Snowblower help.


Is there another name for the Key stock? When I google it, all I get pictures of are the red key that goes into the engine. I don't think that is what you are talking about. In the pic I posted, the wheel or pully that stops turning is the one with the belt around it that looks to be a little loose, the one that is closer to the auger. The belt does not keep turning. When I engage the auger, it will start the impeller and throw very little snow and as soon as it hits a few inches, it stops altogether.

Okay... First of all, here is a picture of keystock. Most are straight, but some are half-moon, such as the one in the picture.



Second, the pulley situation... There is a pulley mounted to your engine. It has a bolt on the end of it, holding it to the shaft of the engine. The keystock will be inside that pulley, between the pulley and shaft.

Does THAT pulley stop turning when you hit snow?

If the pulley on the engine stops turning, your keystock is gone, or (possible) worse.

If that pulley continues to spin even though the blower itself stops, I'd say your belt is still not tight enough.

Since your motor pulley is still rotating (and the belt and other things downstream have stopped) it looks like the belt is still too loose.

Are there adjustments to the linkage that connects the handle levers to the idler wheels and other parts down below so by pulling the lever on the handlebars the belt becomes tighther and doesn't slip?

For example the handlebar lever connects to a cable with a screw in sleeve halfway down.

Yes, that is the pulley that stops. So the keystock is found in the gearbox attached to the auger? So, I guess I need to take that apart and see if that is broken? Again, i really appreciate EVERYONE'S help with this.

So, to clarify for my own thick skull... The pulley attached to the engine stops when you hit the snow?

As I look more closely at that pulley, I'm thinking it's possible that it is NOT a typical key stock shaft & pulley setup. It looks as though it might be a slip-clutch of sorts - where the pulley is tightened into the collar on the shaft.


So... Tighten that hex bolt on the end of the shaft. See what that does.

If the bolt won't tighten, I'd suggest removing it and slowly taking that pulley apparatus apart. I think that's the source of your problem.

I'm sure that I am doing a horrible job of explaining it, but the pulley that stops is connected directly to the auger and impeller shaft. That stops once the auger hits snow. I actually have the whole thing apart, and the friction wheel looks to be ok. What should I look for, now that it's apart? I also have that pulley apart too.

Sorry. I misunderstood you.


Turn the pulley (by hand) that is attached to the auger and impeller. Does it turn freely?

Then wedge something in the auger/impeller so it will NOT turn. Does the big pulley still turn? If yes, you have sheer pins broken, or something else.


If you have the auger & impeller housing & chute detached from the power unit, you should be able to isolate your problem from there.


I'm still suspicious of your belt tension.


Anyway, sorry I can't be more help. Without seeing it, I'm kind of shooting in the dark.

Isn't the belt tension controlled by the idler pulley and adjusted via the clutch?

I haven't had time to look at it, the past few days. I'm gonna check it out tomorrow and report back.

Yeah, that's more or less it. I guess I wouldn't call it a clutch, but it does the same thing as a clutch.

There seems to be kind of a "sweet spot" in the idler pulley adjustment. Too tight and the auger/blower assembly won't shut off. Too loose and it just doesn't operate under load.

Just to let you know... We had sunny & 63 in Omaha yesterday.

Yeah - I know. I'll pay dearly for being a smart alec!



As I continue to think about this, I wouldn't be surprised if your sheer pins/roll pins on the blower are broken (which is what they're supposed to do if a foreign object gets stuck in the blower). Mere friction will make the blower turn when it's not under load.


Let us know what you find!

If the shear pins down in the lower body are broken, the pulleys and belt will keep going and just the auger (and/or paddle/impeller) will stop.

In some cases the belt idler is on a crankshaft (cranks back and forth no more than about 90 degrees) that goes to the lower back where a cable connects to the handlebar lever. The idler tension is adjusted by adjusting the cable.

I checked the shear pins and they are ok. I read online that it could be the 2nd stage shear pins, which look to be located near the impeller, but I have yet to find them. It should be 46 degrees, here in NJ, today so that will make it easier to work outside on it. Wow, 63 degrees in December, that's crazy.

Make sure you clear paths along swales due to potential of mass melt/flooding....especially if the NE gets rain like it's supposed to this weekend.

New Joisey, huhh? This was NOT a good week to have your snowblower out of commission was it?!?!


Again, I don't know your snowblower so my advice is purely speculation. However, it is possible that your auger is running and the blower is not. From the little I've seen with the Ariens blowers, I think there are roll pins/sheer pins on the collar of the blower that slides onto the shaft that also runs the auger.


This is a weird one isn't it? Now I'm REALLY wanting to hear what you find!
