Multiquip 12086 Trunnion Complete

The Multiquip 12086 Trunnion Complete is a genuine OEM component designed for STH series hydrostatic ride-on trowels. As a direct OEM replacement sourced through Multiquip's authorized parts network, this assembly ensures the mechanical integrity your finishing equipment depends on. Confirm your model code against the STH series before ordering to ensure correct fitment.

Key Features

• OEM-Grade Pivot Integrity — Manufactured to Multiquip's original design tolerances, ensuring the trunnion assembly maintains consistent blade pitch response under continuous hydraulic load.
• Drop-In Assembly Replacement — Supplied as a complete welded assembly, matching the original mounting geometry of STH series hydrostatic ride-on trowels for a straightforward swap-out.
• STH Series Compatibility — Engineered specifically for STH hydrostatic ride-on trowel models; verify your machine's model code before ordering.
• Blade Pitch Control Performance — A correctly functioning trunnion assembly is critical to smooth, precise blade angle adjustment — a worn or damaged trunnion leads to erratic pitch response and uneven concrete finishing.
• Structural Weld Assembly — Delivered as a fully welded complete unit, eliminating the need to source and assemble individual pivot components in the field.

The trunnion is a pivoting mechanical assembly that connects the blade spider to the pitch control linkage on a hydrostatic ride-on trowel. It allows the operator to adjust the angle of the finishing blades during operation, which controls the amount of pressure and float applied to the concrete surface. When a trunnion wears out or becomes damaged, blade pitch becomes inconsistent or unresponsive, resulting in poor surface finish quality and potential damage to freshly placed concrete.
