The Wacker Neuson Washer is a genuine OEM component designed for the HI200D, HI200HD D, HI300D, HI300HD D, HI400HD G, and HI400HD D series indirect-fired air heaters. As a direct factory replacement, this washer is manufactured to the exact material and dimensional standards required by Wacker Neuson, ensuring a correct fit within the heater assembly. Genuine OEM sourcing means you receive the same part installed during original production — no guesswork on compatibility across the HI200, HI300, and HI400 heater families.
Key Features
- Genuine OEM Material Spec — Manufactured to Wacker Neuson's exact hardness and thickness tolerances, ensuring proper load distribution and sealing performance within the heater assembly.
- Drop-In Replacement — Matches the original mounting configuration on HI-series indirect air heaters, seating correctly against mating fasteners and surfaces without rework.
- Broad HI-Series Fitment — Confirmed for HI200D, HI200HD D, HI300D, HI300HD D, HI400HD G, and HI400HD D indirect air heaters, covering both diesel and gas variants across the lineup.
- Protects Fastener and Housing Integrity — A correctly spec'd washer distributes clamping load evenly, preventing fastener pull-through, housing deformation, or loosening under vibration and thermal cycling.
- Verified Part Number — Sourced directly under Wacker Neuson part number 5200011961, so you can cross-reference confidently against your machine's service documentation.
A washer may be a small component, but it plays a critical role in maintaining secure, properly loaded fastener connections throughout the heater's internal and external assemblies. In an indirect-fired air heater that operates under sustained heat output and vibration, washers that are worn, deformed, or the wrong thickness can allow fasteners to loosen over time — leading to structural movement, air leaks, or damage to surrounding components. Replacing a worn or missing washer with the correct OEM part restores the clamping integrity the assembly was engineered around.
