New Engine Belt Has Constant Tension - Smaller Tension Pulley?

Video here:

I swapped an HM80 for an HMSK10, and the belt seems to keep driving on the drive lovejoy coupler. This makes it “snap” loudly when engaging the auger.

I can get a longer belt, but I’m wondering if a smaller tensioner pulley would be a good idea? The tensioner pulley is still engaging the belt, and I cannot back it away any further.

The reason I am concerned about a longer belt is that it seems to be flopping around when released, and with the tenioner still "pressing" in, it seems like a larger belt won't solve everything.

Has anyone put a smaller tension pulley on their machines to help with this situation?

Looks like your brake on the impeller driven pulley is not working. I can see the pulley continuing to turn when you disengage the clutch. It is supposed to stop almost immediately. Looks like the belt is slack and not tight at all.

I could be wrong but i dont think a machine of that vintage has any sort of brake. As mentioned previously, its missing the belt finger guides.

You are right, I looked up the parts manual for that machine and could not find a brake. All the machines, since 1974, that I have had include the fingers to help raise the belt higher off the engine drive pulley for the impeller pulley and an impeller pulley brake. Without the brake the engine turns the impeller and auger without drive engaged. That is so dangerous.

Sorry for my error, I thought Ariens would have been more current technology even with its older models.

My bad.

You need the Belt guides that bolt on the engine to keep it the belt curved above the pulley when disengaged. Not your engine but the same guides needed. They work.

Thanks everyone for the heads up about the finger guides. I've gone ahead and ordered a left and right one to be installed. I even did a test and pushed down (with gloves) on back of the belt to simulate the guides, and with enough pressure it stopped the belt.
