of snow thrower operation. Replace if either shows signs of wear and
tear. To remove and replace either the auger belt or the drive belt,
follow the steps below and then proceed to the specific steps listed
under respective sub-headings.
1. Remove belt cover by removing the two self-tapping screws that
secure it to the snow thrower housing. See Figure 17.
2. Drain the gasoline from the snow thrower, or place a piece of
plastic under the gas cap. Carefully tip the snow thrower up and
forward, so that it rests on the housing. Remove the self-tapping
screws from the frame cover underneath the snow thrower and
move the frame cover away. See Figure 18.
