Troy-Bilt Shear Pin

A shear pin acts as a safety fuse for your snow blower. It is designed to break intentionally when the auger hits a hard obstruction, like a rock or ice chunk, which prevents the force of the impact from traveling up the drive shaft and destroying your machine's gearbox.

These pins are designed for most two-stage snow blower models. To be certain, check your owner's manual for the specific part number; these pins are direct replacements for OEM part numbers 738-04124 and 738-04124A.

Shear pins are consumable items that break frequently if you clear gravel driveways or live in areas with heavy, icy snowfall. Having a bulk supply on hand ensures you won't have to stop clearing your driveway mid-storm just because you ran out of replacements.

No, you should never replace a shear pin with a standard hardware store bolt. A standard bolt is often too strong and will not break when it should, which can lead to catastrophic and expensive damage to your snow blower's gearbox or auger assembly.

Installing a shear pin is a straightforward maintenance task. You typically just need to align the holes in the auger shaft with the auger blade, insert the new pin, and secure it with the provided cotter pin or locking nut.
