Ac question

[STERLING STINGER]

Hey guys.... I have recentley been hearing a squeak in what seems to be my ac unit.

I spray some pb blaster in it and it stops for a min or so. I just put some oil in it now...just a little from the outside...and it lasts a little longer. (no squeak)

I really love and need my ac, so I don't want to remove it and put a bracket in there.

 

Is there an easier way?

Like do they sell just the part the belt rides on?

Or is there any other suggestions?

I really appreciate the help

 

Thanks again guys!

I assume youre talking about the belt at the compressor. Where are you applying oil to? If youre applying oil to the clutch discs, youre probably screwed at this point. The compressor clutch needs to stay clean and dry from oily residues. Some places do just sell a clutch kit for the compressor, but it will usually cost as much as a complete compressor will or real close to it. You may try just tightening your drive belt as well. I had a similar issue and tightening the belt took care of the noise. Ive also seen them make noise because the belt was old and glazed... just needs a new belt at that point. Good luck.

How tight should the belt be?

I believe there is a special tool to measure to tightness(?) with. My Haynes manual says what it's supposed to be set at. But I usually go to "right about there"...

[STERLING STINGER]

Haha. Ok I'm gonna try to tighten it up a little

[STERLING STINGER]

ok i just tried to tighten the belt

i think when i took my belt off i turned the bottom adjustment screw in to much

i try to adjust it now and its just not working

:fs1:

[Boots]

I don't think that you can put it in to far...You have to thread it all the way OUT to take it apart. Why did you take the belt off , you can tighten it with the belt on.

ok i got the tightening of the belt down....now, what about this ac pulley?

i see a bearing that they sell

is that what i need?

[STERLING STINGER]

ok i just spoke with my pick n pull guy and hes pulling the whole ac assembley out for me for $18.00

my next question is

 

do i have to replace entire unit or just the clutch pulley?

it seems like i can just bolt the new clutch pulley on to my existing unit.....i said unit..lol

 

and

 

do i have to drain the freon out to do this job?

 

please help!!!

down to 1 truck and i am losing $$$ everyday i can't drive!!!!!!!

 

thank you

[STERLING STINGER]

i just took off the ac clutch plate and there was a bunch of gunk in there so i cleaned both sides up a little with some scotchbrite and noticed that my bearings grinding...lol

here's the other side.....not cleaned yet....from what ive read, the washers/shims are very important

 

 

i called the used part store and am getting a whole ac unit $60

then ill have a spare ac

[STERLING STINGER]

Well the bearing in the pulled part was bad also. Went to another place that had one pulled for me and that bearing was bad too.....

So after a thousand rejected calls for the bearing, or clutch, I stumbled across dj Nickolus.

The only thing is it's only 65$ when it's $200+ everywhere else.

He said he didn't have a pic but it said clutch pulley

It's coming in by 9 am tomorrow so we shall see if it's the right part

 

I also got the clutch pulley off and apart, including bearing.

 

Is anyone even reading this?

[STERLING STINGER]

here's some more pics

I have replaced a lot of bearings in those AC clutches. Its kindof tricky to get the bearing out and in without bending the pulley. Also look at the snout on the front of the compressor where the bearing slides on, and make sure it isn't worn .Looks like you already have the bearing out of the pulley , so if the pulley is not bent, youre half way there!

[STERLING STINGER]

Ya now I just need a bearing and I should be ok!!

[alleydog]

You bet! I get mine at the local Napa store

[STERLING STINGER]

Ya my napa here is run by a coulpe of a-holes

They all look down on u if u don't have a lifted, diesel dodge

Lol

Plus they didnt have it when i called anyways

[carnuck]

What's the number on the bearing? They may have it listed wrong or not have the alternate correctly listed.

[STERLING STINGER]

Na its ok

I'm on my way to the pick n pull now

Thanks anyways for the help

[STERLING STINGER]

Well swapped out bearing....still squeaking noise

Alt maybe?

Fan clutch?..

No clue

 

At a loss

[bighause]

I fought a squeak for a long time. Mine turned out to be two things: harmonic balancer rubbing timing cover and the double bearing on the shaft for the mechanical fan

[STERLING STINGER]

Wow that sounds s@itty

I was gonna try a new belt tomorrow

If that don't work, i have no clue what to do

 

Thanks for the info!!

[alleydog]

I just replaced the damper on my 89 last sunday, with a used one. It was rubbing on the timing cover. It made kind of a swishing sound. maybe its just your belt. They will quit squeaking with just a little spray of almost anything, like brake cleaner or carb spray. Then as it dries off they start squeaking again.I have heard the best belt to use is a Goodyear gatorback.

[STERLING STINGER]

Damper??

[STERLING STINGER]

Ok i took off the belt and started my truck to see if it was the big pulley on the bottom squeaking

Its not

My alt is not spinning freeley either. Ctheres some resistance there so I'm replacing that next

[STERLING STINGER]

Got it.

It was the belt and a bunk idler pulley from advanced auto

I wasted 2 days on this. On and off. For a bunk part!!!!!

Aaaaaaaaahhh!!!!!
