The Wacker Neuson Spider Assembly Hub Left is a genuine OEM component designed for the CRT36ASO and CRT36ASN 915mm/36-inch ride-on concrete trowels. Sourced directly from Wacker Neuson, this part carries the same specifications as the original assembly installed at the factory. It fits both the overlapping and non-overlapping rotor configurations within the CRT36 series, making it straightforward to confirm compatibility against your machine's model number before ordering. When your existing hub assembly shows wear or damage, replacing it with the correct OEM part keeps your trowel operating at its intended performance level.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original dimensional and material specifications, ensuring the spider arms and hub interface maintain correct rotor geometry during troweling passes.
- Left-Side Specific: — Designated for the left rotor position; confirm left vs. right orientation before ordering to ensure a direct installation without rework.
- CRT36 Series Compatibility: — Verified fit for the CRT36ASO (overlapping) and CRT36ASN (non-overlapping) 915mm/36-inch ride-on trowels.
- Rotor Drive Integrity: — A correctly functioning spider hub transfers drive torque evenly across the trowel blades; a worn or cracked assembly causes uneven blade pitch, surface defects in the finish slab, and accelerated bearing wear.
- Part Number Confidence: — Ordering by Wacker Neuson part number 5000087926 ensures you receive the exact assembly for your CRT36 configuration, not a generic substitute.
The spider assembly hub is the central rotor hub component that connects the gearbox output to the trowel blade arms on a ride-on power trowel. It distributes rotational force from the drive system evenly to each blade, while allowing the pitch of the blades to be adjusted for different finishing stages. On the left rotor of the CRT36, this assembly is subject to continuous mechanical stress and loading; if it cracks, deforms, or develops excessive play, blade pitch control becomes inconsistent, resulting in rippling or tearing of the concrete surface and potential damage to surrounding drivetrain components. Replacing a worn spider assembly hub promptly restores even torque distribution and keeps the finishing rotor running true.
