The model is a 922003. It runs fine, but the auger wont turn. it looks like the belt is loose, but I keep reading about these shear pins.. any help in where to start would be great. I have no repair manual, and am a beginner in fixing these kinds of things.
Just finished repairing my ariens, 6 years old with aluminum gear box. Same problem encountered. The problem turns out to be the BRONZE gear driven by the worm shaft. Shear bolts did not shear and bronze gear broke about 5-6 teeth. This is why you can move the auger a half turn or so, there are no gears in one area of the gear and as the gear turns to engage the worm drive it will stop. The fix: the cast iron replacement from ariens! About $200 including shipping, got mine from Jack's Small Engine (MD). Fairly easy repair if you are mechanically inclined. Buy yourself a set of roll pin extractors ($20 from Sears), new roll pins, new woodruff key for shaft. You will also probably have to press 2nd stage impeller from shaft with hydraulic press & heat (took mine to my local auto garage). What stinks is ariens seemed to have admitted the design problem with the aluminum gearbox, yet won't help with repair cost! Anyways, I learned a lot about my snowblower for future repair (belt replacement)!

Re: ariens snowblower auger wont turn
With the engine off check to see if the belt tightens up enough when you engage the auger, if it does will have to check to see if there is a filler plug on the gear box if there is than pull the plug (if there is 2 plugs then pull the top one) fluid should drizzle out if nothin comes out than you need to add fluid. you can get a breakdown of your machine at Ariens.com. As far as the shearpins go, there soud be 2 on the auger shaft itself (1 on each side where the auger paddles are). I think it's going to be either the belt needs adjusting or something to do with th gear box.

Your front end is jammed. Its either frozen or there is a rock or something jamming it up. Before you start engine reach down chute and turn back impeller that throws the snow out of blower. Should turn freely. when its free its fixed. You will probably need a new belt.
Hi, I will try to help you with this problem. I think the problem might be an adjustment issue. If you take the cover, usually plastic, situated just in front of the engine housing, you will see the belts and pulleys. Without the engine running, press on the auger/impeller lever, and if you look inside you should see how the belt is made to engage the auger pulley. Probably by an idler pulley that pushes on the belt to make it tight to turn the big pulley. That is the most popular way, it is to loosen the bolt on the idler pulley and push it towards the belt so it applies more pressure to the belt to turn the auger pulley and tighten the bolt. There could also be an adjustment on the linkage that might be adjustable. Another possibility is that the belt is worn and is riding on the bottom of the pulleys therefore not providing enough friction to turn the pulleys properly. I think if you take a good look at that system you will comprehend it. Hope this is helpful. All the best and good luck. I will gladly answer any other questions.
Hi, The blower spins at full speed? If it does the belt, pulley, and shaft are good. Look at the shaft from the fan to the gear box while it's running and that shaft should be turning at the speed of the fan.
If the blower spins at full speed and the auger doesn't the most likely problem is the worm gear transmission from the blower shaft to the auger shaft.
A good way to visually inspect this is: With the machine turned off and the spark plug wire unhooked go to the front and try to rotate the auger by hand. If the gear box is good you will only be able to move the auger less than an inch. If the box is bad you will be able to move the auger a lot farther. While you are there recheck your shear pins.
You can also remove the blower drive belt and have someone turn the pulley by hand while you watch the auger. Put resistance on the auger with your gloved hand. If the box is good the auger will move smoothly in you hand. If it is bad, it will ****, move roughly, or stop.
While the other person is turning the pulley and you have some resistance on the auger look closely at the shaft running from the gearbox back to the blower. On some models there is a connecting sleeve and the roll pin that connects the sleeve to the shaft and gearbox will break.
If the gearbox is bad, it will have to be replaced as a complete unit.

Sounds like you have a broken or partially broken shear pin in the auger.Check along the auger[machine off]and see if there is what looks like a bolt anywhere along the auger shaft.If there is [and there will be] remove and inspect it and you will see why the auger is not working.Next time,never clean out a chute or auger while the engine is running,people loose limbs this way.
Looks to me like your second stage is not working. If the auger is turning fine, look and see if the secondary thrower is turning. Probably a shear bold on one or the other is broken. Easy fix, but do not put your hands in there when the machine is running!
