Wacker Neuson 5000124789 Rebuild Kit Internal Vibrator GV Diameter 45

The Wacker Neuson Rebuild Kit Internal Vibrator GV Diameter 45 is a genuine OEM service kit designed for IRFUN 45 and IRFU 45 series internal concrete vibrators. This kit delivers everything needed to restore a worn or damaged 45 mm GV vibrator head back to operating condition, covering the IRFUN 45/115 GV, IRFUN 45 GV, IRFU 45/120 GV GB, and IRFU 45/230/5 GV models. As a genuine Wacker Neuson part, is produced to the same standards as the original components installed at the factory, so you know the rebuilt unit will perform exactly as intended. Keep this kit on hand whenever you're running 45 mm GV vibrator heads on concrete pours to avoid extended delays between repairs.

Key Features

• Genuine OEM Component Matching: — Each part in this rebuild kit is manufactured to the same material and dimensional specifications as the original vibrator head internals, ensuring consistent vibration output and service life after the rebuild.
• Complete Head Rebuild in One Kit: — Bundles the internal components required to fully service the 45 mm GV vibrator head, eliminating the need to source individual pieces separately.
• Broad IRFUN 45 and IRFU 45 Series Coverage: — Confirmed fitment across IRFUN 45/115 GV (including 8 m and 10 m cable variants), IRFUN 45 GV, IRFU 45/120 GV GB, and IRFU 45/230/5 GV models.
• Restored Vibration Frequency and Amplitude: — Worn internal components cause inconsistent vibration, leading to poor concrete consolidation and voids. A correctly rebuilt head delivers the steady, even vibration needed for properly consolidated pours.
• Electrical Safety Assurance: — Internal vibrators operate in wet concrete environments; using genuine OEM internal components maintains the insulation integrity and mechanical tolerances that protect the converter and operator during use.

The internal vibrator head is the working end of a high-frequency concrete vibrator system — it is inserted directly into fresh concrete to consolidate the mix by eliminating trapped air pockets and ensuring even distribution around reinforcement. The 45 mm GV head operates at high frequency driven by an integrated or external converter, and its internal components — including eccentric weights, bearings, and seals — are subject to continuous mechanical stress and exposure to abrasive slurry. When these components wear, vibration output drops or becomes erratic, resulting in poorly consolidated concrete that may contain voids or honeycombing. Rebuilding the head with the correct OEM kit restores the vibrator to full operating specification and extends the service life of the overall unit.
