Craftsman Snowblower Shear Pin Parts

Craftsman Snowblower Shear Pin Parts

Shear pins are the unsung heroes of snowblower reliability. These small but critical safety pins break on purpose when the auger jams on ice, rocks, or hidden debris — protecting your snowblower's transmission and gearbox from catastrophic damage. When a shear pin snaps, your auger stops turning, and you'll know immediately that something is stuck. It's a designed failure, not a defect.

Craftsman snowblowers use shear pins on both single-stage and two-stage models. Keep a 5-pack in your equipment shed before winter hits. When one breaks, you'll be grateful to have spares on hand — and installation takes just minutes.

• Auger won't turn: shear pin has broken; motor runs but no auger rotation
• Sudden loss of throwing power: partial break or bent pin; auger turning but sluggish
• Grinding or rattling from auger housing: broken pin fragments; remove and replace both pins
• Auger jammed on ice or rock: the pin did its job; clear jam, replace pins, and resume
• Preventive maintenance before winter: replace worn or corroded pins; fresh pins support reliability

Craftsman Snowblower Shear Pin FAQs

What's the difference between a shear pin and a shear bolt?

Craftsman uses both names interchangeably — they're the same part. The pin slides through a hole in the auger shaft and gearbox coupling. When impact force exceeds the pin's shear strength, it breaks cleanly, stopping the auger quickly and protecting expensive transmission parts. Always replace with OEM Craftsman pins rated for your model's power level.

Why do I keep breaking shear pins?

Frequent breaks usually mean wet, heavy snow is hitting compacted ice underneath — or the auger blade is hitting rocks or ice chunks. Clear the chute and intake area before each use. If breaks persist on light snow, the pin may be undersized (aftermarket pins are sometimes weaker). Switch to genuine Craftsman pins. Also check that both pins match — a mismatched pair can cause one to break prematurely.

Can I use a regular bolt instead of a shear pin?

No. A regular bolt won't break at the right force threshold — it will either shear too easily (stopping the auger on wet snow) or too late (allowing transmission damage). OEM shear pins are engineered for your specific snowblower's auger mass and engine torque. Use only Craftsman-spec pins.

How do I find my Craftsman snowblower model number?

Look on the yellow decal on the frame, usually on the side or rear of the housing. The model number starts with "88" (e.g., 88172, 88397, 88956). Enter it into our Craftsman Snowblower Shear Pin Parts finder to confirm the correct pin size and part number — pin diameter and length vary by model.

Craftsman Snowblower Model Number: Where to Look

Craftsman typically prints the snowblower model number on a yellow identification decal attached to the frame, often along the side or rear of the housing. If it is not there, check beneath the handle panel or near the engine for another label. Clean away snow, dirt, or oil so every digit is readable, and copy the complete model number exactly as shown. Type it into the model number search to narrow the full Craftsman snowblower parts catalog to parts matched to your entire machine. This quick step helps you avoid comparing incompatible parts and puts the correct options in front of you faster, so you can order with confidence knowing the fit is right.
