When it’s safe, visually inspect the augers. If you don’t see the shear pin head or nut and you can manually spin the auger along the auger shaft, you broke a shear pin.
How tight do you tighten shear pins? It should be a locking type nut and all you need to do is snug it down to where it contacts the auger sleeve and stop there. Don’t snug it down to where the spindle turns with the shaft.
Similarly, Are all snow blower shear pins the same? There are three basic sizes of shear bolts, and it’s important to select the correct one for your snowblower to ensure it fits and works correctly. Brass 1/4″ shear bolts are most commonly used on smaller, entry-level snowblowers. Black 5/16″ shear bolts are for larger mid-grade snowblowers.
Why is my auger not turning?
How do you align shear pins?
Should my snowblower auger spin freely?
A snowblower auger should not spin freely when the auger control lever is off. A free-spinning auger is a symptom of broken shear pins. Shear pins are a fail-safe feature, designed to break when the auger hits a solid object.
What are shear pins made out of? Material. A shear pin could potentially be made from any material although metal is the most common. When making a metal object for a mechanical application, an alloy and tempering is usually selected to make the construction resistant to damage.

Should auger spin freely?
A snowblower auger should not spin freely when the auger control lever is off. A free-spinning auger is a symptom of broken shear pins. Shear pins are a fail-safe feature, designed to break when the auger hits a solid object.
What grade is a shear pin? Registered. Normally shear bolts are Grade 2 and there is no soft grade #5 as it is either a grade #5 or not.
Why does my snowblower dies when auger engaged?
It’s known as fuel starvation. A dirty carburetor is the most common root cause of fuel starvation. Tiny fuel passages inside your carburetor become clogged and restrict gas flow. When the auger is engaged, the engine demands more fuel, when the carburetor can’t supply it, the engine simply stalls.
Why is my snowblower auger not turning? A broken shear pin is the most common reason the snowblower auger won’t turn properly so replace any broken shear pins. Worn or loose belts also prevent the snowblower auger from spinning. Check and adjust the belts and replace any broken or worn belts when you see the snowblower auger not turning.
How do you free up a seized auger on a snowblower?
Should snowblower impeller spin freely?
A snowblower auger should not spin freely when the auger control lever is off. A free-spinning auger is a symptom of broken shear pins. Shear pins are a fail-safe feature, designed to break when the auger hits a solid object.
What is shear pin coupling? GBM Shear Pin Coupling are used to control the rated torque. The pin shears off incase the torque of the whole coupling exceeds the rated torque.
How fast should the auger spin on a snowblower?
So about 2 revolutions per second.
Can you turn snowblower auger by hand?
The impeller turns and the shear pins on the impeller shaft are ok. All of the auger shear pins are ok too. You can turn the impeller by hand, but the auger seems to be turning independently.
Why does my auger keep spinning? It is probably that the auger adjustment was set to account for some stretching in the old belt. When you replaced the belt the adjustment was then needed to account for the now-shorter belt. Look in the manual to see how to adjust the auger setting.
Why is my Auger not turning?
What grade metal is a shear pin? Registered. Normally shear bolts are Grade 2 and there is no soft grade #5 as it is either a grade #5 or not.
What material has the best shear strength?
STEEL
| description | hardness | shear Strength PSI |
|---|---|---|
| ASTM A-36 | BHN 119-159 | 58-80,000 |
| 45-50 Carbon HR Sheet | BHN 200 | 80,000 |
| Spring Steel 1074, 1095 Hardened to Spring Temper | Rc 45-50 | 200,000 |
| COR-TEN Steel | BHN 120 | 55,000 |
What kind of metal are shear pins made of? Pins for Shear Hubs
Pins will be either 12L14 or 1215 carbon steel.
