Craftsman Snowblower Auger Parts

Craftsman Snowblower Auger Parts

The auger is what throws snow — when it stops working or moves slowly, your snowblower becomes a shovel. Auger belts wear out from friction and age; shear bolts or pins snap when the auger hits a rock or ice chunk (that's their job — they protect the transmission). Both are quick, affordable fixes that get you back in business fast.

Auger problems typically show themselves in two ways: the auger won't turn at all, or it turns slowly and weakly. A broken belt is the #1 culprit. Shear bolts that have snapped are the second. We stock OEM Craftsman belts and shear pin kits for most 2-stage and single-stage models — enter your model number to find the exact fit.

• Auger belt won't turn: Drive belt has snapped or slipped off; idler pulley may need adjustment or replacement
• Auger turns slowly: Belt is worn, frayed, or glazed; check tensioner and replace if necessary
• Auger jams then stops: Shear bolt or shear pin broke (this is intentional); remove jam, replace bolt, and continue
• Auger leaks oil: Seal at auger gearbox may be failing; check for debris first, then replace seal kit
• Auger makes grinding noise: Gearbox bearing wear or auger blade damage; inspect and replace as needed

Always buy shear bolts in multiples — they're consumable parts, and keeping a spare set in the shed means you're never stranded mid-storm. Browse all Craftsman snowblower auger parts by entering your model number above for help ensure compatibility.

Craftsman Snowblower Auger FAQs

What size shear bolt or pin does my Craftsman snowblower need?

Shear bolt size varies by Craftsman model — most common sizes are 3/8" × 1" and 5/16" × 1.5". Never guess on shear pin size; an oversized bolt won't break when it should (risking transmission damage), and an undersized one breaks too easily. Enter your Craftsman model number (usually on the frame under the chute) and we'll confirm the exact OEM shear bolt or pin for your machine.

Can I replace just the auger belt, or do I need to replace the idler pulley too?

The belt and idler pulley work together — a worn idler pulley will eat a new belt in one season. If the belt is frayed, cracked, or glazed, inspect the idler. If the pulley wheel spins freely and the bearing is quiet, the belt alone may be enough. If the pulley wheel is flat-spotted, wobbles, or doesn't spin freely, replace both. OEM Craftsman pulley and belt kits are the smart play.

My auger is leaking oil from the gearbox — is it a major repair?

An auger gearbox seal failure can be a DIY fix or a shop job depending on your comfort level. The seal itself is inexpensive ($15 to $40), but the gearbox may need to come off the machine. Before you replace seals, check for debris jammed in the auger housing — rocks and ice chunks can pierce the seal. If the seal itself is torn or the gearbox bearings are worn, you'll want an OEM replacement gearbox or seal kit. Model number lookup will show you the exact assembly.

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

Shear bolts are threaded fasteners that intentionally snap when the auger hits resistance (rock, ice chunk, or debris). Shear pins are non-threaded and work the same way. Craftsman uses both depending on the model — some older machines use a pin, newer ones use a bolt. Your model number determines which one you need. Always replace shear bolts in pairs (left and right side) to keep the auger balanced and prevent vibration.

Craftsman Snowblower Model Number: Where to Look

Craftsman snowblower model numbers are commonly listed on a label on the frame behind the engine, under the handle panel, or near the chute. Check the sticker for a model or model number, not the serial number, and copy every character exactly, including periods or letters. Enter that identifier in the model number search field to narrow the complete Craftsman snowblower catalog to parts matched to your machine. This filter applies to the whole unit, so it helps whether you need an auger part, belt, control, or another associated part. A precise lookup cuts down on compatibility checks and gets your repair moving sooner.
