i bought my jeep about 2 years ago and i had a squeaking belt that always loosened up on me every 6 months or so... so ive decided to buy a new one, heh, i'm on my 3rd belt now in 1 month, i went through two duralast and now the dayco i bought 2 weeks ago got chewed up as well. well it doesnt get chewed up so bad as to a snapping point, but it does chew up the last inner ridge... engine side if you know what I mean. can it be one of the pulleys? itll run good for a week or two, but then the same thing happenes ridge gets chewed up... and im on my 3rd belt. i dont have an ac compressor and i do buy the correct belts. maybe i put em on to tight... i usually leave about 3/4" slack. can anyone help me out?
1) I'm not sure what its supposed to be, but I think that might be too loose.
2) check all your pulleys or anywhere else the belt touches for any kind of sharp edge.
3) look at your engine from the side, and visually check to make sure all the pulleys are inline with each other. I was working on an old VW and one of the pulleys was about 1/4-1/2 an inch farther out than the other one. The belt lasted about 40 minutes before it shreded...
What have we got?
We have one heavily armed Recreational Vehicle
Never experienced that..... but I would suspect a pulley misalignment issue. Can you get a straight edge in there to see if you have a wobble or a bent edge???

Had 75CJ5, 89YJ, 93YJ. Have 82CJ7 & 95YJ____Not one burnt yet due to lack of relays.
Both mine and my brothers do shred the one tooth belt or whatever it is I looked at mine noticed my power steering is a little out of alignment. But I just let it go I have a spare just in case tho haha
I do not know about the Duralast but the Dayco belts are literally too wide. I went through virtually the same thing... went through three before going to Napa... no more shredding! I still have to adjust the belt every couple of weeks though
i have to adjust mine also because it loosens up after a few weeks. and whats sucks on mine is it is a huge pain in the ass to get on since my block is a 99, my alt is an 87, and my waterpump is an 89. mine never chews up the blets but they just don;t stay tight and since i have the old style adjust the alternator to tighten the belt set up, i put a pry bar between the alt and the ac mount and yank it tight and it still comes loose.
as long as i don;t have the ac on when i start the jeep though, it doesn;t squeek
A lot of teenagers are people who express a burning desire to be different be dressing exactly alike.
Panties aren't my favorite, but they're right next to it...
No one is normal, there are just a lot of weird people with things in common.
If the belt is loosening it has to be one of 2 problems. Either the belt is stretching or the tightener is loosening. If the belt is stretching it is too tight. BUT then it should stretch to be right and never stretch to be too lose. Physics thing.
So, the thought is that the tightener is not staying put. If it is the alternator, then check and see if you can double bolt the slide mechanism. If there is an area of the slot open on the tightening side you can put a bolt/nut on that and use it to block the alternator from sliding/slipping loser.
You don't want to tighten the belt too tight or you will take out the bearings, usually the bushing in the water pump.
Also, check and be sure you don't have the wrong width belt. Probably a 1/2" but worth checking.
Mine done the same thing.one of my idler pulleys would lock up when it got hot and would burn it into.it took me forever to find it.after the 3rd belt come off I checked every pull for sharp edges with no luck.I spun one of my idler pulleys and it made a sound.when I took it off a couple of bearings where missing and after it got hot it would seize up and slowly eat the belt off.

I had the same problem after I replaced my steering pump. My steering pump pulley was 1/4" out further than the rest. I took it to my mechanic to see if he had some special tool to move it and he did. Free of charge.
After inspecting it turned off for worn [shiny] spots on belts, look for things that could be touching the belt; I had a friend who went through two before he realized the sharp end of a lower hose clamp was up against it. With a flashlight - and minding all the moving bits - watch it while it's running, looking for any imbalance or stuck pulleys. And double-check the deflection: 3/4 inch seems like to much to me, too, but I'm not looking at it, either.
