The Wacker Neuson is a genuine OEM External Tooth Washer #10 designed for the G25, G50, and G70 series skid-mounted mobile generators. As a factory-sourced component, this washer is produced to the exact material and dimensional specifications used during original assembly, ensuring a correct, consistent fit within the generator's fastening points. Compatibility covers both standard and cold-weather generator configurations across the G25, G50, and G70 model lines. When you need a verified OEM replacement you can install with confidence, is the correct part.
Key Features
- Genuine OEM Material Grade — Sourced directly from Wacker Neuson, this washer meets the exact hardness and tooth geometry specifications used in original assembly — critical for maintaining proper clamping force without loosening under vibration.
- External Tooth Design for Vibration Resistance — The serrated outer teeth bite into mating surfaces to resist rotational loosening, a key requirement in generator applications where engine vibration is constant.
- Broad G-Series Generator Coverage — Fits G25, G50, and G70 skid-mounted mobile generators in both standard and cold-weather configurations, covering a wide range of Wacker Neuson portable power equipment.
- Drop-In Replacement — Matches the original #10 sizing exactly, slipping onto fastener shanks without modification and seating flush against mating hardware just as the factory-installed part does.
- Fastener Integrity Under Load — A worn or undersized washer can allow fasteners to back out or lose torque over time; using the correct OEM specification washer maintains joint integrity across extended operating cycles.
An external tooth washer is a locking washer with serrations around its outer circumference that dig into both the fastener head and the mating surface when a bolt or screw is tightened. This mechanical grip prevents the fastener from backing out due to vibration or cyclic loading — a common cause of loose hardware in generator enclosures and mounting assemblies. When a washer loses its tooth profile through wear, corrosion, or reuse, its locking effectiveness drops significantly, which can lead to loose fasteners, increased vibration transfer, and potential structural or electrical connection issues within the generator.
