The Multiquip 11981 Right Side Spider Assembly is a genuine OEM component designed for STH series hydrostatic ride-on trowels. As an authentic Multiquip part, it is manufactured to the same specifications as the original, ensuring a direct, consistent fit within the trowel's blade pitch control system. This assembly is sold and fulfilled by DHS Equipment, an authorized Multiquip parts distributor. Verify your model against the STH series before ordering to confirm compatibility.
Key Features
- OEM-Grade Structural Integrity — Cast and machined to original tolerances, so blade pitch response stays accurate and consistent under continuous load.
- Direct-Fit Replacement — Engineered to mount in the same position and connect to the same linkage points as the original assembly, with no adaptation needed.
- STH Series Compatibility — Matched to STH hydrostatic ride-on trowels; use your model code to confirm application before installation.
- Right Side Specific — Designated for the right-side blade assembly; using the correct side-specific unit preserves symmetrical pitch control across both rotor heads.
- Sustained Finishing Performance — A worn or damaged spider assembly causes uneven blade pitch, resulting in inconsistent surface finish and increased operator fatigue; replacing it promptly restores full troweling control.
The spider assembly is the central hub component that connects the pitch control linkage to the trowel blades on a ride-on power trowel. It translates input from the hydraulic pitch control system into uniform blade angle adjustment, allowing the operator to dial in the correct pressure and finishing action across the concrete surface. When the spider assembly is cracked, worn, or seized, blade pitch becomes erratic or unresponsive, leading to poor surface quality and potential damage to the trowel's drive components.
