Snow blower shear bolts (also called shear pins) are crucial safety components designed to protect your snow blower’s auger and drivetrain from damage when hitting heavy obstructions like ice, rocks, or debris.

Purpose:

• They are engineered to break under excessive force, preventing damage to the auger, gearbox, or other drivetrain parts.

• By shearing, they act as a mechanical fuse, saving you from costly repairs.

How They Work:

1. When the auger hits a hard object, the bolt snaps at a predetermined torque threshold.

2. This disengages the auger or impeller, stopping the transfer of force to internal components.

3. Once broken, the shear bolt must be replaced before resuming operation.

主要功能：

• 材質： Made from softer metals (often grade 2 or 5 bolts) to ensure they break before other components.

• Precision Strength: Designed to shear at a specific load, matching the machine’s tolerance.

• Standard Sizes: Common sizes include 1/4″-20, 5/16″-18, or 3/8″-16 (varies by model).

• Shouldered Design: Some have an unthreaded section to ensure they break in the correct spot.

Replacement Tips:

• Always use OEM or exact-spec shear bolts—regular bolts can damage the machine.

• Carry spares—they’re inexpensive and essential during heavy snow clearing.

• Check regularly—a missing or worn shear bolt can lead to drivetrain failure.

Where They’re Located:

• Typically found on the auger shaft 或 impeller shaft, securing the rotating components to the drive mechanism.

If your snow blower suddenly stops throwing snow but the engine runs, a broken shear bolt is often the culprit. Replacing it is usually a quick fix!
