The Wacker Neuson 5100005711 Flex Shafts SM 5S is a genuine OEM flexible shaft assembly designed for the M1500 and M2500 series internal concrete vibrator drive units. As a direct OEM replacement, the 5100005711 is manufactured to Wacker Neuson's original specifications, ensuring proper power transfer from the drive motor to the vibrator head without adjustment or adaptation. Confirmed fitment spans multiple M1500 and M2500 configurations, including 120V US, 230V EU, and 120V GB variants, as well as the M2500/230 EU W drive engine application.
Key Features
- Genuine OEM Torque Transmission: — Built to the original torsional and dimensional spec for the SM 5S shaft profile, ensuring full power delivery from drive unit to vibrator head without slippage or loss.
- Direct-Fit Shaft Assembly: — Engineered to connect directly to compatible M1500 and M2500 drive motors using the original coupling interface — no reworking of the drive end or head connection required.
- Broad M-Series Fitment: — Compatible with M1500/120 US, M1500/120 GB, M1500/230 EU, M2500/120 US, M2500/120 GB, M2500/230 EU, and M2500/230 EU W drive engine configurations.
- Consistent Vibration Output: — A correctly functioning flex shaft maintains the rotational energy needed for effective concrete consolidation; a worn or kinked shaft causes erratic or reduced vibration at the head, leading to inadequate compaction.
- OEM Part Number Confidence: — Part number 5100005711 is the authoritative Wacker Neuson reference for this shaft assembly, eliminating guesswork when ordering for service or field replacement.
The flex shaft in an internal concrete vibrator is the mechanical link between the electric or motor-driven power unit and the vibrating head inserted into fresh concrete. It transmits rotational force along a flexible, armored cable body, allowing the rigid drive unit to remain stationary while the head is maneuvered through the pour. Over time, flex shafts wear from repeated bending, high-speed rotation, and exposure to concrete slurry; a degraded shaft exhibits vibration loss, heat buildup at the casing, or complete failure to spin the head — all of which compromise concrete consolidation quality and slow the pour.
