Question for you.....I have a 921037 Ariens, and I noticed the gearbox shaking a fair bit, while I had the Auger handle engaged and tied down with a ziptie....motor running. I remved the belt cover, and let it run as well, noticing that that pulley on the bucket also had a fair bit of side to side wobble. I split the blower in two, checked the pulley and bearing...both fine. I removed the pulley and reseated it...it did make some difference in the wobble....better by 30% or so. My question is.....is this normal with Ariens? I've watched several videos on You Tube of belts running, and many of the pulleys seem to have some degree of wobble while running. Does anyone know what the specs that Ariens will allow? I am wondering if my impeller shaft to the augers is out of range. It doesn't look like it's hit anything. Any help/advice/or ideas would be appreciated.:smile2:

Is the gearbox support centered so that the augers have the same clearance? Is the gearbox support tightened down fully against the bucket and the side of the gearbox? Do you feel a vibration through the handles when the auger is running since the impeller could be damaged.

Good Morning Town! The gearbox and sidebolts for the Auger are fully tightened....that's the first thing I checked. However,I did not check to see if the gbox support is centred...I will do that today. I can tell you that the augers run fine, no hitting or grinding, and I don't feel an unusual amount of vibration.
I attributed the shaking to the pulley on the bucket. The blower works well, doesn't throw belts, and the augers don't slow down or stall in heavy snow. I guess it's just me being picky.:smile2: I just wondered if others noticed the same thing, or this might be inherent to the brand/machine?

My machine has no vibration at the handles. There is no difference with the engine running at max and impeller/augers stationary or engaged or when blowing snow. The reason I asked about the possible impeller damage is that the other day I had a large chunk of ice going around with the impeller (6 blade) that caused a vibration. I stopped the engine and checked it out immediately, the ice was too large to exit through the chute opening. I pulled it out and the machine was back to its old smooth ways again.

On my old Craftsman the auger support bushings at the end of auger shafts wore out, more on one side than the other, and that caused the unsupported gearbox to move erratically. I think that caused some vibration too.

Thinking more about this, I just might pull the augers right out of the bucket,just to see if all is well with the auger bearings, and have a good look at the rakes and impeller, once the weather is a bit more forgiving. We've had a cold snap here in Sask for the last month or so with night temps -43C on average. Thanks for the great advice.:smile2:
