The Wacker Neuson Flat Washer is a genuine OEM component designed for the E3000 and E5000 Hydronic Surface Heater and Ground Heater series, as well as the HI770XHD Indirect Air Heater line. As a direct OEM replacement, part is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct load distribution and secure fastening wherever it is used in the assembly. This washer fits across a wide range of E3000, E3000 ES, E5000, S3000, and HI770XHD configurations, making it a versatile service item to keep on hand for seasonal heating equipment maintenance.
Key Features
- Genuine OEM Hardware Grade — Correct material thickness and bore diameter match the original fastener assembly, maintaining proper clamp load without distortion under thermal cycling.
- Drop-In Service Replacement — Installs directly in place of the original washer with no modification to surrounding hardware or fasteners.
- Broad Heating Equipment Fitment — Confirmed for E3000 and E3000 ES Ground Heater and Hydronic Surface Heater variants, E5000 Ground Heaters, S3000 Hydronic Surface Heaters, and HI770XHD Indirect Air Heater models.
- Protects Mating Surfaces — Distributes fastener load evenly across the contact surface, preventing pull-through, surface damage, and loosening caused by vibration or thermal expansion.
- Part Number Verified — Order with confidence using Wacker Neuson part number 5000167732 to confirm you receive the correct washer for your specific machine configuration.
A flat washer serves as a load-distribution interface between a fastener — such as a bolt or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener head from embedding into or damaging the mating material, and it helps maintain consistent clamping tension over time. In heating equipment like the E3000 Ground Heater or HI770XHD Indirect Air Heater, where components experience repeated thermal expansion and contraction through seasonal use, a worn, deformed, or missing washer can lead to loosened fasteners, surface damage, and potential assembly failure during operation.
