The Wacker Neuson Cylinder Head is a genuine OEM component designed for the RD7H series tandem rollers and DPU 4045H and DPU 5045H reversible vibratory plate compactors. As a direct OEM replacement, this cylinder head is sourced from Wacker Neuson and meets the same specifications as the original part installed at the factory. Fitment covers multiple configurations of the RD7H tandem roller family — including ES and S variants — as well as the full range of DPU 4045H and DPU 5045H diesel reversible plates across standard, AP, and EU configurations. When your machine is down, installing the correct part the first time keeps your crew and equipment on schedule.
Key Features
- Genuine OEM Combustion Integrity — manufactured to exact port geometry and deck surface tolerances required for proper compression and sealing in the engine cylinder assembly.
- Drop-In Engine Fitment — designed to align directly with the engine block, head gasket, and valve train components in the original mounting configuration, requiring no machining or adaptation.
- Broad Model Coverage — fits RD7H-ES, RD7H-S, and base RD7H tandem rollers, plus DPU 4045H and DPU 5045H diesel reversible vibratory plate compactors across multiple production variants.
- Sustained Engine Performance — a correctly seated cylinder head maintains combustion chamber pressure, ensuring the engine delivers consistent power output to the exciter system and drive components.
- Fuel and Exhaust Safety Compliance — proper cylinder head sealing prevents combustion gas leakage, protecting both the operator and surrounding components from heat damage and exhaust exposure.
The cylinder head is a core structural and functional component of a four-stroke engine. It sits atop the engine block, sealing the combustion chamber and housing the intake and exhaust valves, valve seats, and — in many configurations — the camshaft or rocker arm assembly. It works together with the head gasket to maintain compression, manage coolant and oil passages, and contain the heat generated during combustion. When a cylinder head cracks, warps, or develops a leak — often caused by overheating — the engine loses compression, may consume oil or coolant, and will eventually fail to start or run properly. Replacing a damaged cylinder head with a genuine OEM part restores correct compression and ensures all associated components seat and seal as originally engineered.
