The Wacker Neuson Cylinder Head Assembly is a genuine OEM component designed for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers. As a factory-sourced assembly, this part is manufactured to the exact tolerances and specifications required for the engine configuration found in these RD27 series machines. Correct cylinder head sealing is critical to maintaining compression, combustion efficiency, and engine longevity — making it essential to use the right assembly for your specific roller model. Confirm your machine's model and serial number against before ordering to ensure a direct match.
Key Features
- OEM Combustion Integrity — Manufactured to the exact compression and sealing specifications required by the RD27 series engine, ensuring consistent combustion performance across the assembly.
- Complete Head Assembly — Supplied as a full assembly, reducing installation complexity and ensuring all mating components are dimensionally matched from the factory.
- Direct Fitment for RD27 Tandem Rollers — Engineered specifically for the RD27-100 and RD27-120 hydrostatic vibratory tandem rollers used in asphalt and soil compaction applications.
- Engine Protection — A correctly seated cylinder head maintains proper compression ratios and prevents coolant or combustion gas leaks that can lead to rapid engine damage if left unaddressed.
- Critical Fuel System Boundary — The cylinder head forms part of the combustion chamber boundary; a failed or warped head directly compromises fuel burn efficiency and can result in loss of machine power or unplanned downtime on compaction projects.
The cylinder head assembly forms the upper seal of the engine's combustion chamber, housing the valves, valve seats, and ports that manage the intake of air-fuel mixture and the exhaust of combustion gases. It works in conjunction with the head gasket and engine block to maintain the pressure needed for efficient power generation. When a cylinder head warps, cracks, or develops a leak, compression drops, the engine loses power, and coolant or oil contamination of the combustion chamber can cause rapid internal damage — making timely replacement with the correct OEM assembly essential for keeping the RD27 roller operational.
