Are all snowblower shear bolts the same?
All two-stage snow blowers have at least one shear pin on each side of the auger gear case. A shear pin is different from a regular bolt because it is designed to break, or “shear,” which in this case is a good thing.
Why does my snowblower 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.
What grade should a shear bolt be?
Registered. Normally shear bolts are Grade 2 and there is no soft grade #5 as it is either a grade #5 or not.
Should shear bolts be tight?
Oh yeah, a shear bolt should stay fairly tight. If it’s coming loose, even with a lock nut, just double nut it. It will not loosen. If it is coming loose it’s usually because of #1, which is allowing it to work back and forth in the hole.
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.
Can you use regular bolts as shear pins?
Never use a regular bolt to replace a “shear pin” bolt! It is with the failure of the shear pin bolt that potential damage is not extended to your snow blower drive train system. The shearing of the shear pin bolt releases all force off the snow auger allowing it to no longer be driven but to spin freely.
Can a grade 8 bolt be used as a shear pin?
No. Damage to the unit will occur if a higher grade bolt is used in place of the original.
How do you get a stuck shear pin out?
If it is a shear pin it should be fairly soft. File the side that is the least peaned and use a drift punch slightly smaller than the hole the pin passes through to knock it out.
Where are shear pins used?
Shear pins as safeguards As a mechanical sacrificial part, it is analogous to an electric fuse. They are most commonly used in drive trains, such as a snow blower’s auger or the propellers attached to marine engines. Another use is in pushback bars used for large aircraft.
How are shear pins rated?
Shear pin torque limiters are a simple, cost-effective design for protecting equipment from torque overloads. The accuracy of a shear pin design’s rated torque, for example, is typically in the range of ±20 percent, while the rated torque accuracy of a ball detent torque limiter is in the range of ±5 percent.
How big of a shear bolt do I need for an 18 ” Auger?
These bolts are 3/8″ x 3″, ungraded or up to grade 2 bolts, with unmarked heads. These bolts are for use with up to a 12″ diameter auger bit. If you have a 6900HD or 7500 Everything Attachments PHD with 18″ auger, you will need a grade 5 shear bolt.

How does a Honda hs928 snow blower work?
The speed control hydrostatic drivetrain allows operators to choose their speed according to the snow conditions. The HS928 is also equipped with reversible two position skid shoes that give twice the life from one set and can be changed according to snow conditions.
