The Multiquip 22328-01 Hayes Coupling is a genuine OEM component designed for STXD6i and HTXD6i hydrostatic ride-on power trowels. As a direct factory replacement, this coupling meets the original engineering specifications for these machines, ensuring correct engagement and power transmission within the drivetrain. Sourced directly from Multiquip, part number 22328-01 is the exact coupling specified for these units — no guesswork on compatibility.
Key Features
- Genuine OEM Construction — Manufactured to the original material and dimensional specifications that Hayes couplings in this drivetrain application demand, maintaining proper torque transfer characteristics.
- Direct Bolt-In Replacement — Engineered to install in the same position and mounting configuration as the original, so the swap is straightforward without fabrication or adaptation.
- Confirmed Fitment — Compatible with Multiquip STXD6i and HTXD6i hydrostatic ride-on trowels; verify your model before ordering.
- Drivetrain Integrity — A worn or failed coupling causes vibration, slippage, or complete loss of power transmission — replacing it promptly restores smooth, consistent blade and drive operation.
- Backed by Multiquip — Carrying the genuine Multiquip part number 22328-01, this component is fully traceable and supported through the authorized Multiquip parts network.
A Hayes coupling is a flexible jaw-type coupling that connects two rotating shafts within the trowel's drivetrain, absorbing shock loads and slight misalignments while transmitting rotational power. In a hydrostatic ride-on trowel, this coupling plays a critical role in transferring drive force cleanly between the hydraulic motor and the output shaft. When the coupling element wears or cracks, operators will notice increased vibration, inconsistent blade speed, or a complete loss of drive — all of which directly affect finish quality and machine control on the slab.
