Stens Shear Pin

A shear pin is designed to be the weak point in your snow blower's drive system. If your auger hits a solid object like a rock or ice chunk, the pin snaps to prevent that force from traveling up the shaft and destroying your expensive auger gearbox.

This pack is designed for MTD models manufactured from 2005 and newer. It serves as a direct replacement for OEM part numbers 738-04124 and 738-04124A, so check your owner's manual for those specific part numbers to ensure compatibility.

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 costly damage to your snow blower's gearbox.

Shear pins are consumable parts that are meant to break. Having a shop pack on hand ensures you aren't stuck in the middle of a blizzard with a broken machine, waiting for a replacement part to arrive.

This shop pack includes the shear pins themselves. You will typically reuse the existing lock nuts from your snow blower, but it is always a good idea to inspect your old nuts for wear or rust before reinstalling.
