The Honda 12000-Z1F-405 Cylinder Assembly is a genuine OEM Cylinder Assembly designed for GXV340 vertical shaft engines. As a direct Honda OEM component, this assembly is manufactured to the exact specifications of the original part it replaces, ensuring proper fitment without adaptation. Honda supersedes parts at serial number breaks, so buyers should verify their engine serial number against the fitment table before ordering to confirm this is the correct assembly for their unit.
Key Features
- Genuine Honda OEM Construction — machined and finished to the same tolerances as the original, so bore dimensions, port geometry, and deck surface align precisely with GXV340 specifications.
- Core Engine Structure — this assembly forms the foundation that houses the piston, rings, and associated components; a cracked, worn, or damaged cylinder directly affects compression, oil control, and overall engine output.
- Fits GXV340 Vertical Shaft Engines — sourced specifically for the GXV340 platform; confirm compatibility using your engine serial number and the fitment table before purchasing.
- Serial Number Matters — Honda releases updated cylinder assemblies at defined production breaks; checking your serial number ensures you receive the assembly that matches your engine's build.
The cylinder assembly is the structural core of the engine. It provides the bore in which the piston travels, contains the combustion chamber, and channels coolant and oil to keep the engine running within safe operating temperatures. When a cylinder is cracked, scored, or worn beyond service limits, the engine loses compression, burns oil, and cannot develop full power — making a proper cylinder assembly essential to restoring the engine to its original operating condition.
