The Wacker Neuson Cylinder Head is a genuine OEM Cylinder Head designed for a wide range of Wacker Neuson equipment, including the RD12A-90 tandem rollers, BFS 2020AS saw, GS12Ai, and CRT36-26A and CRTv36-26A trowel series. Sourced directly from Wacker Neuson, this part carries the same specifications as the component installed at the factory, ensuring a correct, confident fit every time. It also covers multiple configuration variants across the CRT36-26A and CRTv36-26A lines, including standard, foldable ROPS, and wheel kit-equipped models. If you're restoring engine performance or completing a top-end rebuild, part number is the right choice for the job.
Key Features
- OEM-Spec Combustion Chamber Geometry — Manufactured to Wacker Neuson's original dimensions, preserving correct compression ratios and combustion efficiency across all covered engine applications.
- Direct Drop-In Replacement — Matches original port locations, bolt patterns, and mating surfaces so it seats correctly against the engine block and head gasket without rework.
- Broad Wacker Neuson Fitment — A single part number covers the RD12A-90 roller series, BFS 2020AS saw, GS12Ai, and the full CRT36-26A and CRTv36-26A trowel range, including foldable ROPS and wheel kit variants.
- Restored Engine Output — A properly sealed cylinder head maintains compression, which is critical to consistent power delivery in compaction and finishing equipment operating under sustained load.
- Genuine Wacker Neuson Part — Supplied as an authorized OEM component under part number 5000226409, giving you full confidence in material grade, machining tolerances, and long-term durability.
The cylinder head forms the top of the engine's combustion chamber, sealing it against the block and housing the valves that control the intake of air and fuel and the exhaust of combustion gases. It works together with the head gasket to maintain the compression pressure the engine needs to run efficiently — a warped, cracked, or worn cylinder head allows compression to escape, leading to hard starting, loss of power, overheating, or coolant and oil contamination. Replacing a failed cylinder head with a correctly spec'd OEM part restores proper engine function and prevents further damage to pistons, valves, and surrounding components.
