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 16
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.
Remove the two belts from the two engine pulleys.
For location of the belts, see Figure 17.

To remove the front auger drive belt, push the idler

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.
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 19.

washers and hex nuts on to the studs . Refer to
