Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I am not experienced with snow throwers...I recently purchased my first one...used Ariens ST1032...I have seen some topics on shear pins...and how they break from time to time..and how it is good to have

extras on hand...could someone help me out in telling me (or showing me in pcis) what a shear pin does exactly...and where it is / what it looks like on this model? How will I know when one has broken?

Thanks.

The URL at the bottom of the post links to a site which will explain how to get a manual for your machine.  You can get owners, parts and service manuals for your machine.  Lots fo good reading for your machine.  

Here is a link to download the manuals for yours.

Another thing with the sheer bolts, remove them now and see if you can spin the "spiral things".

There are usually called augers, rakes or collectors.

Your sheer bolts should be in the center of them.

If they spin just fine, then grease them up, spin them some more after greasing, and put the sheer bolt back in.

Without an exact model number, we can't tell you what sheer bolt is proper for your machine.

Here is what mine uses.

You can see in addition to being a softer metal, it also has 2 grooves cut into it.


If you pull the bolts out and find that you can't spin them, that means they are rusted on the front axle shaft and they will not break when they are suppose to.
The end result is the same as if you have a hardened steel bolt in there instead of proper sheer bolts.  If you hit something that you shouldn't be hitting, you
will break something in the gear box and instead of spending $1 for a new bolt, you will be spending $150 for a new gear box.

Here is a picture that may help



Shear pins are A. B is grease nipples on this machine.
