The Wacker Neuson Rotary Shaft Seal is a genuine OEM component 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, LTN5Yp, LTN5Yp HD, LTN5Ypa, and LTN5Ypk models. Sourced directly from Wacker Neuson, this is a true OEM part — meaning it meets every dimensional and material requirement specified for the original build. If you're dealing with a leaking or worn seal on any of these light tower models, part number is the correct direct replacement. Count on an exact drop-in fit that restores your machine to proper operating condition without guesswork.
Key Features
- OEM Sealing Material Grade — Manufactured to the original compound and compression specification, ensuring the seal forms a proper, lasting barrier against fluid loss at the shaft interface.
- Direct Drop-In Replacement — Matches the original bore diameter, shaft diameter, and lip profile, so it seats correctly during installation without modification to the housing or shaft.
- Broad LTN Series Coverage — Fits the full LTN4Y and LTN5Y light tower families, including SA, RH, CH, UK, 60 Hz, 120V/60Hz, HD, pk, and pa variants — one part number covers a wide range of configurations.
- Protects Against Fluid Contamination — A correctly seated rotary shaft seal keeps lubricant in and dirt and moisture out; a failed seal can accelerate wear on bearings and internal components, leading to far more costly repairs.
- Genuine Wacker Neuson OEM Part — Carries the full Wacker Neuson OEM designation, giving you confidence the part was built and validated for this exact application rather than adapted from a generic alternative.
A rotary shaft seal is a precision ring fitted around a rotating shaft to prevent lubricating oil or grease from escaping the housing while also blocking external contaminants — dust, water, and debris — from entering. In a light tower application, the seal keeps the drivetrain or generator components properly lubricated under continuous operation. When a rotary shaft seal wears out or hardens with age, it begins to leak, starving internal components of lubrication and allowing contamination that accelerates wear — eventually leading to bearing failure or more extensive mechanical damage if left unaddressed.
