The Wacker Neuson is a genuine OEM Washer 1/4 designed for the full range of Wacker Neuson G-Series skid-mounted and mobile generators, spanning the G25, G50, G70, G85, G120, G125, G150, G180, G230, G240, and G320 families, as well as select HI-Series indirect-fired air heaters and MGT mobile generator trailers. Sourced directly from Wacker Neuson, this washer meets the exact material and dimensional standards set for your machine. Whether you are performing scheduled maintenance or rebuilding a fastened assembly, using the correct OEM hardware ensures the joint holds to spec. Cross-reference part number against your machine's serial number and model before ordering to confirm fitment for your specific configuration.
Key Features
- OEM-Spec Material and Sizing — Manufactured to Wacker Neuson's exact 1/4-inch dimensional standard, ensuring correct load distribution and clamping force across the fastened joint.
- Drop-In Hardware Replacement — Matches the original washer profile precisely, so it seats flush against mating surfaces without shimming or modification.
- Broad G-Series Generator Coverage — Confirmed fitment across G25, G50, G70, G85, G120, G125, G150, G180, G230, G240, and G320 mobile generator families, plus select HI-Series heater and MGT trailer assemblies.
- Protects Fastened Assemblies — A correctly sized washer spreads clamping load evenly, preventing fastener pull-through, surface damage, and joint loosening under vibration — all common failure points on mobile power equipment.
- Genuine Wacker Neuson Part — Supplied as authentic OEM hardware, giving you confidence that the replacement part matches the original specification your equipment was built with.
A washer serves as a load-distribution interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading clamping force over a wider area, it prevents the fastener head from pulling into or damaging softer materials, and it helps maintain consistent joint tension even when the assembly is subject to vibration or dynamic loads. On mobile generators and associated equipment, where engine vibration and frequent transport cycles are constant factors, undersized, worn, or missing washers can allow fastener joints to work loose over time, leading to misaligned components or structural damage. Replacing a worn washer with the correct OEM part restores proper clamping geometry and keeps critical assemblies secure throughout the service interval.
