The Wacker Neuson Front Seal is a genuine OEM component designed for the LTW8K, LTW20Z1, and LTW20Z3 series light towers. As a direct factory replacement, it delivers the correct material grade and dimensional fit needed to maintain a proper seal in the mast or drive assembly. This part covers a broad range of LTW configurations including LED, Metal Halide, Cold Weather Tier 4, and custom Tier 4 variants. When it comes time to restore your light tower to proper operating condition, part number is the exact replacement Wacker Neuson specifies.
Key Features
- OEM-Grade Sealing Material — Manufactured to the same material and compression specification as the original, ensuring consistent sealing performance across temperature and load cycles typical of light tower operation.
- Drop-In Replacement Fit — Engineered to the original dimensional profile, so it seats correctly in the existing housing without reworking mating surfaces or surrounding components.
- Broad LTW Series Coverage — Confirmed fitment across LTW8K, LTW20Z1, and LTW20Z3 configurations, including LED, Metal Halide, Cold Weather Tier 4, and Custom Tier 4 variants.
- Prevents Fluid Loss and Contamination — A worn or compromised front seal allows lubricant to escape and contaminants to enter, accelerating wear on internal components. Replacing it promptly keeps the assembly protected.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 394173010 meets all original design requirements — no guesswork on compatibility or material grade.
A front seal serves as the primary barrier between a rotating or reciprocating shaft and the external environment, retaining lubricant inside the assembly while blocking dirt, moisture, and debris from working their way in. On a light tower like the LTW series, maintaining this seal is critical to protecting the mast drive or engine-adjacent components from premature wear. When the front seal deteriorates — through heat cycling, age, or mechanical wear — oil leaks and contamination can follow quickly, leading to accelerated internal damage if the seal is not replaced promptly.
