The Wacker Neuson Cylinder Head is a genuine OEM Cylinder Head designed for the RD12A-90 tandem roller series, BFS 2020AS saw, GS12Ai, and CRT36-26A and CRTv36-26A trowel series. Sourced directly from Wacker Neuson, this is the same part installed at the factory — no guesswork on fitment or compatibility. The covers an extended range of Wacker Neuson machines, making it a reliable choice whether you're servicing a roller, saw, or power trowel. Keep this part number on hand for planned maintenance or unscheduled repairs across your fleet.
Key Features
- Genuine OEM Combustion Integrity — Manufactured to Wacker Neuson's exact tolerances for combustion chamber geometry and sealing surface finish, ensuring correct compression and efficient fuel burn.
- Direct-Fit Replacement — Matches the original bolt pattern, port configuration, and gasket mating surfaces, so installation follows the standard service procedure without rework.
- Broad Wacker Neuson Fitment — Confirmed for RD12A-90 tandem rollers, BFS 2020AS saw, GS12Ai, CRT36-26A trowels, and CRTv36-26A trowels across multiple serial configurations.
- Sustained Engine Output — A correctly sealed cylinder head maintains proper compression, supporting full rated power and consistent performance under continuous jobsite loading.
- Safety-Critical Sealing — A compromised cylinder head can cause coolant or combustion gas leaks that elevate operating temperatures and create unsafe running conditions; an OEM replacement restores the designed safety margin.
The cylinder head forms the top of the engine's combustion chamber, sealing the cylinder bore and housing the intake and exhaust valves, as well as the spark plug or injector port depending on engine type. It works together with the head gasket to contain combustion pressure and direct the flow of intake charge and exhaust gases through the engine. When a cylinder head cracks, warps, or develops a compromised sealing surface, compression drops, coolant can enter the combustion chamber, and the engine will run rough, overheat, or fail to start — making timely replacement essential to keeping the machine operational.
