The Wacker Neuson Spider Hub Right is a genuine OEM component designed for the CRT36ASO and CRT36ASN 915mm/36in Ride-On Trowel series. As a direct factory replacement, this part meets the original design specifications Wacker Neuson built into these machines. It is the right-side hub assembly within the spider rotor system, making correct side identification essential before ordering. Always cross-reference your machine's serial number against the CRT36ASO or CRT36ASN model to confirm fitment before purchase.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original design tolerances, ensuring the hub seats and interfaces correctly with the rotor spider assembly without dimensional compromise.
- Right-Side Specific — This is the right-hand spider hub; confirm your machine's rotor orientation before ordering to ensure you receive the correct-side component.
- Direct Replacement for CRT36 Series — Fits the CRT36ASO (overlapping) and CRT36ASN 915mm/36in Ride-On Concrete Trowels, covering both overlapping and standard rotor configurations.
- Rotor System Integrity — A worn or damaged spider hub causes uneven blade pitch, erratic rotor motion, and compromised surface finish quality — replacing it restores smooth, consistent troweling action.
- Operational Safety Relevance — A failed hub in a ride-on trowel rotor assembly can lead to unexpected rotor imbalance during operation; using a genuine OEM replacement maintains the structural integrity of the rotating assembly.
The spider hub is the central mechanical interface between the trowel's rotor drive shaft and the blade arm assembly. It transmits rotational force outward to the finishing blades while supporting the pitch-adjustment mechanism that controls surface pressure and finish quality. When the spider hub wears, cracks, or fails, blade pitch becomes inconsistent, rotor balance is lost, and the machine can no longer produce a uniform concrete finish — making timely replacement critical to both output quality and operator safety.
