The Wacker Neuson Cylinder Head is a genuine OEM component designed for the DPU 5045H and DPU 4045H reversible vibratory plate compactors. As a direct factory replacement, part is manufactured to the same specifications as the original, ensuring a correct fit within the engine assembly of these heavy-duty diesel compaction machines. This cylinder head is compatible across multiple DPU 5045H and DPU 4045H configurations, including the 50 kN, 45 cm reversible plate variants. When the original cylinder head is worn, cracked, or compromised, replacing it with the correct Wacker Neuson part restores full engine integrity and keeps your compactor running at peak output.
Key Features
- Genuine OEM Casting Integrity — Manufactured to exact Wacker Neuson specifications, ensuring proper combustion chamber geometry, valve seat alignment, and head gasket mating surface finish specific to this engine.
- Direct Engine Drop-In — Engineered to bolt directly onto the engine block of the DPU 5045H and DPU 4045H using the original fastener pattern and coolant/oil port locations — no reworking of mating surfaces required.
- DPU 5045H and DPU 4045H Fitment — Confirmed for multiple machine configurations within both model lines, covering the 50 kN reversible plate and the 750-series variants.
- Compression and Engine Output Restored — A compromised cylinder head causes compression loss, overheating, and reduced compaction force; this replacement brings combustion sealing back to spec so the plate delivers consistent centrifugal force.
- Fuel System and Emissions Compliance — Correct combustion chamber volume is critical for diesel fuel atomization and emissions performance; using the OEM cylinder head maintains the engine's designed air-fuel ratio and prevents excessive smoke or fuel consumption.
The cylinder head seals the top of the engine block, forming the upper boundary of the combustion chamber where fuel is ignited to drive the piston and generate power. It houses the intake and exhaust valve seats, and on many diesel engines it also contains the pre-combustion or direct injection passages that govern fuel delivery. When a cylinder head cracks, warps, or develops a compromised gasket surface, combustion pressure escapes, leading to power loss, overheating, coolant contamination, and ultimately engine failure. On a reversible vibratory plate like the DPU series, consistent engine output directly determines compaction force — so a damaged cylinder head doesn't just affect the engine, it undermines the machine's entire compaction performance on site.
