The Wacker Neuson Cylinder Head is a genuine OEM component designed for the RD12A-90 Tandem Roller series and the BFS 2020AS Saw. As a direct manufacturer part, it meets the exact dimensional and material specifications required for a correct, lasting installation. This Cylinder Head is confirmed to fit multiple RD12A-90 configurations, including the standard, Foldable ROPS, and double drum variants, as well as the BFS 2020AS. Sourcing part number directly ensures you're getting the component built to the same standard as the original.
Key Features
- OEM Combustion Integrity — Manufactured to Wacker Neuson's exact bore geometry and sealing surface tolerances, so compression and combustion efficiency are maintained from the first start.
- Direct-Mount Replacement — Matches the original bolt pattern, port locations, and gasket surface of the factory head for a straightforward swap with no rework needed.
- Broad RD12A-90 Coverage — Fits the standard RD12A-90 Tandem Roller, the Foldable ROPS variant, and the double drum configuration, plus the BFS 2020AS Saw.
- Sustained Engine Output — A correctly seated cylinder head maintains proper compression ratios, keeping the engine producing full power under load. A warped or cracked head causes compression loss, hard starting, and overheating.
- Combustion Safety Compliance — A compromised cylinder head can allow exhaust gases or fuel vapor to escape into the engine bay; using a genuine OEM replacement preserves the designed containment and sealing of the combustion system.
The cylinder head forms the top of the engine's combustion chamber, sealing the bore and housing the intake and exhaust ports, valves, and in many designs the injector or spark plug. It works together with the head gasket and engine block to contain the high pressures generated during combustion and direct exhaust gases out of the engine. When a cylinder head cracks, warps, or develops a compromised sealing surface, compression drops, coolant or oil can enter the combustion chamber, and the engine will overheat or fail to run reliably — making prompt replacement with the correct part critical to getting the machine back to full working condition.
