I have looked and searched but have not found any great descriptions on how to devane the smog pump. If anyone could share with me I would appreciate it. The pulley on mine sheared off the other day and I had to remove it and order one from cruiserparts.net, I am wanting to devane it as the truck had been semi de-smogged prior to me purchasing it. Had I been stronger in the funds department I would have just gone with a specter idler pulley, but oh well. If anyone could shed some light on this I would appreciate it......
