The Wacker Neuson Cylinder Head Screw is a genuine OEM component designed for LTN4Y and LTN5Y light tower series as well as the RD7H roller series. As a direct OEM replacement sourced from Wacker Neuson, this screw is manufactured to the same specification as the original hardware installed at the factory. Fitment spans a wide range of configurations across the LTN4Y, LTN5Y, RD7H, and RD10 series, including standard, high-cycle, and special-application variants. Having the correct cylinder head screw on hand keeps engine service work moving without delays caused by incorrect hardware.
Key Features
- OEM Thread and Torque Specification — Manufactured to exact thread pitch and hardness grade required for cylinder head retention, ensuring proper clamp load and a leak-free head seal.
- Direct Drop-In Installation — Matches the original bolt pattern and head geometry, seating correctly into existing cylinder head bores without rework or thread chasing.
- Broad Series Fitment — Compatible with LTN4Y, LTN5Y, RD7H, and RD10Yehf series equipment across standard, 60 Hz, 120V, and special-application configurations.
- Engine Integrity Under Load — A correctly torqued cylinder head screw maintains combustion chamber compression and prevents head gasket failure during sustained operation.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized OEM component under part number 5100006626, verified for use across all listed models and build variants.
A cylinder head screw is a critical fastener that clamps the cylinder head firmly to the engine block, sealing the combustion chamber and maintaining the compression necessary for reliable engine operation. When these screws are worn, stretched, or incorrectly torqued, combustion gases can escape past the head gasket, leading to power loss, overheating, and potential engine damage. Replacing a cylinder head screw with the correct OEM-specified hardware ensures the head is held to the precise clamping load the engine was engineered to run with.
