Genuine Piaggio centrifugal clutch with three clutch shoes for the current 310cc Vespa and Piaggio models. The complete clutch assembly is part of the automatic CVT transmission and is mounted on the driven pulley. Depending on engine speed, it automatically engages with the clutch bell to transmit power.
As engine speed increases, centrifugal force moves the three clutch shoes outwards. The friction linings come into contact with the inside of the clutch bell, transferring engine torque to the final drive. When engine speed drops again, the clutch springs pull the shoes back to their initial position and disengage the drive.
The product images show the complete pre-assembled centrifugal clutch with three clutch shoes evenly positioned around its circumference. Each shoe features a large friction lining on its outer surface. The shoes are pivot-mounted on the clutch carrier and are returned to their initial position by the visible clutch springs.
The rear shows the metal construction of the clutch carrier with several reinforcing sections and the pivot points of the three clutch shoes. The central mount features a flattened profile for positive positioning within the clutch assembly. The design corresponds to the standard clutch specified by Piaggio for the 310cc drivetrain.
The clutch is a functionally and safety-relevant component of the CVT transmission. During installation, the condition of the clutch bell and driven pulley as well as the correct fastening of the clutch must be checked in accordance with the manufacturer's specifications.
The friction surfaces of the clutch linings and clutch bell must remain free from grease and oil. Work on the CVT transmission should be carried out using suitable tools and in accordance with the specified tightening torques.
