The Honda 12000-ZE2-408 Cylinder Assembly (Balancer+Alert) is a genuine OEM component designed for GX240 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original unit, ensuring dimensional accuracy and proper integration with all mating engine components. This assembly is specifically the Balancer+Alert variant — confirm that this variant matches your original unit before ordering, as Honda offers this cylinder in more than one configuration. Verify your engine's serial number against the fitment table to confirm this is the correct part for your GX240.
Key Features
- Genuine Honda OEM Assembly — sourced directly from Honda, this cylinder assembly meets the original design specification for the GX240, covering bore geometry, porting, and integration with the balancer and oil alert systems included in this variant.
- Balancer+Alert Variant — this specific configuration incorporates the balance shaft provisions and oil alert system passages; match this variant designation to your existing assembly before ordering.
- GX240 Horizontal Shaft Engine Fitment — built exclusively for the GX240 engine; check your engine serial number against the fitment table to confirm applicability to your production range.
- Structural Core of the Engine — a correctly dimensioned cylinder assembly maintains bore integrity for piston sealing and supports the crankshaft, camshaft, and balancer shaft in proper alignment; a cracked, worn, or out-of-specification cylinder causes compression loss, oil consumption, and accelerated wear across the entire engine.
The cylinder assembly is the primary structural casting of the engine. It houses the piston and bore, provides mounting points for the cylinder head above and the crankcase below, and — in this Balancer+Alert variant — incorporates the passages and provisions for both the balance shaft assembly and the oil alert system. The balance shaft reduces the vibration inherent in a single-cylinder engine, extending the working life of the equipment it powers and improving operator comfort. The oil alert provisions allow the low-oil protection system to function correctly, shutting the engine down before oil starvation causes catastrophic internal damage. When a cylinder assembly is cracked, excessively worn, or damaged, no amount of piston or ring replacement will restore compression or oil control — replacing the assembly is the correct course of action.
