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.

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