Multiquip 21081-001 Driven Pulley

The Multiquip 21081-001 is a genuine OEM Driven Pulley designed for STX55J6 and STX55Y6 Whiteman ride-on power trowels. As a direct OEM replacement, this part is manufactured to the same specifications as the original component, ensuring a proper fit within the drive system of your STX55 series trowel. Sourced directly through authorized Multiquip distribution, part number 21081-001 gives you confidence that you are installing the correct component the first time.

Key Features

• Genuine OEM Construction — Manufactured to original drive system specifications, maintaining the correct belt engagement geometry and load-bearing capacity required in a ride-on trowel application.
• Drop-In Replacement — Mounts directly in place of the original driven pulley with no alterations to surrounding drive components needed.
• STX55 Series Fitment — Confirmed for STX55J6 and STX55Y6 Whiteman hydrostatic ride-on power trowels.
• Drive System Integrity — A worn or damaged driven pulley causes belt slippage, uneven blade speed, and loss of power transfer — replacing it restores consistent trowel blade performance and drive efficiency.
• Verified Part Number — Ordering by Multiquip part number 21081-001 eliminates guesswork and reduces the risk of installing an incompatible component.

The driven pulley is a core component in the belt-drive system of a ride-on power trowel, receiving rotational force from the drive belt and transferring it to downstream drivetrain components that control blade speed and machine movement. When the driven pulley is worn, cracked, or out of true, belt tension becomes inconsistent, leading to slippage, vibration, and reduced finishing performance. Replacing a failed driven pulley with a genuine OEM component restores proper power transfer and keeps the trowel operating at the blade speed and consistency the operator depends on.
