- Genuine Wacker Neuson Part — Sourced directly through the authorized Wacker Neuson parts supply chain, carrying part number 5100006677 for straightforward ordering and inventory verification.
A cylinder head screw is a critical fastener that clamps the cylinder head firmly against the engine block, maintaining the compression seal created by the head gasket. Without the correct clamping load — delivered only when the right fastener is installed and torqued to specification — combustion gases can escape past the gasket, leading to power loss, overheating, or serious engine damage. On compact double drum rollers like the RD7 series, where the engine works hard in demanding compaction applications, a worn, stretched, or incorrect cylinder head screw can accelerate these failures and take the machine out of service at the worst possible time.
