Multiquip 32642 CVT Upper Clutch Gray Flyweight Assembly - OEM Replacement Part

The CVT upper clutch assembly with gray flyweight controls the variable speed transmission system on ride-on power trowels, enabling smooth blade speed transitions during concrete finishing operations. This critical component regulates rotor speed as operators adjust blade pitch from initial floating to final burnishing stages.

The continuously variable transmission (CVT) clutch uses centrifugal flyweights to automatically modulate power delivery to the dual counter-rotating rotor assemblies. As engine RPM increases, the flyweights engage progressively to transfer power through the gearbox to the blade spider assemblies. Proper CVT operation is essential for maintaining consistent blade rotation during the finishing process, especially when transitioning between combination blades for initial floating and finish blades for burnishing.

Signs that this upper clutch assembly may need replacement include inconsistent rotor speed, excessive vibration during operation, unusual noise from the transmission housing, or difficulty maintaining blade speed under load. Regular inspection of CVT components helps prevent unexpected downtime during critical concrete finishing operations.
