I have an 06 G85, and I have ordered my Stage 2 kit through the parts dept at work. Im a technician at the dealership and I will be doing the instal my self. There is no posted Pulley tool, so I was wondering what "pulley tool" I should use. The J number would be appreciated, how ever any information on pulling the pulley off is appreciated. Thanks!

 

use a 20 ton press to take the stock pulley off....
then the tool to put it back on is a std(per gm) alternator pulley install tool

 

Ok, we have the press, how ever how did you secure the supercharger on the press, and I'd assume nose down? Thanks for the info.

 

no use 2 plates to go under the pulley with the TB side down, someone hold the body of the s/c from underneath use a nut or something to sit on the nose of the s/c shaft and press down on that with your aluminum or whatever spacer and press it down while the pulley is held still by the plates, after you give it some pressure you will hear a huge POP and then you can just finish pressing the shaft down
Person below catches the s/c

 

also if you dont want to mar the pulley put some flat cardboard in between the pulley and the plates

 

great thanks for the info, Ill post what happens once I get the kit.

 

I purchased and used this puller/installer http://www.zzperformance.com/cobalt_...00e5bc9a0bf719 and it worked great!
