The Honda 12000-ZA0-702 Cylinder Assembly is a genuine OEM Cylinder Assembly designed for GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct Honda OEM replacement, this assembly is manufactured to the same specifications as the original, ensuring a proper fit without rework or modification. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes cylinder assemblies at serial breaks and the correct assembly must match your specific unit.
Key Features
- Genuine OEM Construction — manufactured by Honda to the same tolerances as the original cylinder, preserving bore geometry, port alignment, and deck surface integrity that aftermarket castings can struggle to replicate
- Direct-Replacement Fit — engineered to accept the original pistons, rings, valvetrain components, and gaskets without alteration, keeping the rebuild straightforward
- Broad OEM Fitment — covers GX360 horizontal shaft engines, EL5000, ES6500, and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors, including multiple serial ranges within those models
- Verify Your Serial Number — Honda issues revised cylinder assemblies mid-production; check your machine's serial number against the compatibility table to confirm this is the right assembly for your unit
- Restores Full Compression — a cylinder with worn bore walls or damaged deck surfaces causes compression loss, rough running, and oil consumption; replacing it with this assembly brings combustion back to spec
The cylinder assembly is the structural core of the engine — a precision-bored casting that houses the piston and rings, forms the combustion chamber alongside the cylinder head, and transfers combustion forces into crankshaft rotation. The bore surface must maintain a precise diameter and finish to allow the piston rings to seal correctly; when that surface wears or scores, combustion gases blow past the rings, compression drops, oil consumption climbs, and power falls away. Replacing a damaged or worn cylinder assembly with part number 12000-ZA0-702 restores the sealing surface the engine depends on and returns it to the output and efficiency it was built to deliver.
