated package — cylinder block, cylinder head, crankshaft, pistons, liners, connecting rods, bearings, turbocharger, fuel system and cooling circuit — so a single order replaces dozens of individual lines and puts your Marine Engine back to work with minimal downtime.
Every CAT Marine Engine in this build is cleaned, inspected and re-machined to CAT reference tolerances: cylinder bores are honed, crankshaft journals reground and bearing clearances matched for stable oil pressure and smooth running. The result performs like the original power pack while fitting the same mounts, manifolds and control interfaces — a practical, cost-effective alternative to a brand-new engine for shipyards, fleet operators and workshops that regularly source Excavator Engine Parts and marine power solutions.
With an 18.1-litre displacement and ratings up to 597 kW (800 bhp), the C18 is trusted for continuous heavy-duty duty cycles. Whether you are repowering a tug, refitting a workboat or rebuilding an excavator, this Marine Engine assembly delivers dependable torque and long service life in some of the world's toughest operating environments.
