The Honda 12251-ZG6-003 Cylinder Head Gasket (1.25) is a genuine OEM replacement designed for the H6522 compact tractor. As a direct Honda OEM part, it is manufactured to the exact tolerances required for proper combustion sealing on this machine. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes gasket part numbers at production breaks and the correct grade must match your engine's specification.
Key Features
- OEM Combustion Sealing — engineered to Honda's exact clamping and compression specifications for the H6522, ensuring the cylinder head seats correctly and combustion pressure is fully contained
- Variant-Specific Grade — the (1.25) designation identifies the thickness grade of this gasket; matching this specification to your engine's head and deck surfaces is essential for correct compression
- Direct OEM Replacement — genuine Honda part number 12251-ZG6-003 replaces the original gasket on the H6522 compact tractor with no adaptation required
- Serial Number Verification Recommended — Honda updates cylinder head gasket part numbers at serial breaks; check your machine's serial number against the fitment table to confirm this is the correct grade for your unit
A cylinder head gasket forms the critical seal between the cylinder head and the engine block, preventing combustion gases from escaping while also keeping coolant and oil passages separated. When this gasket fails or deteriorates, the engine may lose compression, overheat, or show signs of oil or coolant contamination — any of which will cause serious performance loss or engine damage. Installing the correct OEM-grade gasket with the right thickness specification restores the sealing integrity the engine depends on for consistent, full-power operation.
