The Wacker Neuson 5100005713 Flex Shafts SM 9S is a genuine OEM flexible shaft assembly designed for M1500 and M2500 series internal concrete vibrator drive units. As a direct OEM replacement, part 5100005713 is manufactured to the same tolerances and materials as the original component that left the factory, ensuring consistent torque transfer between the drive motor and the vibrating head. Compatible fitment spans multiple voltage and regional configurations, including M1500/120, M1500/230, M2500/120, and M2500/230 drive units.
Key Features
- OEM Torque-Transfer Specification — Engineered to the same torsional stiffness and flex radius as the original shaft, maintaining consistent power delivery to the vibrator head under continuous concrete consolidation loads.
- Drop-In Shaft Replacement — Matches the SM 9S coupling profile and shaft diameter of the original, connecting directly to compatible M1500 and M2500 drive motors without modification to the housing or head connection.
- Broad M-Series Fitment — Confirmed for M1500/120 GB, M1500/120 US, M1500/230 EU, M2500/120 GB, M2500/120 US, M2500/230 EU, and M2500/230 EU W drive engine configurations.
- Sustained Vibration Output — A worn or damaged flex shaft causes irregular vibration amplitude, leaving air pockets in the pour; a correctly functioning shaft keeps the vibrator head running at full, consistent frequency for thorough concrete consolidation.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, carrying the OEM part number 5100005713 for straightforward verification against your machine's parts manual.
The flex shaft is the mechanical link between the drive motor and the internal vibrator head, transmitting rotational force through a flexible, armored cable that allows the head to be positioned at angles the motor alone cannot reach. In concrete consolidation work, the shaft must transfer torque smoothly and continuously; if the shaft develops kinks, fraying, or wear at the coupling ends, vibration output at the head becomes erratic or drops out entirely, compromising the quality of the concrete pour. Replacing a degraded flex shaft restores full rotational speed to the vibrator head and ensures the drive unit operates as intended.
