• Unhook the idler spring from the hex bolt on the
auger housing. See Figure 14.
• Back out the stop bolt until the support bracket
rests on the auger pulley.
NOTE: Loosening the six nuts that connect the frame to
the auger housing may aid in belt removal.
• Lift the rear auger belt from the auger pulley, and
slip the belt between the support bracket and the
auger pulley. Repeat this step for the front auger
belt.
• Replace both auger drive belts by following
instructions in reverse order.
NOTE: If you placed plastic film under the gas cap, be
certain to remove it before operating the snow thrower.
Drive Belt
• Follow the first four steps of the instructions for
servicing the auger belts.
• Pull the idler pulley up and lift the belt off the wheel
drive pulley and friction wheel disc. See Figure 14.
• Back out the stop bolt until the support bracket
rests on the auger pulley. See Figure 15.
• Slip the belt between the friction wheel and drive
disc. Remove and replace the belt. Reassemble
following the instructions in reverse order.
NOTE: The support bracket must rest on the stop bolt
after the new belt has been assembled.

Replacing Friction Wheel Rubber
The rubber on the friction wheel is subject to wear and
should be checked after 25 hours of operation, and
periodically thereafter. Replace the friction wheel
rubber if any signs of wear or cracking are found.
• Drain the gasoline from the snow thrower, or place
a piece of plastic under the gas cap.
• Tip the snow thrower up and forward, so that it rests
on the housing.
