cs144 squealing

[BGW]

I had two of them, but my mom threw them out

Fixed it for you

Tons of great suggestions running the same type alternator

Good belts are the key the pulley is fine. Ivory soap NO NO NO NO NO. matched as well as possible I'm using Gates belts & mine don't do it. I did have some no names on it & they did when I first put the 144 on. Those belts do look a litttle tired.

Just for fun years ago I was having this exact problem & could not make it stop until I foungd out it was my powerstering actually squealing.

HA was trying to be funny. YEAH it sucks.

OK Im going to go ahead and replace all 3 with gates brand. Gotta order some other things from rockauto anyways. I figured ivory soap was a bad idea, but I was frustrated and just needed to move the jeep 2 miles before I went back to college. Where did that idea even come from, seems like ALOT of people do it.

I know its not the power steering. Laying under the jeep the sound is definitely coming from the alt. Plus that pulley gets hot as heck even after a minute or two. I was really thinking the alt was fried until I took the belts off and it spun smooth with zero play.

The belt contact patch is not the best on the V8's with AIR to start with,
add low battery (sitting for a while), old belts, lack of adjustment with the
SI-12 lower bracket pretty much gets to slipping belts.
As Ristow stated a little bump in pulley size is not a bad idea, matched set belts (kind of hit and miss at the auto stores), lower bracket built for the
cs144, some or all of the above should get you to where they don't slip.
(Tight is pretty tight like ~90ish lbs tension per belt)

If I can find another pulley that works ill do that, but i have no idea where to find one that will work. But I do need to get another one of your brackets if you still have any!

What do you mean by belt contact patch? I did remove my AIR system completely.

Not to speak for MDill as I'm sure he can do that but I think he is talking about how the belts don't wrap very far around the alternator pully if you have AC.

With AC you have to wrap from the Crank, Alt, AC, Water Pump. This means the actual ammount of Alt pully that is in contact with the belt is pretty small due to it having to go up the block and drive the AC instead of wrapping around the pully and going straight back to the WP. Even when the AC isn't being driven just the fact that it is there means there is less contact patch for the belt to drive the Alt.

If you removed the AC as you say then you have a better situation for your belts to live in. Personally since I still have my AC and have to tension my Alt from the bottom and can't get a good angle on it, I have to tighten it as much as I can, then make it a little tighter, then pull a muscle getting it a little tighter before I snug it down.

What he said, The belt contact area on the alt pulley, is marginal with AC, which makes having good belts with proper tension a must with the big alt.

OHHH ok. Yes your right the belts is really not in contact with that pulley very long.

Those look great, is that the biggest you would go?

-Both of those are for diesel engines and have an inner diameter of .669". Would that even fit?

Notice

At the bottom there is a phone number call him he will hook you up the first one is exactly what I have they have hundreds of applications.

Notice Title says GM applications all diesel in GM land have 144's.

OK thanks for the info I didnt know that.

I've never had any luck mixing and matching old belts in dual setups. Never works for me. I go to the parts store and have them pull every Gates of whatever application I need and go through them all to find the two that match closest and run them. Works fine so far but I haven't installed my 144 yet. Reckon I might step up to a larger pulley while I'm at it.

BTW usually the belt length is in the part number for Gates belts. You can usually ask for a 52blahblah or 53blahblah to get longer ones.
