Key Features
- Genuine OEM Construction — Machined to original Multiquip specifications, ensuring the correct groove profile, bore diameter, and belt alignment for the HDA-SERIES drive system.
- Exact-Dimension Replacement — 5.25-inch outer diameter and 7/8-inch bore match the original pulley geometry, allowing direct installation without machining or shimming.
- HDA-SERIES Compatibility — Verified fitment for Multiquip HDA-SERIES heavy-duty walk-behind power trowels, covering the full range of models in that family.
- Consistent Belt Drive Performance — A correctly sized pulley maintains proper belt tension and speed ratio, allowing the trowel blades to run at the intended RPM for a consistent finish.
- Sourced from an Authorized Distributor — Purchased through DHS Equipment, this is a genuine Multiquip part backed by OEM traceability — not a generic substitute.
A drive pulley transfers rotational power from the engine to the belt that drives the trowel blade assembly. By maintaining the correct diameter and bore fit, the pulley sets the blade speed and keeps belt tension within the design range. When a pulley wears, cracks, or loses its groove profile, the drive belt slips or tracks unevenly, causing inconsistent blade speed, accelerated belt wear, and an uneven concrete finish. Replacing a worn pulley with the correct OEM part restores the intended power transfer and protects the belt and other drive components from premature wear.
