The Wacker Neuson Cylinder Head Screw is a genuine OEM component designed for the LTN4Y, LTN5Y, and RD7H series light towers and rollers. As a direct OEM replacement, this screw is manufactured to the exact specification required by Wacker Neuson, ensuring correct thread engagement, torque retention, and sealing integrity at the cylinder head. Fitment extends across a broad range of LTN and RD7 variants — including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN5Y, LTN5Yp, LTN5Ypa, LTN5Ypk, LTN5Yp HD, RD7H, RD7Heh, RD7Hf, RD7Hehf, RD7Yeh, RD7Yehf, RD7Af, and their associated sub-variants — making part number a versatile stocking item for fleets operating multiple Wacker Neuson units.
Key Features
- OEM Thread and Torque Specification — Manufactured to exact Wacker Neuson tolerances for correct clamping load and secure cylinder head retention under operating pressures.
- Drop-In Replacement — Matches the original fastener's thread pitch, shank length, and head type, so it seats and torques into place exactly as the factory-installed screw did.
- Broad Fleet Coverage — Fits LTN4Y and LTN5Y light tower series as well as RD7H and RD7Yehf roller variants, covering one of Wacker Neuson's widest-used engine families.
- Critical Sealing Function — A correctly specified cylinder head screw maintains the compression seal between the head and block; an incorrect or worn fastener risks head gasket failure and compression loss.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number 5100006624 used in factory assembly and authorized service repair.
A cylinder head screw secures the cylinder head to the engine block, clamping the head gasket firmly between both surfaces to maintain a sealed combustion chamber. These fasteners must hold precise clamping force across a wide range of temperatures and pressures — if a screw stretches, strips, or loses torque retention, combustion gases can escape past the gasket, leading to power loss, overheating, or coolant contamination. Replacing a worn or damaged cylinder head screw with the correct OEM fastener restores the engineered clamping load and protects the integrity of the entire cylinder head assembly.
