One New Aftermarket Replacement Piston Crown (Crown As-Piston) for Caterpillar (Cat) 3406E and C15 Diesel Engines
This aftermarket replacement piston crown fits Caterpillar (Cat) 3406E and C-15 heavy-duty diesel engines. The piston crown is the upper section of a two-piece articulated piston assembly, subject to extreme combustion heat and pressure during engine operation. Worn or damaged piston crowns can cause engine knock, excessive oil consumption, and loss of compression -- replacement is a standard step in engine overhaul and rebuild work. Compatible with C15 serial number prefixes 6NZ, 9NZ, and MBN; verify your engine serial number prefix before ordering, as piston specifications can vary by serial number range.
