Dr. Pulley Variator Slide Set (Aprilia, Piaggio, Vespa 50)

Dr. Pulley Variator Slide Set (Aprilia, Piaggio, Vespa 50)

Description: Dr. Pulley Variator Slide Set for Aprilia, Piaggio 50, Vespa 2-stroke engines. The Slide Pieces in the variator are equally as important as the rollers. It is highly recommended to change the slide pieces to coincide with the rollers. The Dr. Pulley Variator Slides are made of the same abrasion-resistant nylon as the Dr. Pulley Roller Weights, which promises a long life.

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.
