The Wacker Neuson Trailer Frame Complete is a genuine OEM structural assembly designed for HI750G and HI900DGM series indirect-fired air heaters. As a direct factory replacement, this complete frame unit restores the heater's tow-ready foundation exactly as originally built. Fitment covers the HI750G, HI750 DGM, HI900 DGM, and associated factory-installed option configurations. Sourcing the correct OEM frame ensures the heater unit, fuel tank, and hitch components all align and mount to the manufacturer's original specifications.
Key Features
- Genuine OEM Structural Integrity — Factory-sourced steel frame construction matches original wall thickness, weld points, and mounting geometry — critical for a load-bearing assembly that supports the full heater unit in transit.
- Complete Assembly, Ready to Install — Supplied as a full frame complete, so mounting brackets, attachment points, and hitch provisions are already integrated — no fabrication or adaptation needed.
- Confirmed Fitment for HI750G and HI900DGM Heaters — Verified for HI750G, HI750 DGM, HI900 DGM, and factory-installed option variants, covering the core indirect-fired heater lineup in this size class.
- Restores Safe Towing Capability — A cracked, bent, or corroded trailer frame compromises hitch security and heater stability during transport. Replacing with the OEM frame brings the unit back to its rated tow-ready condition.
- Tow Safety Compliance — For a trailered heater used on active worksites and public roads, a structurally sound frame is essential for DOT and jobsite towing compliance. Using the OEM replacement eliminates the uncertainty of fabricated repairs.
The trailer frame on an indirect-fired air heater serves as the structural backbone of the entire unit — it carries the heater body, fuel tank, and all ancillary components, and provides the hitch connection for towing between job locations. A damaged or deteriorated frame puts the whole assembly at risk during transport, and field-welded repairs may not restore the original load rating or hitch geometry. Replacing a worn or damaged frame with part number 5000186735 returns the HI750G or HI900DGM heater to its factory-engineered tow configuration, ensuring safe and compliant operation from site to site.
