The Wacker Neuson Spring Washer is a genuine OEM component designed for the CT24-4A walk-behind concrete power trowel series. Sourced directly from Wacker Neuson, this spring washer matches the original part specification for a direct, hassle-free installation. Compatibility is confirmed for the CT24-4A and CT24-4A EU trowel models, including the 610mm/24-inch walk-behind configuration.
Key Features
- Genuine OEM Spring Tension Rating — manufactured to the exact load and deflection characteristics required for correct clamping force in the CT24-4A trowel assembly.
- Drop-In Replacement — matches the original fastener stack-up geometry, seating correctly without any rework to surrounding hardware.
- Confirmed CT24-4A Fitment — verified for both the CT24-4A and CT24-4A EU (610mm/24-inch) walk-behind concrete power trowel variants.
- Maintains Consistent Clamping Load — a worn or fatigued spring washer loses its ability to maintain preload, which can lead to fastener loosening under the vibration loads generated during troweling. Replacing it restores proper tension.
- Genuine Wacker Neuson Part — backed by Wacker Neuson's OEM quality standards, ensuring the part performs as the machine was engineered to operate.
A spring washer is a hardened, curved or wave-form washer positioned beneath a fastener to apply and maintain a consistent clamping load against vibration and thermal cycling. In a walk-behind concrete trowel like the CT24-4A, where rotating blades generate continuous vibration, spring washers play a critical role in keeping fastened connections secure throughout the finishing pass. When a spring washer loses its temper or becomes flattened with age, it can no longer maintain preload, allowing bolts to work loose and creating both performance and safety concerns. Replacing a failed spring washer with the correct OEM part restores the integrity of the fastened joint.
