Hi. It's been a while.

My health has gotten the best of me. I have gotten to the point where I can do very little with my truck, when it comes to fixing things. Still need the truck running though, because it is how I get water from town.

Just as a reminder, My truck: late 92 F250 lariat. 7.3 4Wd

My problem: It keeps throwing the belt. Occasionally also chews the belt up if it gets caught.

The pulleys are aligned. And I can feel no resistance or grittiness in any of the pulleys. Everything seems to be fine.

It does fine at idle. It's when I try to accelerate that it throws the belt. And I am talking normal acceleration. Not revving it a lot, or fast acceleration.

The only thing I can figure is that maybe there is something in the bearings of one of the pulleys that only gets in the way, when it is sped up. But I can't think of any way to individually test the pulleys at speed, without removing some or all of them.

There's only one of me, so I can't stand out there in front of the truck at the same time I am pressing the go pedal.

Right now, I am down to just trying to find a better serpentine belt. Yes, I know everyone is going to say that I need to do what it takes to find the real problem and fix it. I can no longer do that. I just need my truck running, and don't have the health to do all the work I used to do on it. And I REALLY cannot afford to take it to a shop to get it fixed.

I have been using the 'masterpro' from Oreilleys. K061110 (6K1110)

It specifies "Without the Leece Neville alternator."

It's the shorter of the two belts available there, for my truck.

I have read about there being better belts. Belts designed to stay on, in tougher conditions. Such as the 'gatorback' by goodyear. I have not been able to find a gatorback that will fit my truck.

There are gates belts available at my local oreiley's as well. Green belts. One is 49 dollars, the other is 150 dollars. I really can't see any difference between them. They are items I have to order. The 150 dollar one being a special order, so I can't send it back. I'm not wasting 150 bucks just to put hands on, to see if it is actually any better or not.

So the question is, does anyone know of a better belt? One that will stay on, in rougher conditions?

I need your own experience, not what some advertising blurb says. I can read advertisements, my own self. LOL

Thanks guys!!! :thanks:

I wish I could help, Selahdoor! I was thinking about you a couple days ago and the big fire you had a couple years back.

Im skeptical that a different belt could help but maybe someone knows something i don't.

Open spring tensioner?
That's what they do.

I swapped to the one with the shock.

So, o realy belts...
I just did one after realizing that the other one was several years old...

Wait for it.....
after less than 1k easy miles back n forth to the coast, it started screaming, so I flipped it around and drove home from the coast...
You're going to need the serpentine tensioner bracket to swap out the open spring one.
Good luck.

Also wondering if I already have the open spring design on the tensioner, can I even replace that with the closed spring design, or the shock kind???

Will either of those even bolt up where an open spring design does?

I've grenaded the shock tensioner and the closed style (one of each). When I grenaded the closed one, it was actually under warranty as I bought it from the dealer (many moons ago, I'm guessing 2008ish) so they gave me a new one. What they didn't give me was a new idler, which got damaged when the belt shrapnel'd, fortunately I noticed it was buggered up and swapped it out with the belt and warrantied tensioner. The alignment of all the parts is pretty critical to belt life, but i'd bet your tensioner is the culprit as it's really the only thing that "moves". Swap it when you swap the belt. If it doesn't fix anything put it behind the seat for a spare as all the IDI tensioners are suspect IMNSHO.

I have had really good luck with the Gates green belts.

In any case: you take care of yourself over there in Index :)

Not going to be able to change the open spring tensioner with an enclosed one without swapping the base mount out also!

Thank you.

Yes, I was already planning on replacing both the tensioner and the idler. Even though I replaced the tensioner about 3 years ago. It's the cheapest open spring one from oreileys, and I have always suspected it, every time the belt has come off since then.

I'll look for both with metal pulleys. And I suspected as well that I wouldn't be able to use the enclosed spring kind. Without changing that bracket as well. Since I have no idea where to get the bracket, and no strength left right now, to go looking for one. I'll just try to find the best tensioner that I can.

I wish I could hear from someone that knows the difference between the green gates belts at oreileys. One is 49, the other is 150. Their pictures don't tell me anything at all. And I just figured out the pictures they use are 'representative' anyway. So, completely useless.

Call gates, I bet one is gates industrial quality, and the cheaper one is parts store spec.
(Read same size, cheaper components)
