The Wacker Neuson Cover is a genuine OEM component designed for the HI 770 XHD series indirect-fired diesel air heaters, including Arctic Bear XHD and Arctic Bear XHD NS configurations. Sourced directly from Wacker Neuson, this cover is built to the same specifications as the original part it replaces, ensuring a proper fit across the full range of HI 770 XHD machine variants. Whether you're servicing a 1x16, 1x20, or 2x12 ducting configuration, part number is the correct factory replacement. Keep your heating equipment protected and performing through demanding cold-weather jobsite conditions.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional standards, ensuring the cover seats, seals, and protects exactly as the original did from day one.
- Direct Bolt-On Replacement: — Designed to install in the same position and orientation as the factory cover, with no reworking of mounting points or surrounding components.
- Broad HI 770 XHD Compatibility: — Fits Arctic Bear XHD, Arctic Bear XHD NS, and standard HI 770 XHD indirect-fired diesel air heater models across multiple ducting configurations (1x16, 1x20, 2x12).
- Protects Critical Internal Components: — A properly fitted cover shields the heater's internal combustion and airflow components from exposure, debris ingress, and physical damage during transport and operation.
- Verified Part Number: — Part 5000166728 is the correct OEM reference for all listed HI 770 XHD machine numbers, giving you confidence you're ordering the right part before it ships.
The cover on an indirect-fired air heater serves as a protective enclosure for the unit's internal components, shielding the combustion chamber, heat exchanger, and airflow passages from environmental exposure, physical impact, and debris. On diesel indirect heaters like the HI 770 XHD, which are routinely deployed in harsh cold-weather conditions, a damaged or missing cover can allow moisture, dust, and contaminants to compromise sensitive components, leading to reduced heating efficiency or premature component wear. Replacing a cracked, warped, or damaged cover promptly helps maintain the integrity of the heater and keeps it operating safely at full output.
