The Multiquip 21675 Pulley AK-32 X 3/4 is a genuine OEM component designed for the CA4HM walk-behind power trowel. Sourced directly from Multiquip, this pulley is manufactured to the exact dimensions and tolerances required for proper belt engagement and drive system performance on the CA4HM. Keeping the drive system running with correctly spec'd components helps protect the machine from premature wear and uneven load transfer. DHS Equipment stocks this part ready to ship so you can get your trowel back in service fast.
Key Features
- Exact OEM Dimensions — Manufactured to the precise AK-32 x 3/4-inch bore specification, ensuring correct belt seating and proper alignment with the drive system.
- Genuine Multiquip Part — Direct from the OEM, this pulley meets the same material and machining standards as the original component it replaces.
- Direct Replacement for CA4HM — Confirmed fitment for the Whiteman CA4HM walk-behind power trowel; installs in place of the original without modification.
- Drive System Integrity — A worn or undersized pulley causes belt slippage, uneven blade speed, and accelerated belt wear; this OEM replacement restores proper drive engagement.
- Long-Term Drivetrain Protection — Correct pulley geometry distributes belt tension evenly, extending the service life of belts and bearings throughout the drive assembly.
The pulley on a walk-behind power trowel transfers rotational power from the engine to the trowel blade gearbox via a drive belt. When the pulley is worn, cracked, or out of spec, belt tension becomes inconsistent, leading to slippage, vibration, and reduced blade speed control. Replacing a damaged pulley promptly keeps the drive system operating efficiently and prevents secondary wear on belts and adjacent drivetrain components.
