Ariens traction belt idler out of place. Just a bad belt?

[I have some difficulties getting this post to go through, so apologies if this shows up in duplicate]

I have a 9 year old 920013 which has worked well with occasional routine maintenance. This year, it worked fine for the first snowfall. The next time out the drive seemed off, occasionally slipping. I found that not squeezing the drive handle all the way made it work better, and I was able to complete clearing the driveway.

I suspected the friction disc needed to be replaced, but it actually looks fine. What I see is that in a resting position, the traction belt idler, while tensioning the belt, is being pulled all the way down and is resting on the frame which supports the motor. Lifting it up, I see it has worn a crescent-shape into the frame. If I pull on the opposite side of the belt, the idler moves up off of the frame into a more vertical position where you would normally expect it to be. It is as if the belt is a couple inches too long.

I have not yet replaced the belt, since it is not available locally and replacing it requires a fair amount of disassembly. I am sure that over 9 years the belt has stretched and worn, but is it reasonable that it could have done so to this extent? I'm hoping the group here can comment on the likelihood of this.

I will attempt to post images in a reply below.

Thanks!

In resting position, the traction idler is pulled down and is resting on the motor frame


When I pull on the opposite side of the belt, the idler lifts up off of the frame and is correctly positioned


Note the crescent-shaped wear just visible past the auger belt idler, under the traction idler


In resting position, the traction idler is pulled down and is resting on the motor frame


A better view: When I pull on the opposite side of the belt, the idler lifts up off of the frame and is correctly positioned

Yup belts worn. I have to do the same on my 921018.

9 years just regular maintenance we did good waiting this long to change the belts.

It's good to have confirmation that this is a belt issue, but it's a bit disappointing that an old intact belt can cause the idler to grind the frame of the machine. This does not seem like a great design.

Since the belts are not available locally, where online do you folks order your belts? OEM straight from Ariens? I notice they don't give the exact size for the belts (7200101 and 7200513/7200725), making it harder to go with a 3rd party.

Also, any tricks to changing out the belts? I saw a video on Youtube that it's possible on some Ariens to avoid decoupling the machine, at least for the auger belt replacement.

I buy kevlar belts if available, on ebay, amazon, OPE suppliers, etc.

I found some links that show belt sizes.

I prefer to buy OEM belts or aftermarket from Stens.

I get most of my parts online from Jacks Small Engines. They match up the exact belts to your unit. But there are others.

If you go to Ariens website, they are good about having all the historical manuals available to guide you through the belt change. It wonít be too bad. But youíll be taking the auger housing off first.

Thanks for the replies and information. I've gone ahead and ordered a new belt. Hoping to install it later this week.
