Will a V8 a/c delete pulley work on a 3.1?

 

u do not need an ac delte pully.do u have a air pump on urs? if u run a shorter pelt u can go right from the ps to the alt/tensioner
----------
if u dont have the airt pump i can even give u the part number for the belt to run it this way

if u have an air pump u run it the same way eaxcept it goes from alt to pump to crank, u would have to measure with string though to get the right measure ment and allow 3/8's of an inch for belt stretch

 

yes I have an air pump. my a/c compressor went & I dont have the $ to fix it. I bought a non a/c belt and the belt rubs on itself from the power steering to the water pump before it gets back to the tensioner. thought a delete pulley would be a quick fix but cant find one for a V6. did a search-is there possibly 2 mounting positions for the power steering bracket depending on if you have a/c or not?

 

get a shorter belt . it hits cause the tensioner is not pulled back enough,the furthe rback the tensenor the higher the belt will be

 

I can't remember who, but someone is quite certain that there are two PS bracket positions, with one having the bracket slightly higher than most.

I've done a ton of searching into this and have only found a handful of people that can just use a new routing without rub. If it's the tensioner's fault, then it's still a bad idea, because as soon as the tensioner begins to wear, your belt pops off. I'd rather have the bracket.

Now for smog pump, simply using a new belt does seem to work there.

 

be aware that these cars had 2 diff size altanater pullys so if u some how have the small one it will make the belt short. i found this one out the hard way after yanking an alt from the jy and putting it on and wondering why my belt no longer tightened up

 

That would be me. I have done the belt length thing with both upper holes in the PS bracket, and, IIRC (measured last summer but haven't had the money to do anything yet), there is like a 1.5-2" difference just by tilting the PS pump up farther. When I get back home Memorial Day, the first thing I am going to do is go to my fav J/Y and see if that 91 is still reasonably in one piece so I can take pics and snag a few parts. It's got a 3.1 without A/C.

 

u knwo the more i think about this i do belive that u can use one of either 2 hole son the top of the bracket.i have mine int he top left hole wich forces the pulley out twards the outside of the car which would lower the pully.but would also make the belt u need longer.i cant tell u if a non ac belt would fit like that though cause i also removed the smog pump.i belive street lethal used the same routing i did and even had a measurement for the correct lenght belt

 

Here's another view for you. I have an 82.5" belt and it doesn't rub at the area in question...

 

I tried using the non-AC, non-AIR belt, and it was a bit too short for me, as I couldn't get the belt around the tensioner. I didn't even think about the other hole at the time, and returned the belt because it didn't fit. The thing is, I REALLY want to junk the compressor, as that and the evaporator are the only AC parts I have left in the engine compartment, and I would kind of like to save the weight. The rest went not too long after the 2.8 went out.

:edit: My 3.1 USED to have the AIR pump, before it was put in my car. One of the first things I did was remove the leftover bracket from the engine. Now, if I could just snag a P/S exhaust manifold, I could get rid of that annoying check valve, the #5 exhaust leak, and have an easier time changing my plugs...

 

I just deleted the A/C compressor on my 3.1 a few weeks ago. I have to keep the air pump for now, and all I had to do was pick up a belt for a non-ac 92 camaro rs and change the belt routing.

I attached a quick Paint diagram but basically it goes from the alternator down to the air pump, then over the water pump, around the crank, power steering, then back to the alternator. I've got about 1" clearance going over the water pump, but it's tight enough that it doesn't rub. If you've taken the air pump off, you can try a belt for a non-a/c 89 2.8. It's a couple inches shorter and may fit just right for you.

 

Here's one from when I had my 3.1 project going....;

 

I must have the smaller alt pulley-is there a part # for the larger one? My ps pump bracket is attached with the left hole. If I move the bracket to the right hole will the ps pump lift enough to not rub? The belt I bought is Napa part #6K905 for a non a/c Camaro with air pump. It is 91 inches long. Thanks everyone for your input.

 

I decided to give on more shot at it, using the 82.5" belt mentioned in here, along with a brand new tensioner...and it works! It's a very tight fit. Aka, you can barely fit your pinky between the belt where it goes over the water pump. Here's pictures. My car came with smog and AC, all of which have been deleted. Now I can finally junk the compressor too(and I just paid $7 for new bracket bolts! Drats!).

