The Wacker Neuson Cylinder Head Screw is a genuine OEM cylinder head screw designed for the RD7H, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, RD7Hfb, RD7Hehfb, RD7Yehfb, RD7Afb, and RD10Yehf series double drum rollers. As a factory-sourced component, this screw is produced to the exact specifications required by Wacker Neuson for correct cylinder head clamping and sealing. Part number covers a broad range of RD7 and RD10 series variants — including LRC and HRC configurations — making it a highly versatile fastener for fleet operators and service technicians who maintain multiple machines. Confirm your model number against the fitment list before ordering to ensure a direct, correct-spec replacement.
Key Features
- OEM Clamping Specification: — Manufactured to Wacker Neuson's exact torque and thread specification, ensuring proper cylinder head clamping load and a secure, leak-free seal.
- Direct Drop-In Installation: — Matches the original thread pitch, shank diameter, and head profile, allowing straightforward installation without reworking threaded bores or sourcing additional hardware.
- Broad RD7 and RD10 Series Coverage: — A single part number serves LRC and HRC variants across the RD7H, RD7Yeh, RD7Af, RD7Hf, RD7Hehf, RD7Yehf, and RD10Yehf series, simplifying parts inventory for multi-unit fleets.
- Head Integrity Protection: — A correctly torqued cylinder head screw maintains combustion chamber compression and prevents coolant or oil ingress; a worn, stretched, or incorrectly spec'd fastener risks head gasket failure and engine damage.
- Genuine OEM Sourcing: — Supplied directly from Wacker Neuson's parts network, so the metallurgy, thread form, and surface treatment meet the same standards as the screw installed at the factory.
A cylinder head screw is a critical fastener that clamps the cylinder head firmly against the engine block, compressing the head gasket to form a sealed combustion chamber. By maintaining the precise clamping force specified by the engine manufacturer, these screws ensure that combustion pressure, oil, and coolant all remain in their designated passages. When a cylinder head screw stretches, corrodes, or is replaced with an incorrect-spec fastener, the clamping load drops — leading to head gasket failure, compression loss, overheating, and potential engine damage that far outweighs the cost of using the correct OEM part from the start.
