Multiquip 42528 Trunnion Square Double DOF Assembly - OEM Replacement Part

The trunnion square double DOF (degree of freedom) assembly is a critical articulation component in ride-on trowel hydraulic systems, enabling precise blade pitch control and edge height adjustment during concrete finishing operations. This dual-axis trunnion mechanism allows independent movement in two planes, essential for maintaining optimal blade angle and ground contact pressure as specified in Multiquip's setup and calibration procedures for hydraulic ride-on trowels.

Engineered for professional concrete finishing equipment, this assembly maintains the mechanical linkage between the hydraulic steering system and trowel rotor heads. Proper function of the trunnion assembly is critical during machine setup procedures, including stroke sensor calibration and pitch pressure adjustments detailed in the STX6H service manual. Worn or damaged trunnion assemblies can result in inconsistent edge height, improper blade pitch control, and compromised finish quality on concrete surfaces.

Compatible with the following Multiquip model:

• STX6H Hydraulic Ride-On Trowel
