I have a 2006 Yamaha Grizzly 660 and i purchased a big wheel clutch kit.

The issue I am having is I can't remove the bolt centered on either the first or secondary clutch. I have heard that you can us a impact wrench to remove these but how do u get them back on?

Does anybody know if you need a special tool to remove and replace these bolts?
If you need a tool where can i buy or rent one?

please help

 

You can remove and install them with an impact wrench and deep well sockets. You do not need a special tool. Just make sure someone who is experienced uses the impact on reassembly so you dont overtighten and strip the bolts.
