i need to remove mine and want to replace it with the idler pulley!

anyone done this? what's the part number for the idler pulley and how hard is it to do this?

 

I removed the air on my 83, was a much different process than a 91 though... I've never seen a part number for the AIR pump delete pulley, but they do exist.

The problems you'll likely run into are finding the plugs for the holes in the manifolds. 1/4" NPT pipe plugs will thread in far enough to stop leaks, but they aren't correct. Classic Industries sells plugs for this purpose for $1/ea.

Then there are the air tubes that go behind the back of the block... you'll need to unbolt them and probably cut them to get em out.

Personally on a serpentine system I'd just leave them be... if the setup still works, there's no reason to mess with it. Its not like its a serious parasitic drain.

 

leave it on and disconnect the two plugs in the actuator box on the pass. side. it will prevent the clutch from locking up in the ir pump thus just letting it spin freely also you can leave the air tubes on there as long as the one way check valves are on it wont leak.(kind of messy but does the same conclusion you want)

 

i found plugs at a local hardware store for 49 cents each...the manifolds will hopefully be gone soon and a set of hooker headers will be in its place

 

-Smog Delete Pulley: P/N: 10186167

 

Or you could just check the tech articles on this web site, there is a nice detailed description on how to reroute the serpentine belt after removing the smog pump.

 

Yes it is much easier to just by a shorter belt and reroute it, then to get a delete pulley. That is exactly what I did.

thanks for the insight drew, i have headers though so pluging any holes isn't a problem.

as far as the hoses, there aren't any connected anywhere on the car anymore, i removed all the parts, all i have left is the hunk of metal connected to the pulley and a metal tube that routes from this straight up into the air.

i removed the black box that sat on top as well as disconnected the wires. it flows freely, this isn't the problem, it's the constant clicking of the check valve trying to close because air is trying to get in. causing my car to sound like it has a rod knock. hense the need for an idler pulley so it will spin freely. when i had my headers installed they removed all the hoses so i don't know about any that go to the back of the block, but they're not there now.

i know the pulley exists, it's also cheaper than purchasing an rerouting a new belt. hense the reason i want it.

thanks for all the help so far, if anyone else has anything else to comment please let me know. i've tried to plug the pipe, but when accelerating the pressure is to great and my car sounds like a wreck all because of the air fluttering....i need a solution fast.

 

solution is just a belt. you need nothing else. how is an idler assembly cheaper than a belt. you remove the AIR pump and reroute with a new belt.

and here is the article and pictures.

 

well, when i went to buy a belt it's price was roughly $28.......the idler pulley i was told is under that, as well as i don't have to change my stock belt!

looks like a savings to me.....

 

by how much? $10? and let's see. when the idler pulley goes bad, you'll need to replace it. so long as you still find it. nothing bad here. just that it seems your going through alot of energy to find an idler pulley that was only put on cars overseas. just so you don't put a belt on.

 

i see.........

as much trouble as most seem to think i'm going through to find this "pulley", most are going through the same effort to stop me or tell me that i'm crazy. $10 is $10 dollars, most of you can appreciate cost cutting right!

i completely appreciate the comments as well as suggestions, alternatives and the like, if i had to resort to changing to a different belt then i would definately do so. but, since it isn't that much trouble to ask a few questions as well as be able to keep the stock belt and routing and everything else that can be effected by this i would prefer to go this route.

i don't want to come off sounding like a jerk, just like i'm sure those of you who won't accept my idea do either........it can be done, has been done, and i want to do it.

if your happy with a different belt and such that i'm glad, as well as i think you for the suggestions, it's just not the way i want to go.

again, thanks everyone who sent me the info i needed, my pulley should be her mid week! :lala:

 

yes. $10 is $10. i see you found one. i was going to suggest making one. all you would need is some flat plate steel or aluminum and a generic idler pulley.

 

I just removed my a.i.r. pump this weekend and also replaced the
A/C compressor with a A/C delete pulley.
I also reused the stock belt (for a 89 Corvette L98 which is what my motor is )

i am trying to clean up all the useless clutter under the hood,and since there is no emissions inspection or testing around here it's just taking up space.

 

if you removed the a.i.r. pump, what did you do with it; did you just route your belt different? or did you do something to the pump that let it rotate freely?

 

I took all of my AIR off and had no problems. The 1/4 fittings that someone stated about not working, work perfectly. Everything is off my car that had something to do with the AIR.

 

I removed my pump and bought the belt listed in the tech. article. It works perfectly, and the bay is cleaner.

 

what about the power steering pump? am i missing it in the tech article, or do you just not run with it? i thought the article said runs with all accesories.

 

Hey Kandied91z
I feel your pain, I took mine out with no prob, the only prob I had was, locating the pulley though, I got a hook up at the local chevy dealer and he said he couldn't locate the pulley I had to order it from on line. Its like a chevy dealer online, anyway I don't have the number on me, but go to the tech article and they should have it on there, now there's a wrong number floating around there, The way to find out what is the right one, it's going to be a pulley for a Caprice, thats the one you want. It cost about 45 dollar with shipping but I like the look better then just nothing there. And it s a lot easier to locate a belt, in case of a emergency. I got a pic of it too I ll send it to your email, I don;'t have a post on line anymore.

 

thanks for the pic, i forgot to update; i ordered my pulley last thursday it arrived one week later.....

but, it was the right part and works and looks perfect, plust the best part is i don't have to change my belt! total cost for my part was a little more than i was told which came out to 32 something. but, it does exactly what i wanted it to plus it saved me 10 pounds over the existing part! for those who care about that stuff.

almost forgot, the p/n on the tag reads 1018-6167 and says pulley as. i tried looking it up at gmpartsdirect to check it and nothing came up? so who knows, but for those who said it doesn't exist and tried to stop me.........ha! i've got one and it works great!
:lala:

 

87 setups are so much easier to work with
Remove AIR system... project done!
No pulleys to get, no belts to run other than stock.
Removing the system really cleans up the engine bay.

 

The 1/4 plugs are the correct size and work fine.

Ditto the 87 it was easy...
