Model Number:
C18
This is a complete C18 diesel engine assembly for CAT equipment, built as a 6 cylinder in-line, 18.1 litre, turbocharged and aftercooled ACERT engine. The reference build is Engine Arrangement 359-1812, rated 630 hp at 2100 rpm — the same output quoted as 470 kW for the E390D. Because the C18 name covers mobile, generator and industrial ratings, the arrangement number and the rating are what identify the correct engine.

The same C18 name covers a 630 hp at 2100 rpm mobile arrangement, a 600 ekW at 1800 rpm generator drive and an 800 hp industrial build. Turbocharger, governor, flywheel housing and rating differ between them, so the arrangement number and the rating are what must match.
Several sellers list 319-6715; 3196715 as a hydraulic diesel piston body assembly for C18, C27 and C32 at a few tens of dollars per set. It sits inside engine assembly searches and is a component of the engine rather than an engine.
Titles bundle 3306, 3406, 3408, C11, C13, C15, C18, C27 and C32 in one line, and several quote a single set price across all of them. These are engines of different displacement and mounting, and a C15 does not replace a C18.
The same search returns a few hundred dollars per piece, tens of thousands per piece, tens of thousands per dozen, and one listing spanning a sixfold range inside a single number. Compare per single engine and confirm the condition tier in writing.
