The Wacker Neuson Flat Washer is a genuine OEM component designed for HI 770 XHD indirect-fired diesel air heaters and LTN6K-V, LTN6L-V, and LTN8K-V series light towers. Sourced directly from Wacker Neuson, this flat washer matches the original specification used on the production line, ensuring correct load distribution and fastener retention across every compatible application. The covers a broad range of HI and LTN configurations including cold-weather, custom, and Tier 4 Final variants, making it a versatile stocking part for fleet operators and service technicians alike.
Key Features
- Genuine OEM Load Distribution — Manufactured to the exact bearing-surface dimensions specified by Wacker Neuson, ensuring consistent clamping force without fastener pull-through or surface damage.
- Direct Drop-In Installation — Matches the original hole diameter and outer profile, so it seats correctly in the existing fastener stack without shimming or adjustment.
- Broad Fitment Across HI and LTN Families — Compatible with HI 770 XHD indirect air heaters and LTN6K-V, LTN6L-V, and LTN8K-V light towers, including Tier 4 Final, cold-weather, and custom configurations.
- Protects Mating Surfaces — Distributes fastener load evenly across the joint, preventing surface deformation or loosening under vibration — a common failure point on diesel-powered equipment in demanding field conditions.
- Verified OEM Part Number — Ordering by Wacker Neuson part number 5000178719 confirms you receive the correct washer grade and sizing for your specific machine configuration.
A flat washer sits between a fastener head or nut and the surface being clamped, spreading the load over a wider area to prevent the fastener from pulling through or damaging softer or thinner materials. On equipment like light towers and indirect air heaters — where vibration from diesel engines is constant — washers play a critical role in keeping assemblies tight and protecting mounting surfaces over time. A missing, wrong-sized, or worn flat washer can lead to fastener loosening, surface damage, and eventual component failure at the joint.
