The Wacker Neuson is a genuine OEM Cylinder Head Bolt designed for the RD7H series walk-behind tandem rollers and the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H series diesel reversible vibratory plate compactors. As a factory-sourced component, the is manufactured to the exact specification required for proper head sealing and engine integrity across all covered models. This part is a direct OEM replacement, meaning it matches the original in thread pitch, grade, and torque specification without any modification. Whether you are servicing an RD7H tandem roller or a DPU 5545H reversible plate, part number ensures the repair is completed to the original build standard.
Key Features
- OEM-Grade Fastener Material — Manufactured to the precise tensile strength and thread specification required to maintain correct cylinder head clamping force on the engine fitted to these machines.
- Drop-In Engine Replacement — Matches original thread dimensions and bolt length exactly, allowing installation directly into the existing cylinder head without reworking or adapting the bore.
- Broad Fitment Across Two Compaction Families — Covers the RD7H walk-behind tandem roller series and the DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H diesel reversible vibratory plate compactor series.
- Protects Engine Compression and Head Gasket Integrity — A correctly torqued, properly spec'd cylinder head bolt maintains the head gasket seal; a worn, stretched, or incorrect bolt risks coolant and compression loss, leading to engine damage.
- Critical Fuel and Compression Safety — Cylinder head fasteners are a safety-critical engine component; using the correct OEM-spec bolt ensures the combustion chamber remains sealed under operating pressures and temperatures.
A cylinder head bolt is a structural fastener that clamps the cylinder head tightly against the engine block, compressing the head gasket to form an airtight, liquid-tight seal around the combustion chamber and coolant passages. This seal is essential for maintaining correct compression, preventing exhaust gases from escaping, and stopping coolant or oil from entering the cylinder. When a cylinder head bolt stretches, corrodes, or fails to hold the specified torque — which can happen after repeated heat cycles or improper servicing — the head gasket seal is compromised, often resulting in loss of power, overheating, or internal fluid contamination that can cause serious engine damage.
