The Wacker Neuson Washer is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 series heaters. As a factory-sourced part, it meets the exact specifications Wacker Neuson set during original production, ensuring it seats, loads, and functions correctly within the assembly. This washer is a direct replacement for worn or damaged hardware on compatible HDR series units, keeping critical fastened connections properly clamped and aligned.
Key Features
- Genuine OEM Material Grade — Manufactured to the precise thickness, hardness, and load-distribution specification Wacker Neuson requires for this heater application, preventing fastener loosening under thermal cycling.
- Drop-In Hardware Fit — Matches the exact bore diameter and outer profile of the original, so it installs without any rework to mating hardware or fasteners.
- HDR Series Compatibility — Confirmed fitment for the HDR 155 Direct Fired Radiant Heater and the HDR 45, covering both common models in the HDR direct-fired radiant heater family.
- Protects Clamped Surfaces — Distributes fastener load evenly across the mating surface, preventing crushing or distortion of heater components that can result from an undersized or worn washer.
- Sourced Direct from Wacker Neuson — Carries the correct OEM part number 5200011775, so you can cross-reference confidently against your machine's parts diagram before ordering.
A washer serves a straightforward but important role in any bolted assembly — it spreads the clamping force of a fastener over a wider surface area, protecting the material beneath and maintaining consistent tension in the joint. In a direct-fired radiant heater like the HDR 155 or HDR 45, connections are subjected to heat, vibration, and repeated thermal expansion and contraction. A washer that is worn, deformed, or the wrong specification can allow fasteners to work loose over time, leading to component movement, air or fuel system leaks, or structural damage to the heater housing. Using the correct OEM washer ensures the joint maintains its rated clamping force throughout the service life of the machine.
