The Wacker Neuson Cylinder Head Screw is a genuine OEM component designed for the RD7 and RD10 series double drum rollers, including RD7H, RD7Heh, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, and RD10Yehf model variants. As a factory-sourced part, it meets the exact specifications set for the original engine assembly, ensuring correct torque retention and a secure cylinder head seal. Wacker Neuson covers a broad range of HRC and LRC configurations across both the RD7 and RD10 families, making it a widely applicable service part for fleets running these machines. Verify your model number before ordering to confirm fitment.
Key Features
- Correct Thread Engagement and Torque Spec — Manufactured to OEM dimensions, this cylinder head screw delivers the precise thread engagement and clamping force needed to maintain a proper head seal under operating load.
- Direct Drop-In Replacement — Engineered to seat and torque exactly as the original, with no reworking of the cylinder head or fastener bore required during installation.
- Broad RD7 and RD10 Series Coverage — A single part number that fits RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Yeh, RD7Yehf, RD7Af, and RD10Yehf variants in both HRC and LRC configurations.
- Combustion Integrity Maintained — A correctly torqued cylinder head screw holds head gasket compression, preventing compression loss, coolant leaks, and power drop that result from a failed or stretched fastener.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you get the same fastener grade and specification as the original build — not a generic substitute.
- Critical Fastener — Correct Spec Matters — Cylinder head screws operate under high thermal and mechanical stress; using a correctly rated OEM fastener reduces the risk of fastener fatigue, head warping, or gasket failure during operation.
A cylinder head screw is a critical engine fastener that clamps the cylinder head firmly against the engine block, compressing the head gasket to create an airtight and liquid-tight seal within the combustion chamber. Without the correct clamping force — achieved only when the right-specification screw is torqued to the proper value — combustion pressure can escape, coolant can leak into the cylinder, and engine performance drops rapidly. When a cylinder head screw stretches, corrodes, or breaks, it must be replaced with an exact-spec fastener to restore the integrity of the engine assembly and prevent further damage to the head or block.
