The Wacker Neuson Cylinder Head is a genuine OEM component designed for RD7 series tandem rollers and DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H diesel reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this cylinder head is manufactured to the exact specifications of the original part and integrates with the engine assembly as a direct replacement. It is compatible across a broad range of RD7H and RD7He roller variants as well as the full DPU H-series plate lineup, making it a widely applicable engine component for Wacker Neuson equipment fleets. Confirming your machine model number before ordering ensures a correct fit.
Key Features
- Genuine OEM Construction: — Cast and machined to Wacker Neuson's original dimensional and material specifications, ensuring proper combustion chamber geometry and sealing surface integrity for this engine application.
- Direct Engine Drop-In: — Matches the original bolt pattern, port layout, and valve seat configuration, allowing installation without machining or modification to the engine block.
- Broad RD7 and DPU Series Coverage: — Fits RD7H, RD7He, RD7Heh, RD7Hf, and related tandem roller variants, plus DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H reversible vibratory plates across multiple machine generations.
- Restores Full Engine Compression: — A cracked, warped, or leaking cylinder head causes loss of compression, overheating, and hard starting. Replacing it with this OEM unit restores proper power output and engine efficiency.
- Critical Fuel and Combustion Safety: — A correctly sealed cylinder head prevents exhaust gas leakage and fuel vapor ingress into the engine oil, both of which present operational and safety risks on diesel-powered compaction equipment.
The cylinder head is the upper section of the engine block that seals the combustion chamber, houses the valves, and provides the mounting surface for the fuel injector and related components. It works together with the head gasket to contain combustion pressure, ensuring the engine generates enough force to drive the vibratory mechanism on plate compactors or the drum drives on tandem rollers. When a cylinder head cracks, warps from overheating, or develops a failed sealing surface, the engine loses compression, consumes coolant or oil abnormally, and eventually cannot sustain operation — making prompt replacement essential to keeping these machines productive on site.
