Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to exact original tolerances, ensuring the plate seats and mounts correctly without rework or shimming.
- Direct Drop-In Replacement — Matches the original mounting geometry and hole pattern, so installation follows the same procedure as the factory-fitted part.
- Broad Heater Compatibility — Fits HI 90, HI 120, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HDR 45, HDR 155, and HD 70 heaters across the Wacker Neuson portable heating range.
- Structural Integrity for Heating Components — A correctly fitted support plate keeps internal heater components properly positioned under operating loads; a worn or damaged plate can allow movement that leads to misalignment and premature wear of adjacent parts.
- Verified Part Number — Ordering by OEM part number 5200021229 eliminates guesswork and reduces the risk of receiving an incompatible part for your heater model.
A support plate provides the structural foundation that holds internal heater components in their correct operating position. In portable indirect and direct-fired heaters, this plate absorbs vibration and mechanical load during operation, preventing movement that could stress mounting hardware or cause component misalignment. When a support plate becomes cracked, deformed, or worn, it compromises the stability of the assembly it carries — leading to increased vibration, accelerated wear on surrounding components, and potential operational faults in the heater.
