The Wacker Neuson Spider Retaining Washer is a genuine OEM component designed for the CT24-4A and CT24-230E series walk-behind concrete power trowels. Sourced directly from Wacker Neuson, this washer delivers the exact fit and material specification required for proper spider assembly retention. Confirmed fitment covers CT24-4A, CT24-230E, and their EU-market variants, making this the correct replacement for 610mm/24-inch walk-behind trowel applications.
Key Features
- Genuine OEM Material Spec — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring the washer seats and retains the spider assembly correctly under continuous troweling loads.
- Direct Spider Assembly Fit — Replaces the original retaining washer position-for-position, requiring no rework to the spider hub or fastener pattern.
- Broad CT24 Series Coverage — Compatible with CT24-4A, CT24-230E, and EU-configuration variants of both models, covering gas and electric 24-inch walk-behind trowel platforms.
- Maintains Spider Assembly Integrity — A worn or missing retaining washer allows axial movement in the spider assembly, leading to uneven blade pitch, surface chatter, and accelerated wear on surrounding components.
- Verified OEM Part Number — Part number 5000174955 is the factory-authorized reference for this washer across all listed CT24 configurations, eliminating guesswork when cross-referencing your machine's serial documentation.
The spider retaining washer secures the spider assembly to the gearbox output on a walk-behind concrete trowel, locking the rotor in its correct axial position as the blades rotate across the concrete surface. Without proper retention, the spider can shift under load, causing inconsistent blade contact, vibration, and uneven finishing results. Replacing a worn or damaged retaining washer restores the precise blade geometry the trowel depends on to produce a flat, smooth finish.
