I did a search and didnt come up with anything. I am going to be removing my V.1 Alta 15% pulley and was wondering if I will need a puller or do they come off when you unbolt them. Im assuming they come off without a puller, but just wanted a second opinion before I dig in.

 

It comes off without the puller. Just loosen those socket cap crews and it should come right off. Then slide the collar off the supercharger. Some wd-40 might help if things are tight but try it without first.

 

Remove the fastening/clamping bolts first, there are two threaded holes on the pulley face, using bolts longer than those used for clamping (same thread pitch and diameter), screw in to separate. No need to go as far as the photo below, it is only a general illustration; I’m using Campy quick release skewers here.