For anyone who is doing this, make sure your tensioner is not worn out like mine is. In a setup like this, if your tensioner ever wears out, the belt will probably fall right off, prompting another $48 tensioner. And a $43 belt, if it's destroyed when it pops off.

 

u cannot change the ps mounting hole to the right hole without modifying the bracket that is on the back of the pump.fork i think u could have gone with an 82 inch belt what u have to remeber is u need to account for 1/4- 3.8s inch of belt stretch and belive me after 2-3 days the belt will stretch a bit. i will take my belt off and re measure it. i will also measure the diamiter of the 2 diff altamator pullys i have this way we can come up with solid belt numbers for everyone that wants to do this.


btw forkvoid u can remove the ac compressor bracket u dont need it on there to hold the ps pump

umm did u change ur water pump to a standard rotation water pump?? cause if not ur spinning it backwards which means ur water pump is doing nothing for u

 

I haven't changed the water pump, no. The pump is turning the same way that it was when the original belt was on the car. I checked it about a dozen times. I suppose it's possible I had the standard rotation water pump to begin with?

If you look at my diagram and yours, the water pump is turning the same direction. It also looks like I accidentally ran the belt OVER the tensioner, instead of UNDER it in my diagram.

 

i think only the vbelt cars got a standard rotation wp, looking at ur diagram again ur a deff turning it the wrong way? or maybe im just still half alseep and missing something.lol somone else take a look at his diagram and tell me if ive lost my mind or not

 

It's actually on there because I needed the compressor for the belt. I just haven't taken it off yet.

 

82" is just barely too short, you won't be able to get it on. I think you will have that rubbing with an 83". Depending on the parts store, you may be able to get a belt between 82" and 82.5" to get a slight bit more clearance, but you'll also have a lot more preload on the tensioner.

It's spinning the same direction (thats the routing the factory used) only difference is the belt is being pulled up to the water pump on the left side of the crank vs the right side.

 

i cant remeber what lenght my belt is if i have time later ill go pull it off and measure it its a pin on my car cause the turbo is actually in the way of getting a wrench on the tensioner to lossen it up to get the belt on or off.ive gota lay on the ground and change the belt from the bottom,one of these days ill make a tool that will let me change it from the top side

fit the changing the water pump wasnt for you that was directed at 92rs_ttop and the way he drew his belt routing diagram i belive hes spinning his wp backwards

 

Project89 - I could very well be wrong on the wp rotation, I didn't really look at the way it actually spun once I changed it. Correct me if I'm wrong here, but the crankshaft pulley will turn clockwise with the engine running? If I'm right on that, then it will essentially push the belt up onto the water pump pulley which would force it to turn in a counterclockwise direction. From what I have read in other posts, the water pump on a serpentine belt system should turn counterclockwise, and it should turn clockwise on a v-belt system? Right?

 

now that ive had my morning soda and am awake i just looked at the diagram again u have the belt on the right way being as u had the belt on the oposite everyone else does threw me off

 

Yeah, was gonna route it the other direction initially, but for some reason the belt ended up about 1.5-2" too long. It was a belt for a 92 RS without a/c so I figured it would follow basically the same routing as it did with the a/c. I haven't run the car much since it's not quite ready to go back on the road yet, but the 20 minutes or so that I ran it for the other day, I didn't notice any rubbing or any problems with overheating.

I completely understand about the waking up thing, I start work at 7am and am not usually truly "awake" until about 11am. I'm just hoping your not in the same time zone as me, it's 3:30pm here

 

yeah i am but i was up till like 530 am im usually up around 6 thopugh

 

That's certainly understandable then. I sometimes forget that people with normal jobs are off on sundays.

 

Oh I know, I was just telling you it's spinning the correct way. You did ask for someone else to look at it.

 

Yes...it will work. I went to Advance Auto last year and got one for a 305 because the A/C had the same mounting holes as a V6. Here is a pic I posted last year. You can get an original delete pulley off Ebay or something. Probably better made.
