Description: Dr. Pulley 20x17mm Sliding Weights for the Aprilia, Piaggio, Vespa 125/150cc, and many more. Traditionally, the gear ratio is changed by the up-and-down rolling movement of the rolling weights in the ramp of the Moveable Drive Pulley (MDF). Now the innovative Dr. Pulley Sliding Weights slide up-and-down the ramp to change the gear ratio. This unique sliding movement (not rolling) provides exclusive advantages to increase CVT performance. With Dr. Pulley, no abnormal wear will occur even when running in high gear. Dr. Pulley's U.S. Patent Number 7,276,004 states that their sliding weights eliminate abnormal wear, prevent reduction gear ratio deterioration, prolong the useful life of the transmission, and have the availability to adjust reduction gear ratios as well as driving performance. At the same time, Dr. Pulley Sliding Weights are also adapted to compensate for wear automatically, to adjust by itself to move further outward in a movable drive pulley half, and to make the vehicle reach a higher maximum vehicle speed.

Installation: 1. Slack the belt by opening the CVT clutch gives belt slack to the variator side. 2. Then install the variator drive face while lifting the slack belt further away from the center boss if done properly should not see any splines between variator drive face slop-side and boss flat-side. Should be flushed together. 3. Then install the existing variator fan, washer, and hand-tight nut. 4. Finally, apply blue Loctitetorque nut to 30-35ft-lbs. For reassurance please consult your manufacturer's variator torque specs.
