The Wacker Neuson Washer 9 Tapered is a genuine OEM component designed for the A3000, B3000, B5000, X3000, A5000, and D4000 internal vibrator power units, the E2200 ground heater, and the GS5.5A portable generator. As a direct Wacker Neuson OEM part, the is manufactured to the exact geometry and material specification of the original, ensuring correct seating and clamping load wherever it is installed. This tapered washer is a small but critical fastening component — using the correct part maintains proper joint integrity across the assemblies it serves. Confirm your model number against the fitment list before ordering to ensure this is the right washer for your machine.
Key Features
- Exact OEM Taper Geometry — Manufactured to the precise taper angle of the original, ensuring correct load distribution and consistent clamping force at the fastener joint.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson as an authorized OEM component, identical in material grade and dimensional spec to what left the factory.
- Broad Model Coverage — Fits A3000, B3000, B5000, X3000, A5000, and D4000 gasoline and diesel internal vibrator power units, the E2200 ground heater, and the GS5.5A 50Hz portable generator.
- Maintains Joint Integrity — A correctly fitted tapered washer prevents fastener loosening under vibration and load — critical on equipment that runs with sustained mechanical vibration.
- Drop-In Replacement — Installs in the same position as the original with no modification to surrounding hardware, keeping your service time short.
A tapered washer is designed to compensate for angled or uneven mating surfaces, distributing the clamping load of a fastener evenly across the joint. Without the correct taper profile, a standard flat washer would rock on the surface, concentrating stress at one edge and leading to fastener loosening or joint failure — particularly problematic on vibrating equipment such as internal vibrator power units and portable generators. Using the correct OEM-spec tapered washer restores the fastener assembly to its intended clamping geometry and helps prevent recurring loosening during operation.
