Smog pump hole help

I'm removing my smog stuff...can i just plug the smog pump oulet remove the hoses plug vacuum lines so i can keep the same belt until i get the delete kit ensuring the belt fits right? In other words can the smog pump still be driven by the belt but not doing anything or will it screw something up?
 
if you leave it with a belt on it ,it will be real noisy running pumping air without a hose .so what I do is gut it . very easy to do. take the back plate off and get a hammer and a chisel and knock everything in it out , but be careful not to damage the bearings. and if you dont get every little piece out it will lock up going down the road. i've dun this on over 10 mustangs and never had a problem.
 
You can simply remove the smog pump and measure for a shorter belt and eliminate it with out buying the eliminator if you know what i mean.
