The Wacker Neuson Cylinder Head Screw is a genuine OEM component designed for RD7 and RD10 series double drum rollers, including RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb, and RD10Yehf variants. Sourced directly from Wacker Neuson, this is the exact part specified for these machines — no substitution, no guesswork. It covers a broad range of LRC and HRC configurations across the RD7 family, making it a go-to fastener for technicians servicing multiple roller variants in their fleet. Keep part number on hand as a standard service item for any scheduled or unplanned engine head work on compatible Wacker Neuson rollers.
Key Features
- Correct Thread Engagement and Torque Integrity — Manufactured to OEM specification, this screw delivers the precise thread form and tensile rating required to maintain proper cylinder head clamping force on Wacker Neuson roller engines.
- Drop-In Engine Head Replacement — Matches the original fastener position, thread pitch, and drive spec exactly, allowing direct installation without modification during head removal or rebuild procedures.
- Wide RD7 and RD10 Series Coverage — A single part number covers LRC and HRC configurations across RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, and RD10Yehf variants, streamlining your parts inventory.
- Engine Sealing Performance — A correctly torqued cylinder head screw maintains the head gasket seal under compression and thermal cycling. A worn, stretched, or incorrect fastener risks head gasket failure, coolant or combustion gas loss, and engine damage.
- Combustion Integrity and Safety — Cylinder head fasteners are critical to maintaining compression and preventing hot gas escape. Using the correct OEM-grade screw ensures the head assembly meets the pressure containment requirements of the engine's design.
A cylinder head screw is a critical fastener that clamps the cylinder head tightly against the engine block, compressing the head gasket to form a sealed combustion chamber. It must withstand extreme heat, pressure, and vibration cycles without stretching or losing clamping load — if it does, the head gasket can fail, leading to compression loss, overheating, or internal engine damage. On compact double drum rollers like the RD7 and RD10 series, where the engine works hard in demanding compaction environments, using the correct replacement fastener during any head service is essential to restoring full engine integrity.
