The Wacker Neuson Cylinder Head Screw is a genuine OEM cylinder head screw designed for the LTN4Y, LTN5Y, and RD7H series machines. Sourced directly from Wacker Neuson, this is the same part installed at the factory — ensuring correct thread pitch, shank dimensions, and torque characteristics for a secure cylinder head seal. Fitment extends across a wide range of LTN light tower models and RD7 series rollers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN5Y, LTN5Yp, LTN5Ypa, LTN5Y CH, LTN5Y UK, RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Af HRC, and related variants. When you order the, you are getting the exact OEM specification fastener your machine was built with.
Key Features
- OEM Thread and Torque Specification — Manufactured to Wacker Neuson's exact thread pitch and tensile grade, ensuring the cylinder head seats and seals correctly under operating pressure.
- Drop-In Installation — Matches the original hole pattern and head profile, so it installs directly into the existing cylinder head without chasing threads or modifying the bore.
- Broad Model Coverage — A single part number covers LTN4Y and LTN5Y light tower families as well as the RD7H and RD10 roller series, making it a versatile stock item for mixed fleets.
- Cylinder Seal Integrity — A correctly torqued cylinder head screw holds the head gasket under consistent clamping load; a worn or incorrect fastener allows compression loss and coolant or combustion gas leaks.
- Genuine Wacker Neuson OEM Part — Supplied through authorized Wacker Neuson distribution channels, so the part number, material grade, and surface treatment are verified against the original engineering specification.
A cylinder head screw is a high-tension fastener that clamps the cylinder head firmly against the engine block, compressing the head gasket to form a gas-tight and fluid-tight seal. It must maintain consistent clamping force across a wide range of operating temperatures and pressures — which is why thread form, tensile strength, and surface treatment all matter. When a cylinder head screw stretches, strips, or is replaced with an incorrect substitute, clamping load becomes uneven, leading to head gasket failure, compression loss, or coolant ingestion into the combustion chamber.
