Wacker Neuson 5000029771 Eccentric Shaft Internal Vibrator

The Wacker Neuson is a genuine OEM Eccentric Shaft Internal Vibrator designed for Wacker Neuson internal concrete vibrator heads and drive units. As a direct OEM replacement, this part is manufactured to the exact tolerances required to restore proper vibration output in the vibrator head assembly. It fits a wide range of Wacker Neuson internal vibrator models including the A5000/160, A5000/160B, L5000/225, M2500/120, and M2500/230 series across ISO, ANSI, and GB configurations. When you need to return a vibrator head to full working condition, part is the correct factory-sourced component for the job.

Key Features

• Genuine OEM Eccentric Mass Tolerancing — Manufactured to Wacker Neuson's exact eccentricity specifications, ensuring the shaft delivers the correct centrifugal force and vibration amplitude for effective concrete consolidation.
• Drop-In Shaft Replacement — Engineered to the original shaft dimensions so it installs directly into the vibrator head housing without modification to bearings, couplings, or the drive hose connection.
• Broad Model Coverage — A single part number covers A5000/160 (ISO, ANSI, and B variants), L5000/225 (ISO and ANSI), M2500/120, M2500/230, and H65 vibrator head applications.
• Restores Full Vibration Output — A worn or damaged eccentric shaft reduces vibration frequency and amplitude, leaving concrete under-consolidated. Replacing it with 5000029771 brings the head back to rated performance.
• Sourced Direct from Wacker Neuson — Backed by the OEM parts program, this shaft meets the same material and balance standards as the original component installed at the factory.

The eccentric shaft is the core rotating component inside an internal concrete vibrator head. As it spins at high speed, its off-center mass generates the centrifugal force that causes the vibrator head to oscillate, driving air bubbles out of fresh concrete and consolidating the mix around rebar and formwork. If the eccentric shaft wears, bends, or becomes damaged, vibration output drops or stops entirely, resulting in honeycombing, voids, and weakened concrete structures. Replacing the shaft promptly with a correctly spec'd part like the Wacker Neuson 5000029771 restores the vibrator head to full operational condition and protects the integrity of the pour.
