WARNING: Do not attempt to change the
auger belt without the help of an assistant. It
is very important that one person, standing
at the operating position, firmly hold the
snow thrower housing to prevent it from
tipping while the other person replaces the
belt. Failure to comply with this may result
in injury.
Figure 18
4. Standing in the operating position, lift up on the
handles and pull the frame assembly rearward.
The frame and the housing will separate, and
the rear auger belt will come off the pulley.
Maintain control of the frame assembly while
pulling it.
5. Remove the two belts from the two engine pulleys.
For location of the pulleys, see Figure 19.

6. To remove the front auger drive belt, push the

auger drive belt from the front auger pulley.

7. Place new belts on the two auger pulleys making
sure that the front auger belt is under the belt
brake. Route belts under and to the left of the
flat idler pulley. Hold the belts upward in this
position.
8. While lifting up on the handles, bring the frame
assembly close to the auger housing, and place
the two belts on the front and rear engine
pulleys. See Figure 21.

9. Level the frame assembly and tip the auger
housing forward to align studs with the
corresponding holes on both sides of the frame
assembly. See Figure Figure 18. Push the frame
assembly fully on to the studs.
NOTE: Use care to avoid pinching the control cable.
10. From the frame assembly side, insert six lock
washers and hex nuts on to the studs . These
pieces of hardware were removed earlier.
Tighten the nuts securely.
11. Reinstall the belt cover on the front of the engine
with the two self-tapping screws and flat
washers.
12. Reattach the chute crank to the chute assembly
with the hairpin clip and flat washer.
NOTE: Make sure that the auger cable is routed in
front of the belt.
