The Wacker Neuson Valve Stem Seal is a genuine OEM valve stem seal designed for the LTN4Y and LTN5Y series light towers, including LTN4Y, LTN4Y RH, LTN4Y SA, LTN4Y 60 Hz, LTN4Y 120V/60Hz, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Ya, LTN5Yp, LTN5Yp HD, LTN5Ypk, and LTN4Y ME variants. As a genuine Wacker Neuson OEM part, the is manufactured to the exact material grade and dimensional tolerances of the original component — no guesswork on fit or compatibility. Sourcing the correct valve stem seal matters: an worn or deteriorated seal leads to oil burning, increased emissions, and long-term engine damage that far outweighs the cost of a straightforward seal replacement.
Key Features
- OEM-Grade Sealing Material — Manufactured from the same elastomer compound as the original, ensuring correct compression characteristics and resistance to heat and oil exposure in the engine valve train.
- Drop-In Replacement — Engineered to the exact dimensional profile of the original seal, seating correctly on the valve stem without modification during installation.
- Broad LTN Series Coverage — Fits the full LTN4Y and LTN5Y light tower family, including SA, RH, CH, UK, ME, 60 Hz, 120V/60Hz, HD, pk, and pa variants.
- Stops Oil Consumption at the Source — A correctly installed valve stem seal prevents engine oil from being drawn past the valve stem into the combustion chamber, keeping oil consumption in check and exhaust clean.
- Verified Wacker Neuson Part Number — Part number 5100075761 is confirmed against Wacker Neuson's OEM parts catalog, so you can order with confidence that you're receiving the correct component.
A valve stem seal fits around the stem of each intake and exhaust valve in the engine cylinder head, forming a controlled barrier between the lubricated valve guide and the combustion chamber. Its job is to allow just enough oil to lubricate the valve stem while preventing excess oil from being drawn into the combustion process. When a valve stem seal hardens, cracks, or loses its compression over time, oil migrates past the valve guide, burning in the cylinder and producing blue exhaust smoke — a reliable sign that the seal needs replacing. Addressing a failed valve stem seal promptly protects the engine from carbon buildup, fouled spark plugs, and accelerated internal wear.
