The Wacker Neuson Rear Seal is a genuine OEM component designed for the LTW8K, LTW20Z1, and LTW20Z3 series light towers. Sourced directly from Wacker Neuson, this seal meets the exact material and dimensional specifications of the original part. It is compatible across a broad range of LTW configurations, including LED, Metal Halide, Cold Weather Tier 4, and Custom Tier 4 variants. If you're servicing or rebuilding the engine or drivetrain on your light tower, part number is the correct replacement to restore a proper seal.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original compound and compression specification, ensuring the seal performs at the correct interference fit and resists oil leakage under operating temperatures typical of LTW light tower engines.
- Direct Drop-In Replacement — Matches the original rear seal profile exactly, allowing installation without machining or modification to the housing bore.
- Broad LTW Series Fitment — Confirmed compatible with the LTW8K, LTW20Z1, and LTW20Z3 families across multiple configurations, including Cold Weather T4, Custom T4, LED, and MH variants.
- Prevents Oil Loss and Contamination — A failed or worn rear seal allows engine oil to escape at the crankshaft exit point, leading to oil loss, environmental contamination, and accelerated bearing wear if left unaddressed.
- Genuine OEM Part — Part number 5200005519 is sourced from Wacker Neuson's authorized parts supply chain, providing full confidence in specification accuracy and part authenticity.
A rear seal is positioned at the back of the engine crankshaft and prevents engine oil from leaking past the rotating shaft where it exits the block. It works under continuous rotational load and must maintain a tight, consistent seal against the crankshaft surface to keep oil inside the engine. When a rear seal wears out or hardens with age, oil will begin to seep out at the rear of the engine — a leak that can worsen quickly if the machine continues to operate. Replacing the rear seal at the first sign of leakage protects the engine from oil starvation and keeps the light tower running cleanly on the jobsite.
