Multiquip 20470 Output Shaft

The Multiquip 20470 is a genuine OEM Output Shaft designed for a wide range of Multiquip and Whiteman walk-behind and ride-on power trowels, including BS46H11, BS46H90, JS36H55, JS36H90, J36-M30, B46, B46S90, BH11C, BH90C, BS90C, JH55C, JH90C, and JS60C models. As a direct OEM replacement, this shaft is manufactured to the same standards as the original component it replaces, ensuring a correct drop-in fit with no guesswork on compatibility. DHS Equipment stocks Multiquip OEM parts to keep your finishing equipment running at full capacity. Verify your model against the fitment list above before ordering to confirm this is the right part for your machine.

Key Features

• OEM-Grade Shaft Integrity — Manufactured to the original dimensional and material tolerances that Multiquip specifies for power trowel drivetrain components, ensuring correct torque transfer from gearbox to blade spider assembly.
• Direct Drivetrain Replacement — Engineered to install in the same position as the original output shaft, connecting to existing gearbox and blade spider hardware without modification to surrounding components.
• Broad Trowel Fitment — Compatible with BS46, JS36, B46, BH, BS90C, JH, and J36-M30 series Multiquip and Whiteman walk-behind and ride-on power trowels, covering both 36-inch and 46-inch blade diameter configurations.
• Smooth, Consistent Blade Rotation — A correctly functioning output shaft maintains steady blade speed and uniform finishing action across the full sweep of the trowel head; a worn or damaged shaft introduces vibration, blade wobble, and uneven surface finishing.
• Genuine OEM Part Number — Part number 20470 is sourced directly from Multiquip, so you receive the same component supplied through authorized dealer channels — no substitution, no re-engineering.

The output shaft is a core drivetrain component in a walk-behind or ride-on power trowel. It transmits rotational power from the gearbox to the blade spider assembly, which in turn drives the finishing blades across the concrete surface. When the output shaft is worn, bent, or damaged, operators will notice increased vibration at the trowel head, uneven blade contact with the slab, or complete loss of blade rotation — any of which compromises the quality of the finished surface and can accelerate wear on surrounding drivetrain parts. Replacing a failed output shaft promptly with a correctly specified OEM part restores proper power transfer and protects the gearbox and blade components from secondary damage.
