The Multiquip 43106 Trunnion Single DOF Assembly is a genuine OEM component designed for the MD80, STXDF, and MD105 hydrostatic ride-on power trowels. As an authorized Multiquip OEM part, the 43106 delivers the exact fit and material specification the machine was engineered around, ensuring consistent blade pitch control performance. This assembly is confirmed to fit the MD80 and MD105 mid-sized hydrostatic series as well as the STXDF dual-fuel super-sized hydrostatic trowel. If you are maintaining or rebuilding a ride-on trowel in one of these families, the Multiquip 43106 is the correct OEM-specified replacement.
Key Features
- OEM-Specified Pivot Geometry — Manufactured to Multiquip's exact dimensional tolerances, maintaining the single degree-of-freedom pivot motion the blade pitch system depends on.
- Direct-Swap Installation — Mounts to the existing blade pitch linkage using the original hardware configuration, requiring no modification to surrounding components.
- Confirmed Fitment — Verified for the MD80, MD105, and STXDF hydrostatic ride-on power trowels.
- Blade Pitch Precision — A worn or damaged trunnion causes erratic or uneven blade angle response; replacing it with a correct OEM assembly restores consistent pitch control across all blades.
- Genuine Multiquip OEM Part — Sourced directly through the Multiquip authorized supply chain, ensuring the 43106 meets the same material and hardness standards as the original production component.
The trunnion assembly serves as the pivot interface within the blade pitch control linkage of a hydrostatic ride-on power trowel. It allows the pitch arm to rotate through a controlled single axis of movement, translating hydraulic or mechanical input into precise blade angle changes across the trowel's spider assembly. When a trunnion wears, develops play, or fails, blade pitch becomes inconsistent or unresponsive, resulting in uneven finishing passes and potential surface defects in the concrete slab. Replacing the trunnion assembly with the correct OEM part restores the tight, controlled pivot action the machine requires for accurate surface finishing.
