Multiquip 11940 Spider Retainer

The Multiquip 11940 Spider Retainer is a genuine OEM component designed for STH series hydrostatic ride-on trowels. Sourced directly from Multiquip, this part matches the original specification for a straight-swap installation with no guesswork. Keeping the spider assembly properly retained is critical to consistent blade pitch control and smooth trowel operation. If you're servicing an STH hydrostatic ride-on trowel, the part is the correct OEM retainer for the job.

Key Features

• Genuine OEM Retention Integrity — Manufactured to Multiquip's original design spec, ensuring the spider assembly stays properly seated under the dynamic loads of continuous troweling cycles.
• Direct-Swap Installation — Matches the original mounting configuration of STH series trowels, allowing straightforward installation during routine blade pitch servicing.
• STH Series Compatibility — Confirmed fitment for STH hydrostatic ride-on trowel models, so you can order with confidence when referencing your machine's model code.
• Supports Accurate Blade Pitch Control — A correctly functioning spider retainer holds the spider mechanism in proper alignment, enabling consistent pitch adjustment across all blades for a level, high-quality finish.
• OEM Quality for a Precision Drive Component — The spider retainer operates within the hydraulic pitch control system where dimensional accuracy matters; genuine OEM construction maintains the tight tolerances this mechanism demands.

The spider retainer secures the spider assembly — the central hub mechanism that transfers blade pitch adjustments to each individual finishing blade on a ride-on trowel. When the operator adjusts pitch through the hydrostatic control system, the spider assembly translates that input into consistent blade angle changes across the rotor. A worn or failed retainer allows the spider to shift out of position, leading to uneven blade pitch, inconsistent surface finish quality, and potential damage to surrounding pitch control components. Replacing it promptly with the correct OEM part keeps the pitch system operating as designed.
