Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original dimensional and material standards, ensuring the EM214 Pulley delivers consistent belt engagement and load transfer specific to this application.
• Broad Cross-Equipment Compatibility — Fits ride-on power trowels (HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, STX55Y6, STX55J6, HHN31V, HHN34TVD, MD80, MD105, LD6 and more), walk-behind trowels (CA4HM, J36E2, J3036H55), and diaphragm pumps (MQD2H, MQD2HA, MQD3H, MQD3HA).
• Correct Belt Alignment — OEM groove profile and bore dimensions ensure the drive belt seats and tracks properly, eliminating premature belt wear caused by mismatched aftermarket pulleys.
• Sustained Drive System Performance — A worn or damaged pulley causes belt slippage, vibration, and loss of blade or pump drive power. Replacing with a properly dimensioned OEM Pulley restores full torque transfer and smooth operation.
• Verified Part Number — Order with confidence knowing EM214 is the exact Multiquip part number for this Pulley, cross-referenced across ride-on trowel, walk-behind trowel, and diaphragm pump applications.

A pulley is a rotating disc or wheel with a grooved rim that guides and transfers power from a drive belt to a driven component such as a blade gearbox or pump impeller. In power trowels and diaphragm pumps, the pulley forms a critical link in the drive train — transmitting engine output to the working assembly. When a pulley becomes worn, cracked, or out of round, the drive belt loses proper tension and tracking, leading to slippage, excessive belt wear, reduced output power, and potential drive system damage. Replacing a failed pulley promptly with the correct OEM component restores proper belt geometry and protects surrounding drive components from secondary wear.
