The Wacker Neuson 5100021138 is a genuine OEM Left Rear Panel designed for the G-Series portable generator line, including G70, G95, G100, G110, G120, G130, and G150 models across Standard, Cold Weather, and Custom configurations. As a factory-sourced enclosure component, it matches the original dimensions and mounting geometry of the generator canopy. This panel is correct for Tier 3, Tier 4i, and Tier 4 Final emission-compliant variants, as well as select Canada Transport and switchable 600-volt configurations within the G-Series range.
Key Features
- Factory-Matched Enclosure Fit — Produced to original tooling specifications, ensuring the panel aligns flush with adjacent canopy sections and mounting hardware without adjustment.
- Genuine OEM Component — Sourced directly from Wacker Neuson, matching the original material gauge, finish, and formed profile of the production panel.
- Broad G-Series Compatibility — Confirmed fitment across G70, G95, G100, G110, G120, G130, and G150 generator models, spanning Tier 3, T4i, T4, T4F, Cold Weather, Standard, and Custom configurations.
- Structural Enclosure Integrity — A sound rear panel protects internal generator components from weather ingress, debris, and physical impact; a damaged or missing panel exposes the alternator and engine bay to conditions that accelerate wear and moisture damage.
- Correct Part for Regulated Markets — Applicable to Transport Canada, LATAM, and Brazil-market variants, ensuring replacement parts compliance across regulated regional configurations.
The left rear panel is a structural enclosure component that forms part of the generator's outer canopy shell. It shields internal components — including the engine, alternator, and control systems — from rain, dust, and job-site debris while also contributing to noise attenuation by sealing the enclosure. When a rear panel is cracked, bent, or missing, the generator's internal components are exposed to environmental damage and the canopy loses structural rigidity, which can allow vibration to stress surrounding fasteners and adjacent panels over time.
