Wacker Neuson 5000108504 Rebuild Kit, Internal Vibrator, Dia. 38

The Wacker Neuson is a genuine OEM Rebuild Kit, Internal Vibrator, Dia. 38, designed for the IRFU 38 and IRSE-FU 38 series 38 mm internal concrete vibrators. As a factory-sourced service kit, the delivers the exact components needed to restore a worn or underperforming vibrator head to original operating condition. This kit is confirmed compatible across a wide range of 38 mm inverter-driven vibrator models operating on 115 V, 120 V, and 230 V power configurations. Having this kit on hand keeps your concrete vibrator working through demanding pours without the cost of a full head replacement.

Key Features

• OEM-Matched Internal Components — Every part in this kit is manufactured to the same dimensional and material tolerances as the original vibrator head internals, ensuring correct bearing fit, seal compression, and eccentric weight clearance for the 38 mm needle diameter.
• Drop-In Service Fit — Engineered specifically for the 38 mm vibrator head housing used across the IRFU 38 and IRSE-FU 38 families, so the rebuild installs using standard service procedures with no sourcing of individual components separately.
• Broad IRFU 38 and IRSE-FU 38 Compatibility — Covers 115 V, 120 V, and 230 V variants across multiple cord lengths and regional configurations, including US, UK, CH, and WGB-spec models in both the IRFU and IRSE-FU 38 series.
• Restores Full Vibration Output — A worn or damaged vibrator head delivers inconsistent frequency and amplitude, leaving voids and honeycombing in concrete. This rebuild kit brings the head back to correct operating spec, ensuring thorough consolidation on every pour.
• Extend Service Life, Defer Replacement Cost — Rebuilding the head at the first sign of reduced output or bearing noise is significantly more economical than replacing the entire vibrator assembly, making this kit a practical part of a planned maintenance program.

The internal vibrator head is the working heart of a concrete vibrator — it houses the bearings, eccentric weight, and seals that generate the high-frequency vibration needed to consolidate freshly placed concrete. Over time, bearings wear, seals degrade, and the eccentric mechanism loses efficiency, resulting in reduced vibration amplitude, excessive heat, or complete head failure. The Wacker Neuson 5000108504 Rebuild Kit, Internal Vibrator, Dia. 38 provides the service components required to restore the 38 mm vibrator head to proper function, eliminating the vibration loss and potential concrete quality issues caused by a deteriorated head assembly.
