Key Features
- Genuine OEM Integrity — Manufactured to the original design tolerances for the UM-SERIES, ensuring the shaft transmits vibration energy efficiently and consistently through the head assembly.
- Direct-Fit Replacement — Engineered to install into UM-SERIES handheld vibrators using the existing attachment points, with no modification to the housing or head required.
- UM-SERIES Compatibility — Verified fitment for Multiquip UM-SERIES handheld concrete vibrators, including the UM128 specification referenced in the part description.
- Sustained Vibration Output — A sound lead shaft assembly maintains consistent amplitude and frequency delivery to the vibrator head, which is critical for proper concrete consolidation and eliminating voids.
- Wear-Resistance for Demanding Use — Concrete vibrator lead shafts are subject to continuous flex and rotational stress; this OEM assembly is built to handle that cyclic load over extended service intervals.
The lead shaft assembly is the flexible drive component that connects the motor unit of a handheld concrete vibrator to the vibrating head. It transmits rotational force down the length of the shaft, converting it into the high-frequency vibration that consolidates freshly placed concrete and drives out entrapped air. When a lead shaft wears, kinks, or fails, vibration output drops off or stops entirely, leaving concrete under-consolidated and compromising structural integrity. Replacing a worn lead shaft assembly restores full vibration performance and extends the working life of the vibrator head.
