The Wacker Neuson 5100022738 is a genuine OEM Rear Duct (Black) designed for the G70 and G100 series portable generators. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed on your machine. Fitment covers a wide range of G70 and G100 configurations, including Standard, Cold Weather, Custom, and URI HVAC variants across T4 and T4F emission tiers. Confirm your model and machine number before ordering to ensure a correct match.
Key Features
- Genuine OEM Construction: — Molded to the original material grade and profile, ensuring the duct maintains correct airflow geometry through the generator enclosure.
- Direct-Fit Replacement: — Engineered to the same mounting points and panel cutouts as the original, allowing the duct to seat and secure without modification.
- Broad G-Series Compatibility: — Covers G70 and G100 generator models across Standard, Cold Weather, Custom, URI HVAC, and URI CW configurations in both T4 and T4F tiers.
- Cooling Airflow Integrity: — A correctly fitted rear duct channels exhaust air out of the enclosure as designed; a cracked, warped, or missing duct can allow hot air recirculation, raising operating temperatures and stressing engine and alternator components.
- OEM Part Number Verified: — Listed under Wacker Neuson part number 5100022738 for straightforward cross-referencing against your parts manual or service documentation.
The rear duct on a Wacker Neuson portable generator is a formed air-management component that directs cooling and exhaust airflow through and out of the generator enclosure. By routing hot air away from the engine and alternator, it prevents heat buildup that can degrade electrical output quality and shorten the service life of internal components. When the duct becomes cracked, discolored, or damaged, airflow paths are disrupted, which can cause the unit to run hotter than designed and trigger thermal protection shutdowns under load.
