The Multiquip 21492 Pulley is a genuine OEM component designed for CA-4-4H, CA4HM, and CA4.4HM series walk-behind power trowels. As a factory-sourced part, it meets the exact specifications required by Multiquip for these machines, ensuring the drive system operates as intended. DHS Equipment supplies this pulley direct, so you can confirm fitment by part number and order with confidence. Compatible models include the CA-4-4H, CA4HM, and CA4.4HM power trowels — verify your model code before ordering to ensure a correct match.
Key Features
- Genuine OEM Dimensional Accuracy — Sourced directly from Multiquip, this pulley is manufactured to the exact bore diameter, groove profile, and belt engagement specs required by the original drive system.
- Direct-Fit Installation — Engineered to mount and align to the original shaft and belt path on compatible trowel models, eliminating the need for fitment adjustment during installation.
- Confirmed Fitment — Compatible with CA-4-4H, CA4HM, and CA4.4HM walk-behind power trowels in the Multiquip and Whiteman portfolio.
- Drive System Integrity — A correctly sized pulley maintains proper belt tension and rotational transfer to the trowel blades, keeping finishing performance smooth and consistent across the full blade sweep.
- Long-Term Wear Resistance — OEM construction ensures the pulley holds belt contact geometry over extended use, reducing belt slip and uneven wear that can affect blade speed and surface finish quality.
The pulley is a core component of the drive system on a walk-behind power trowel, transferring rotational force from the engine to the trowel blade assembly via belt. When the pulley is correctly sized and properly seated, it maintains consistent blade speed and smooth power delivery across the finishing pass. A worn or damaged pulley can cause belt slippage, erratic blade rotation, or accelerated belt wear — all of which compromise the quality of the concrete finish and increase wear on surrounding drive components.
