The Wacker Neuson Cover is a genuine OEM component designed for the HI-series indirect-fired air heaters, including the HI 110D, HI 110HD D, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, and HI 400HD G models, as well as the HDR 155 direct-fired radiant heater. Sourced directly from Wacker Neuson, this cover matches the original part in material, fit, and function — no guesswork, no adaptation. It is the same cover installed at the factory, ensuring your heater maintains its intended structural integrity and operational performance. If you are servicing a diesel or gas indirect air heater in the HI lineup, part number is the correct OEM replacement to restore it to original condition.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the cover seats and fastens exactly as the original did from the factory floor.
- Direct Bolt-On Replacement: — Matches the original mounting points and panel geometry of the covered HI-series and HDR 155 heater housings for a clean, straight swap during service.
- Broad HI-Series Compatibility: — Fits a wide range of Wacker Neuson indirect air heaters including the HI 110D, HI 200D, HI 300HD D, HI 400HD D, HI 400HD G, and HDR 155, covering both diesel and gas variants.
- Protects Internal Heater Components: — A properly fitted cover shields burner assemblies, heat exchangers, and fuel system components from jobsite debris, moisture, and physical damage that can shorten heater service life.
- Verified Part Number Integrity: — Part number 5000183971 cross-references directly to multiple HI-series machine numbers, giving you confidence you are ordering the right cover for your specific heater configuration.
The cover on an indirect-fired air heater serves as the outer protective enclosure for the unit's internal components — including the burner, heat exchanger, and airflow components. It keeps water, debris, and physical impacts away from sensitive internal systems that would otherwise be exposed during transport, storage, or operation on an active jobsite. When a cover is cracked, missing, or improperly seated, internal components become vulnerable to contamination and damage, which can lead to reduced heating efficiency, fuel system issues, or premature component failure. Replacing a damaged cover with the correct OEM part restores the heater's protective envelope and keeps it operating as intended through demanding cold-weather applications.
