Ariens 13HP Impeller and auger blades won't engage

I posted a year ago about my impeller and auger blades not engaging and was able to get that fixed. But now I have a new problem with the same machine.

I have an Ariens 924505 STE with a 13HP Tecumseh Snow King engine. The impeller and auger blades aren't turning at all. I know the reason but I don't know the fix and am hoping you guys can help me out.

While the sheave is turning very well, and while I engage the auger lever/handle and the idler lever and idler wheel move, they apparently are not moving enough to remove the slack in the V-belt to create the tension in the belt that would then spin the Ply-V wheel. Therefore the impeller/augers aren't spinning.

Here's an overview of what I've checked:
- The roll pins on the impeller are in-place (2 of them) and not sheared off, broken nor missing
- The shear pins in each one of the auger segments are in place and good to go
- The auger blades do not spin when turned by hand (further demonstrates the shear pins are good). I can get them to turn a very little bit by hand if I put a lot of force to them but they do not spin freely like a roulette wheel.
- the impeller turns a little bit when, as I state above, I'm able to slightly turn the auger blades a slight bit with a lot of force by hand.
-- when I take the belt cover kit off, I can see the smaller belt and associated pulley spinning rapidly (sheave wheel) but when I engage the auger control lever the V- belt and associated bigger Ply-V wheel/pulley don't move at all because there is too much slack still it the V-belt.
-- brand new kevlar v-belt to OEM specs/length (e.g. its not old, stretched, worn, etc). I just replaced it as I thought that was the issue (stretched V-belt). But the that didn't fix the problem. Still slack in the V-belt.

My guess is I need to adjust the idler arm. But I'm not definitive that's its. So I'm looking to you experts on here.

What do I need to do check, look at/inspect, or do to begin to troubleshoot this problem?

Your help is appreciated and I thank you in advance for your thoughts/insight/suggestions.

Leave off the belt cover and post a picture of the belts and idler with the auger engaged and disengaged. A lot of times that's easier to work with.

Perfect. Here're pics. Again the sheave is spinning but the belt isn't tightening enough when the idler arm is engaged to get the V-belt to spin. One pic is the auger control lever disengaged (more slack in the belt) and one pic is with it engaged (less slack in the belt). Its almost as if the belt is too long, but the previous belt had slack as well. Also, my thrower model is Ariens 924505 and the part I bought is this one: https://www.vbeltguys.com/products/7...-kevlar-v-belt

so it claims its a direct replacement.

Yep. There's no tension on the belt. You need to take those idlers off and check them. It looks like there may be a bearing out.

And I would double check the belt for ;your model with the serial number. There are four or five belts for that one. Your belt may possibly be too long. The third digit from the right is different for each of them.

Looks like the belt is a little too long. It could be possible to adjust the idler to take up some of that slack if you have the clearance. Might want to measure the old belt and the new belt to see how much they vary in length also.

I agree the belt looks to long and the pulleys look bad
