The Wacker Neuson Front Frame is a genuine OEM structural component designed for the HI 400HD G and HI 300HD D indirect-fired air heaters. As a direct factory replacement, this part matches the original specifications and mounting points of the machines it fits, ensuring a clean, accurate installation. Sourced directly from Wacker Neuson, part delivers the same material grade and dimensional accuracy as the frame installed at the factory. If your HI 400HD G or HI 300HD D heater has sustained frame damage or structural wear, this is the correct replacement to restore the unit to full operational condition.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original material and dimensional standards, maintaining the structural rigidity the heater chassis depends on.
- Direct Bolt-On Replacement — Matches all original mounting holes and attachment points on the HI 400HD G and HI 300HD D, allowing straightforward installation without rework or fabrication.
- Confirmed Fitment — Verified for HI 400HD G and HI 300HD D indirect-fired air heaters, covering both gasoline and diesel variants in this heater series.
- Protects Core Heater Components — The front frame provides the primary structural housing that shields internal combustion and heat-exchange components from impact and environmental exposure during operation and transport.
- Restore Full Unit Functionality — A damaged or distorted frame can misalign burner and airflow components; replacing it with the correct OEM part ensures all downstream components seat and operate as intended.
The front frame on an indirect-fired air heater serves as the primary structural chassis at the front of the unit, providing the mounting foundation for burner assemblies, air intake components, and protective covers. It holds critical internal parts in correct alignment so that combustion, heat exchange, and airflow all function within design parameters. When the front frame is bent, cracked, or corroded, component misalignment can disrupt airflow paths and burner positioning, reducing heating efficiency and potentially creating unsafe operating conditions.
