Replacing the Shear Pins or Shear Bolts
DANGER
The snowthrower contains a rotating auger and impeller
that throws snow. Fingers or feet can quickly become
caught in the rotating auger or impeller resulting in traumatic
amputation or severe laceration.
• Turn the engine OFF, wait for all moving parts to stop,
and remove the ignition key or push/pull key before
maintenance or repairs.
The augers are secured to the gear box axle with either
shear pins, shear bolts, or shear bolts with spacers. These
shear pins or bolts are designed to break if an object
becomes lodged in the auger housing. Shear pins are
installed with cotter pins. Shear bolts and shear bolts with
16
spacers are installed with nuts. The three hardware systems
are not interchangeable.
1. Turn the engine OFF. Remove the ignition key or push/
pull key.
2. Remove the remaining pieces of the hardware from the
auger shaft and discard.
3. Use a grease gun, and apply lithium grease to the grease
fitting (if equipped) on the auger shaft. Rotate the auger
to distribute the grease.
4. Align the auger holes and axle holes and install:
• a new shear pin (A, Figure 24) through the auger hole
(C) and secure with a cotter pin (B).

• a new shear bolt (A, Figure 25) through the auger
hole (B) and secure with the locknut (C).

• a new shear bolt (A, Figure 26) and space (B),
through the auger hole (C) and secure with the
locknut (D).
