The Wacker Neuson 5100017961 Bush is a genuine OEM component designed for the FUflex4 series internal concrete vibrators, including the FUflex4/230, FUflex4/120, FUflex4/230 CH, and FUflex4/120 US models. Sourced directly from Wacker Neuson, this part meets the exact specifications required for proper function within the vibrator assembly. Confirmed fitment spans the full FUflex4 family, making it the correct choice whether you're servicing a 120V or 230V configuration.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact tolerances required for the FUflex4 vibrator assembly, ensuring correct seating and consistent contact with mating components.
- Drop-In Replacement — Installs directly into the FUflex4 housing without secondary machining or modification, restoring the assembly to original operating condition.
- Broad FUflex4 Family Coverage — Compatible with FUflex4/230, FUflex4/120, FUflex4/230 CH, and FUflex4/120 US variants, covering both North American and international voltage configurations.
- Supports Consistent Vibration Output — A worn or failed bush can introduce play into the vibrator shaft, degrading the amplitude and frequency needed for proper concrete consolidation; replacing it restores full performance.
- Backed by Wacker Neuson OEM Quality — Produced under Wacker Neuson's original manufacturing standards, so the part integrates reliably with existing FUflex4 components.
The bush in an internal concrete vibrator serves as a precision bearing surface that supports and guides the rotating or reciprocating shaft within the vibrator head or motor housing. It reduces friction between moving parts and maintains the correct alignment needed to deliver consistent vibration energy into concrete. When a bush wears, excessive play develops in the shaft, which can cause irregular vibration, accelerated wear on surrounding components, and ultimately a loss of effective concrete consolidation.
