The Honda 12000-ZE3-417 Cylinder Assembly (Self Starter+Alert) is a genuine OEM component built for a broad range of Honda generators, engines, tractors, and welder generators. This assembly is engineered to Honda's exact specifications and is the direct replacement for equipment running this cylinder configuration — the Self Starter+Alert variant is a critical detail to match against your own unit before ordering. As a genuine Honda part, it carries the same design and dimensional standards as the original, ensuring proper integration with the engine's bore, cooling passages, and mounting architecture.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this cylinder assembly matches the original bore geometry, cooling fin layout, and mounting interface required by the engine design
- Self Starter+Alert Variant — this specific configuration includes provisions for the electric self-starter and alert system; confirm your unit carries this same configuration before ordering
- Wide Fitment Coverage — designed for GX340 horizontal shaft engines, EB5000, EG5000, EM3800, EM4000, EM5000, EM6500, EX4500 generators, the EXW171 welder generator, and H5013 and RT5000 multi-purpose tractors
- Verify Your Serial Number — Honda supersedes cylinder assemblies at production breaks; check the serial number on your machine against the fitment table to confirm this is the correct part for your unit
- Restores Core Engine Integrity — a damaged or worn cylinder is the source of compression loss, excessive oil consumption, and overheating; replacing it with this genuine assembly brings the engine back to its original operating condition
The cylinder assembly is the structural and functional core of a four-stroke engine. It houses the piston and forms the combustion chamber where the air-fuel mixture is compressed and ignited, and its walls, cooling fins, and integrated passages manage the heat generated in that process. When a cylinder is cracked, scored, or worn beyond serviceable limits, the engine loses compression, burns oil, runs rough, and eventually fails to develop usable power — replacement is the only lasting remedy. This Self Starter+Alert version is specifically machined and cast to accommodate both the electric starter interface and the alert system found on select Honda generators, tractors, and the GX340 engine, making variant matching essential before this part is installed.
