The Honda 12000-Z1E-405 Cylinder Assembly is a genuine OEM Cylinder Assembly designed for GXV390 vertical shaft engines, including H2013 and H2113 lawn tractors, H3011 and H3013 riding mowers, and HRC7013 and HRC7113 commercial mowers. As a factory-original component, this assembly is manufactured to Honda's exact tolerances, ensuring a correct fit for the applications it covers. Verify your machine's serial number against the fitment table to confirm this is the right assembly for your specific unit before ordering.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this Cylinder Assembly meets the exact dimensional and material specifications Honda set for the GXV390 engine platform — no guesswork on bore sizing or port geometry.
- Broad Fitment Coverage — fits GXV390 vertical shaft engines as used in H2013 and H2113 lawn tractors, H3011 and H3013 riding mowers, and HRC7013 and HRC7113 commercial mowers, including models covered by part number 12000-Z1E-405.
- Serial Number Verification Recommended — Honda supersedes cylinder components at production breaks; always confirm your machine's serial number against the fitment table to ensure this is the correct assembly for your unit.
- Core Engine Integrity — a sound cylinder is what allows the engine to build and hold compression; a cracked, worn, or damaged bore leads to loss of power, excessive oil consumption, and eventual engine failure.
The cylinder assembly is the central structural and functional core of the engine. It forms the bore in which the piston travels, houses the combustion chamber, and provides the mounting points for the cylinder head, crankcase, and ancillary components. Combustion pressure acts directly against the cylinder walls, so dimensional accuracy of the bore is critical to compression, power output, and oil control. When a cylinder is worn beyond its service limit — or damaged by overheating, lack of lubrication, or a mechanical failure — compression drops, oil consumption rises, and the engine loses the ability to perform reliably. Replacing a damaged or out-of-tolerance cylinder assembly with a genuine Honda unit restores the foundation the rest of the engine depends on.
