The Wacker Neuson Valve Stem Seal is a genuine OEM component designed for the LTN4Y and LTN5Y series light towers, including the LTN4Y, LTN4Y 60 Hz, LTN4Y SA, LTN4Y RH, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. As a genuine Wacker Neuson part, the is manufactured to the same material and dimensional standards as the original seal fitted at the factory, ensuring a drop-in fit with no guesswork. Replacing a worn or leaking valve stem seal promptly protects the engine from oil consumption issues and keeps the unit running at full efficiency across extended light tower deployments.
Key Features
- OEM-Grade Seal Material — Manufactured from the same compound and to the same compression tolerances as the original, ensuring consistent sealing performance under engine operating temperatures.
- Direct Drop-In Installation — Seats onto the valve stem the same way as the factory-installed seal, so there is nothing to modify or adapt during the replacement procedure.
- Broad LTN Series Coverage — Confirmed fit across the full LTN4Y and LTN5Y model families, including SA, RH, CH, UK, HD, 60 Hz, and 120V/60Hz variants.
- Prevents Oil Burning and Blow-By — A correctly functioning valve stem seal keeps engine oil out of the combustion chamber, preventing blue smoke, fouled plugs, and rising oil consumption during long runtime cycles.
- Sourced from Wacker Neuson — Carries the genuine Wacker Neuson part number 5100075760, so you can cross-reference with confidence and match exactly what the machine requires.
A valve stem seal sits at the base of each intake and exhaust valve guide, controlling the thin film of oil that lubricates the valve stem as it moves up and down. Its job is to allow just enough oil for lubrication while preventing excess oil from being drawn into the combustion chamber on the intake stroke. When the seal hardens, cracks, or wears out, oil begins slipping past the stem in uncontrolled amounts, leading to increased oil consumption, blue exhaust smoke at startup, and carbon buildup on the valve and piston crown. Replacing a failed seal restores the correct oil barrier and protects the engine from the cumulative damage that unchecked oil burning causes over time.
