The Wacker Neuson is a genuine OEM Complete Cylinder Head Left designed for the RD11AEC and RD11A hydrostatic double drum vibratory tandem rollers. As a factory-sourced component, it is manufactured to the exact tolerances and material specifications required by the original engine configuration on these machines. This part is the correct left-side cylinder head assembly for RD11 series tandem rollers and installs as a direct replacement with no adaptation needed. If your RD11AEC or RD11A is showing signs of head failure — overheating, loss of compression, coolant loss, or visible cracking — part number is the factory-correct solution.
Key Features
- OEM Combustion Integrity — Cast and machined to factory combustion chamber geometry, ensuring correct compression ratios and sealing surface flatness for the RD11 engine.
- Left-Side Specific Assembly — Designed exclusively for the left cylinder bank; port orientation, mounting bolt pattern, and gasket surface match the original left-hand position exactly.
- RD11AEC and RD11A Compatibility — Confirmed fitment for both the RD11AEC and RD11A hydrostatic double drum vibratory tandem rollers in the RD11 series.
- Compression and Cooling Restored — A failed or cracked cylinder head causes coolant intrusion, power loss, and overheating; replacing with 5000151865 restores proper compression and thermal management.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number and build standard as the original component installed at the factory.
The cylinder head seals the top of the engine's combustion chamber, containing the high pressures generated during the power stroke while also forming part of the cooling jacket that manages engine temperature. On a tandem roller like the RD11AEC and RD11A, where the engine is under sustained load during compaction passes, a compromised cylinder head can lead to coolant mixing with oil, loss of compression, and eventual engine damage. Replacing a worn or cracked head with a correctly specified unit like the 5000151865 is essential to keeping the engine running at full power and within safe operating temperatures.
