The Honda 12000-Z5T-418 Cylinder Assembly (Fujikoshi) is a genuine OEM replacement built for GX390 horizontal shaft engines, HS928 and HS1332 two-stage snow blowers, and HSS928 and HSS1332 two-stage snow blowers. This cylinder assembly is manufactured by Fujikoshi to Honda's exact specifications, ensuring dimensional accuracy across bore diameter, porting, and cooling fin geometry. As a direct OEM replacement, this part restores the structural core of the engine to original condition — a critical factor when rebuilding a powerplant that sees the sustained, heavy-load demands of commercial-grade snow removal equipment and the wide range of applications the GX390 engine powers.
Key Features
- Fujikoshi OEM Manufacture — cast and machined by Fujikoshi under Honda's original tooling specifications, delivering the bore geometry and cooling-fin profile the GX390 engine family requires
- Correct Bore Dimensions — an accurately bored cylinder maintains proper ring-to-wall sealing and piston clearance, directly affecting compression, oil consumption, and long-term engine health
- Broad Fitment Across Honda Equipment — designed for GX390 horizontal shaft engines, HS928 and HS1332 two-stage snow blowers, and HSS928 and HSS1332 two-stage snow blowers; verify your serial number against the fitment table before ordering, as Honda supersedes cylinder assemblies at production breaks
- Foundation of Engine Rebuild — a worn, cracked, or scored cylinder causes compression loss, excessive oil use, and accelerated wear on pistons, rings, and bearings; replacing this assembly restores the engine's ability to develop full power output
The cylinder assembly is the central structural casting of a four-stroke engine. It houses the piston and piston rings within a precision-bored sleeve, forms the combustion chamber walls, and provides the mounting foundation for the cylinder head above and the crankcase below. Cooling fins cast into the exterior dissipate heat generated during combustion, keeping operating temperatures within safe limits. When the bore becomes worn, scored, or out-of-round — whether from hours of hard use, a lubrication failure, or ingested debris — compression drops, oil consumption rises, and the engine loses the power needed to drive the equipment it serves.
