Drain the gasoline from the snow thrower, or place a piece of plastic film under the gas cap.

Tip the snow thrower up and forward so that it rests on its auger housing. Refer to Figure 9.

Remove the six self-tapping screws from the frame cover underneath the snow thrower.

Roll the front and rear auger belts off the engine pulley. See Figure 17.

Unhook the idler spring from the hex bolt on the auger housing. See Figure 18.

Back out the stop bolt until the support bracket rests on the auger pulley. See Figure 19.

Drive Belt

Follow the first six steps of the instructions for servicing the auger belts.

Pull the idler pulley up and lift the belt off the engine pulley and friction wheel disc. See Figure 17.

Back out the stop bolt until the support bracket rests on the auger pulley. See Figure 19.

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. See Figure 19.
