The Wacker Neuson 5100021139 is a genuine OEM Right Rear Panel designed for the G95, G100, G110, and G120 series portable generators. As a direct OEM replacement, part 5100021139 is manufactured to the exact specifications of the original component, ensuring a proper fit across the full range of covered generator configurations — including standard, cold weather, skid-mounted, custom, and Tier 4i variants. This panel covers an extensive fitment list spanning multiple production runs of the G100 and G120, as well as select G95 and G110 models built for North American, Canadian, and international markets.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original tooling specs, ensuring the panel profile, mounting points, and material thickness match what came off the line.
- Broad Generator Series Coverage — Fits G95, G100, G110, and G120 portable generator configurations, including standard, cold weather, skid-mounted, custom, Tier 3, and Tier 4i variants.
- Direct Bolt-On Replacement — Mounting hardware locations align with the original frame, allowing straightforward panel swap without cutting, drilling, or custom fitting.
- Structural Enclosure Integrity — Restores the generator's weather and impact resistance at the rear quarter, protecting internal components from exposure on the worksite.
- Multi-Market Fitment — Covers units built for US, Canadian (Transport Canada), Brazilian, and Latin American markets across multiple model years.
The right rear panel is a structural enclosure component that forms part of the generator's outer housing. It protects internal components — including the engine, alternator, and wiring — from weather, debris, and accidental contact during operation and transport. A damaged or missing rear panel leaves critical internals exposed to moisture and physical damage, which can accelerate component wear and create safety hazards for operators working around the unit.
