Dr. Pulley 17g slider install, 2007 Aprilia Scarabeo 500ie. I'm ready to get started and yes my garage is carpeted! Remove the four outer cover bolts. I removed the forward most allen head bolt from the air box, this allows enough movement of the air box for the outer cover to come off. Next I removed the seven permitter bolts and the four longer middle cover bolts. Next was the clutch bolt, I had my helper sit on the scooter (off the center stand) and hold the rear brake. Using a two foot breaker bar the nut came loose with little effort. Then the cover comes right off. I then bolted on my variator holding tool, and using the same two foot breaker bar I backed the variator nut off with little to no effort. http://www.scooterwest.com/items/?_...etails/Piaggio-500-Variator-Holding-Tool/2445 Half way off. Make sure you reach behind the variator and hold it together when sliding it off. This way rollers wont go everywhere. Same goes for re installing I just pinched it together with my fingers on the right side about the 4 O'clock postion and held it till it was seated all the way back. Looks good. Stock rollers, 2000 miles on them. Dr. Pulley 17g A quick wipe down and inspection and I dropped in the Dr. Pulley 17g sliders in. It took less then 30 minutes to remove and replace, just work backwards to re assemble. Make sure when you put the variator back using the holding tool the belt is free, it can bind up on the ramps. Just pinch the belt and make sure it has movement back and forth as you began to tighten the variator nut down. Use a good torque wrench and set the bolt. Put the belt cover back on, use and alternating pattern when tighten the bolts back down. Put the scoot back on two wheels have your helper hold the rear brake and using a good torque wrench set the clutch bolt. You should not need or ever use a electric or air powered torque gun on these components...IMO Put the plastic outer cover on, tighten the four bolts and don't forget the air box bolt and the clutch nut cover/plug. Your all done, easy job anyone with basic tools and a little knowledge anyone can do this.
