The Wacker Neuson L-Bolt is a genuine OEM fastener designed for the HI 770 XHD Indirect Air Heater series, including Arctic Bear XHD and Arctic Bear XHD NS configurations. As a direct OEM replacement, this L-Bolt is sourced from Wacker Neuson and built to the exact specifications required for secure, dependable service in demanding diesel-fired heating applications. It is confirmed compatible across multiple HI 770 XHD variants, covering both single-duct and dual-duct indirect heater builds. If you are servicing or reassembling a HI 770 XHD unit, verifying fitment with part number ensures you are installing the correct hardware.
Key Features
- Genuine OEM Hardware Integrity — Manufactured to Wacker Neuson's dimensional and material specifications, ensuring correct thread form, shank length, and bend geometry for this heater application.
- Drop-In Replacement — Engineered to install in the same location and orientation as the original, with no rework needed to existing mounting points or brackets.
- Broad HI 770 XHD Fitment — Compatible with Arctic Bear XHD, Arctic Bear XHD NS, and multiple HI 770 XHD indirect diesel air heater configurations across 1x16, 1x20, and 2x12 duct layouts.
- Structural Holding Power — The L-shaped profile provides a secure anchor point that resists pull-through and maintains clamping force under the vibration and thermal cycling typical of indirect-fired heater operation.
- Fuel and Heat System Safety — Correct fastener geometry and material grade are critical in heater assemblies where loose or incorrect hardware can compromise panel alignment, airflow seals, or burner enclosure integrity.
An L-Bolt is a threaded fastener with a right-angle bend at one end, used to anchor panels, brackets, or structural components that cannot be reached with a standard straight bolt. In the HI 770 XHD indirect air heater, this type of fastener secures key assembly points that must remain tight through repeated heat cycles, vibration from the diesel engine, and the mechanical stresses of transport and field deployment. When an L-Bolt becomes bent, corroded, or stripped, it can allow components to shift or loosen, potentially disrupting airflow paths or compromising the integrity of the heater enclosure.
