Replacing Shear Pins
A WARNING: The auger and impeller rotate at fast speeds that can cause
damage or even amputation to body parts. Even if you do not see the auger or
impeller rotating, they may start at any time if the engine is running.
Always turn off the engine before attempting to clear any clogs or jams.
Keep hands and feet away from rotating parts while the engine is running.
Do not wear loose fitting clothing that can become entangled in rotating
parts.
TIMELINE: When Broken
The snow thrower contains two shear pins, one on each end of the auger shaft as
shown in figure 24. A clog or jam in the auger may cause one or both of the shear
pins to break. This is a safety mechanism to protect the rest of the snow thrower from
overload and damage. The snow thrower comes with two replacement shear pins. To
order more shear pins, please call our customer service line.
To replace a shear pin:
1. Turn off the engine and wait for all moving parts to come to a complete stop.
2. Remove any remnants of the broken shear pin. You may need to unscrew the nut
from the broken shear pin.
3. Place a new shear pin through the hole in the auger shaft and tighten using the
shear pin nut.
