The Wacker Neuson Spacer is a genuine OEM component designed for the IRFU58, IRFU65, IRflex58, IRflex60, IEC58, and FUflex4 series high-frequency internal concrete vibrators. Sourced directly from Wacker Neuson, this spacer meets the exact dimensional and material standards of the original part installed at the factory. Compatible across an extensive range of voltage configurations and cable lengths — including 5, 8, 10, and 15-meter variants — the covers a broad spread of IRFU, IRflex, IEC, and FUflex converter-integrated vibrator models. When you need a like-for-like replacement that drops straight into position without any guesswork, this is the correct part.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact tolerances, ensuring the spacer maintains correct clearances and alignment within the vibrator assembly.
- Direct Drop-In Replacement — Matches the original mounting position and interface, fitting seamlessly into the vibrator housing without reworking surrounding components.
- Broad Series Compatibility — Fits IRFU58, IRFU65, IRflex58, IRflex60, IEC58, and FUflex4 model families across 120 V and 230 V configurations, covering US, UK, CH, and GV market variants.
- Structural Integrity Maintained — A correctly fitted spacer keeps internal components properly separated and supported; a worn or missing spacer can cause contact, misalignment, and premature wear of adjacent parts.
- Verified OEM Part Number — Part number 5100005156 is confirmed against Wacker Neuson's official parts documentation, so you can order with confidence that this is the right component for your machine.
A spacer is a precision-machined component that maintains a set distance between two adjacent parts inside an assembly, preventing contact, controlling alignment, and distributing load evenly across the components it separates. In a high-frequency internal concrete vibrator, proper internal spacing is critical to keeping rotating and stationary elements in correct relationship with one another — misalignment caused by a worn or absent spacer can accelerate wear on surrounding parts and compromise vibrator performance. Replacing a damaged spacer promptly with the correct OEM part keeps the vibrator assembly operating as designed.
