Squeaky belts

I traded that truck off and bought an 07 with a NXS in it.

 

Nope, no play whatsoever.

That would be about like replacing your jakes every time you have an overhead done, not gonna happen.

 

Well, a little update. I tried the soap thing, made it pretty quite, but didn't stop it entirely. I did find some belt dressing at a TA, sprayed that on and it stopped for about one minute, then came back even louder, sprayed the piss out of both sides of the belt and that worked for about five minutes, that changed the pitch of it considerably. Stopped in Spokane at Cat and bought both idler pulleys and a new tensioner, $511 later. They are the big 12 grove ones.

Went over to the J and installed them, fired the truck up and everything was nice and quite, as I am putting my stuff away I hear a very faint squeak, it progressively gets louder until it sounds like cats fighting under the hood, spray it down good with the belt dressing, stops for about five minutes and comes back. I'm to pissed off at this moment to mess with it anymore, down the road I go.

Get over to Missoula and its still noisy, but is bearable. I have another new belt with me so I throw that on thinking that maybe the other belt with everything that it has been thru is just going to be noisy now, new belt is quiet for a few minutes, but back to the same old same once again. Talked with my local Cat shop and he said he thinks its a bearing in the fan hub that has the belt out of alignment just enough to make it squeal. Going to see if Cat in Missoula can get at it in the morning, I don't need the dam thing coming off and going thru a new radiator.

 

Mine has serpentine belts.

 

It ended up being the alternator. Took the truck into Inland Truck Parts and Service this morning, they checked everything out, spun the alternator backwards and it would squeak a little. They put a new on and all is nice and quiet.
