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 part meets the exact specifications of the original hardware used in production — so you can install with confidence knowing it fits and functions as intended. Compatibility spans a wide range of LTN4Y and LTN5Y light tower variants, including the LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN5Yp, LTN5Ypa, LTN5Yp HD, LTN5Ypk, LTN5Y CH, LTN5Y UK, LTN5Y SA, and LTN4Y 120V/60Hz, as well as the RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Hfb, and RD7Hehfb. When you need the right fastener the first time, part number is the correct OEM choice.
Key Features
- Correct Thread Form and Torque Spec — As a genuine OEM fastener, the 5100006695 is manufactured to the precise thread pitch, grade, and dimensional tolerances required for cylinder head applications on Wacker Neuson engines.
- Drop-In Installation — Engineered to match the original bolt pattern and seating depth, this screw installs directly into the cylinder head without reworking threads or sourcing substitute hardware.
- Broad Series Compatibility — Fits LTN4Y and LTN5Y light tower series across multiple voltage and regional configurations, as well as RD7H series double-drum rollers — one part number covering a wide equipment footprint.
- Cylinder Sealing Integrity — A properly torqued cylinder head screw maintains the clamping force needed to keep the head gasket sealed under thermal cycling; worn, stretched, or incorrect fasteners can lead to compression loss and coolant or oil leaks.
- Genuine Wacker Neuson OEM Part — Supplied as original equipment hardware, not a substitute, ensuring the fastener's material grade and surface treatment match what was specified at the time of manufacture.
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. The clamping load it provides must remain consistent across temperature extremes — from cold starts to full operating heat — to prevent compression blowby, coolant ingestion, or oil migration. When a cylinder head screw stretches, corrodes, or is replaced with an incorrect grade, the clamping force becomes uneven, which can cause gasket failure and lead to costly engine damage if left unaddressed.
