The Wacker Neuson Friction Spring is a genuine OEM component designed for BV50A-P and BV50A-H series backpack concrete vibrators. As a direct OEM part, the is manufactured to the same specifications as the original, ensuring a drop-in fit with no guesswork. This spring supports correct engagement and controlled slip within the drive system, making it a critical wear item for operators who depend on consistent vibrator performance on the pour. Confirm your model number against the fitment list before ordering — this part covers multiple BV50A-P and BV50A-H configurations.
Key Features
- Correct Spring Tension for Friction Drive Systems — Manufactured to OEM tension tolerances, so the friction interface engages and releases at the right load — not too stiff, not too soft.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000217222 carries the same part specification as the component that left the factory originally.
- Fits Multiple BV50A Backpack Vibrator Configurations — Compatible across BV50A-P and BV50A-H series models, including SPM4+PH45 and SPM2+PH45 backpack variants.
- Restores Smooth Power Transfer to the Vibrator Head — A worn or fatigued friction spring causes inconsistent vibration output or slippage under load; replacing it brings the drive back to spec.
- Direct Replacement with No Adaptation Needed — Designed as an exact fit for the original mounting position and engagement geometry in the BV50A drive assembly.
The friction spring in a backpack concrete vibrator sits within the drive mechanism that transfers rotational power from the motor to the flexible shaft and vibrator head. It works by applying controlled frictional resistance that allows the drive to slip slightly under shock loads, protecting the shaft and motor from sudden overloads. When this spring wears out or loses tension, the drive connection becomes unreliable — you may notice reduced vibration intensity, intermittent output, or complete loss of drive to the head. Replacing the friction spring with a genuine part like the Wacker Neuson 5000217222 restores the correct slip threshold and keeps the vibrator delivering consistent consolidation force in the concrete.
