If the pin is broken the auger will have rotated on the shaft to some degree. You must line up the hole in the auger with the hole in the auger shaft and tap out the broken piece with a drift or punch. Do it using as little force as possible with as small a hammer as possible. You need not take off the blower housing.

Likewise, what happens when a shear pin breaks?
Broken shear pin or bolt. The shear pin and bolt fasten the augers to their drive shaft. They're designed to break if your snow blower's auger hits a large rock or chunk of ice to protect the engine from damage. If the shear pin or bolt breaks, the auger is unable to turn.
Subsequently, question is, why do shear pins break? Shear pins. Notice the grooves in the pins where they will break off to prevent damage to your auger shaft and gear case. A shear pin (sometimes called a shear bolt) in a snow blower connects the auger to the shaft. It is designed to break away in case foreign objects come in contact with the moving parts.
Also question is, how do I know if my shear pin is broken?
Look at the auger's shaft to locate the shear pins. The shear pins connect the auger shaft and the driveshaft. If a shear pin is broken, there could be pieces of it still lodged in the shear pin holes, or the entire shear pin could be missing. Use a hammer and punch to remove shards of the shear pin from the hole.
How do you remove a shear bolt?
Placing the tip of the tool on the outer edge of the shear head bolt and depressing it while applying counterclockwise pressure will quickly loosen them. Using a rubber pencil eraser against the top of the bolt and continuing to rotate counterclockwise will remove the bolt.

A shear pin is a mechanical detail designed to allow a specific outcome to occur once a predetermined force is applied. It can either function as a safeguard designed to break to protect other parts, or as a conditional operator that will not allow a mechanical device to operate until the correct force is applied.How tight should a shear bolt be?
Product Support - How tight does the bolt holding the blade need to be on my tractor? Blade bolts should always be torqued to the proper range. For the 7/16 GR 8 bolts (5/8" wrench) used on some mowers, torque to 45-55 ft lbs.What is a snow blower shear pin?

It can either function as a safeguard designed to break to protect other parts, or as a conditional operator that will not allow a mechanical device to operate until the correct force is applied.Why are shear pins made from high carbon steel?
Machinery such as farm equipment and packaging machines uses shear pins made from high carbon steel to prevent overload if something becomes jammed. High carbon steel is chosen as a material for use in shear pins because it is a strong metal so will fail at a much higher load but it is also brittle.How do shear pins work?
A shear pin is a mechanical detail designed to allow a specific outcome to occur once a predetermined force is applied. It can either function as a safeguard designed to break to protect other parts, or as a conditional operator that will not allow a mechanical device to operate until the correct force is applied.Why does my snowblower keep breaking shear pins?
The snow blower's augers help you churn through hard-packed snow and ice. However, if the workload is too much for the augers to handle, a shear pin can break. This way the auger's driveshaft won't break if you run over a curb, newspaper or hidden rock.Do Toro snow blowers have shear pins?
Toro two-stage snowblowers do not use shear pins. The commercial-grade gear case makes the need for a shear pin unnecessary. If the auger hits an obstruction or is over-loaded with snow, the engine may shut off, so that you can remove the key, clear the obstruction safely with a stick and get back to work.Should a snowblower auger be turned by hand?
Snow Blower Auger won't Turn By Hand. The only way to turn the auger is by turning the impeller (the "fan" at the bottom of the chute).Why is my Auger not turning?
A broken shear pin is the most common reason the auger won't turn properly so replace any broken shear pins. Worn or loose belts also prevent the auger from spinning. Check and adjust the belts and replace any broken or worn belts. Check the auger drive cable and adjust it if loose or replace the cable if it's broken.Why did my snow blower stop working?
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. This sticky fuel can clog up the carburetor and cause the engine to stall. If the carburetor is clogged, try cleaning it with carburetor cleaner.How often should you change snowblower spark plug?
Spark plugs need to be replaced once per season, or after 100 hours of use. It's a good idea to clean your spark plug every 20-30 hours of use and check its gap. This way it stays clean, and if it needs to be changed sooner, you'll know.How do you troubleshoot a snowblower?
Snow Blower Problem #1 – Snow Blower Not Starting- Defective spark plug. Check your spark plug for any deposits, cracks or other damage.
- Old fuel.
- Clogged carburetor.
- Build-up of snow.
- Defective impeller.
- Worn scraper bar or paddles.
- Broken shear pin or bolt.
- Defective cogged or V-belt.
