The Multiquip 43194 Square Double DOF Trunnion is a genuine OEM component designed for STXDF, MD80, and MD105 series ride-on power trowels. Sourced directly from Multiquip, this trunnion meets the original engineering specifications for these hydrostatic and dual-fuel trowel models. It is a direct-fit replacement that installs to the same mounting points as the original, keeping your machine operating to spec without adaptation. Confirm your model code before ordering to ensure an exact match for your machine.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original tolerances for the pivot geometry and load-bearing demands specific to ride-on trowel blade pitch systems.
- Direct-Fit Replacement — Matches the original square double-degree-of-freedom mounting configuration, dropping into place on STXDF, MD80, and MD105 trowels without rework.
- Broad Ride-On Trowel Compatibility — Fits the STXDF super-sized dual-fuel series and MD80 and MD105 mid-sized hydrostatic ride-on trowel models.
- Blade Pitch Control Integrity — A correctly functioning trunnion maintains smooth, consistent blade pitch adjustment; a worn or damaged trunnion causes erratic blade response and uneven surface finishing.
- Verified OEM Part Number — Part number 43194 is the factory-designated reference for this trunnion, removing the guesswork when sourcing a replacement.
The trunnion is a pivoting support component within the blade pitch assembly of a ride-on power trowel. It allows the pitch arms to rotate and articulate along two degrees of freedom, translating operator input into precise blade angle changes across the trowel head. When a trunnion wears, cracks, or seizes, blade pitch becomes inconsistent or unresponsive, directly compromising the flatness and finish quality of the concrete surface being worked.
