Multiquip 40140 CVT Lower Driven HHN Service - OEM Replacement Part

This CVT lower driven assembly is a critical drivetrain component for Multiquip walk-behind power trowels, transmitting power from the engine to the trowel blades through a continuously variable transmission system. The lower driven unit converts rotational force and enables smooth, variable speed control essential for achieving proper concrete finishing results across different surface conditions and curing stages.

As a service assembly, this part is engineered to restore full drivetrain functionality when the lower driven unit experiences wear, vibration, or power transmission issues. Signs that replacement may be needed include inconsistent blade speed, unusual noise from the transmission area, difficulty adjusting RPM, or reduced torque transfer to the finishing blades. Regular inspection of CVT components helps prevent unexpected downtime during critical finishing operations.

This CVT lower driven assembly is compatible with the following Multiquip model:
