The Multiquip 42528 Trunnion Square Double DOF W/A is a genuine OEM component designed for the STX6H super-sized hydrostatic ride-on power trowel. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. Confirm part number 42528 against your machine's parts manual before ordering to ensure correct fitment for your STX6H unit.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the trunnion assembly interfaces correctly with the blade pitch control linkage on the STX6H.
- Double DOF Design — The dual degree-of-freedom configuration allows multi-axis movement within the trowel's pitch adjustment mechanism, maintaining smooth and accurate blade angle control.
- Direct OEM Replacement — Part number 42528 installs as a direct swap for the original trunnion assembly, requiring no reworking of existing mounting points or linkage hardware.
- STX6H Fitment — Engineered specifically for the STX6H super-sized hydrostatic ride-on trowel, part of Multiquip's heavy-duty STX series.
- Restores Blade Pitch Response — A worn or damaged trunnion assembly causes imprecise blade angle control, leading to uneven finishing passes; replacing it restores full operator control over pitch adjustment.
The trunnion assembly is a pivoting structural component within the blade pitch control system of a hydrostatic ride-on trowel. It connects the hydraulic or mechanical actuator to the spider arm assembly, translating operator input into precise blade angle changes across the finishing pan. When the trunnion wears or fails, operators will notice inconsistent blade response, vibration in the handle controls, or an inability to achieve uniform pitch across all blades — all of which directly affect the quality of the finished concrete surface.
