Why do I keep breaking shear pins?
However, if the workload is too much for the augers to handle, a shear pin can break. A shear pin is a safety mechanism that is designed to break if the torque on the augers becomes too great. This way the auger’s driveshaft won’t break if you run over a curb, newspaper or hidden rock.
Simply so, Are all snowblower shear pins the same size? 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.
How do you fix a shear pin on a snowblower?
Subsequently, How do you align shear pins?
Is a clevis pin the same as a shear pin?
Not a shear pin. Clevis pin or picker pin. Basically a 3/8 straight pin that a cotter key goes through to hold the pin in. Might try some grade 5 bolts.
How do you get a stuck shear pin out?
Should auger spin freely?

How do I change my auger shear pin?
Do Single stage snow blowers have shear pins?
Single stage walk-behind blowers with their forgiving rubber paddles used in lighter snow removal work will not have shear pins or bolts.
What is a shear pin made of? Shear pins are available. Materials include aluminum, brass, copper, bronze, steel and stainless steel. Drilled, machined, rolled, grooved and screw machined ground pins are available. Other types of pins include fastening, assembly, clevis, dowel, cotter, escutcheon, spring, quick release and taper.
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.
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 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.
Can you reuse prop cotter pins?
Look closely for any cracking, If there is none, you can safely re-use it. There will be some uneven bends in it from when you straightened it to pull it out – these are no problem. If it looks beyond use, I’d go to NAPA or a similar quality store and buy one of their stainless cotter pins in the appropriate size.
What are shear bolts on a snow blower? 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.
What is a 2 stage snow blower?
Two-stage snow blowers have power-assisted wheels which help to maneuver the snow blower and assist the user when clearing snow on slopes and large areas. Two-stage snow blowers come equipped with a variety of features to make removing snow easier, quicker and more comfortable.
How do you free up a rusted snowblower auger?
How do you replace a shear pin on a Toro snowblower?
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.
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.
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.
