How to replace a snowblower friction disc

Pull the spark plug wire straight up and off the plug.

Tip the snow blower forward so it rests on the auger housing. Remove screws that secure the frame panel located between the wheels. Detach the panel to access the drive system components.

Remove the bolts that secure each wheel to the axle. Pull off both wheels.

Hold the hex shaft stationary with a 13/16-inch open-end or adjustable wrench. Remove the mounting nut using a ratchet and 1/2-inch socket or wrench.

Lightly tap the left end of the hex shaft to push the bearing out of the right side of the frame. Remove the bearing. Carefully pull the hex shaft down and to the left. Pull the friction disc off the shaft.

Remove any rust from the shaft and clean it thoroughly. Apply anti-seize compound to the shaft. 

Slide the new friction disc onto the hex shaft. Position the friction disc properly and push the hex shaft back into the bearing on the right side of the frame. Reinstall the hex nut and tighten.

Push the wheels onto the axle. Reinstall the washer and mounting nut on each wheel. Tighten the mounting nuts securely on the axle.

Position the frame panel and line up the mounting holes. Insert the mounting screws and tighten firmly. Pivot the snow blower upright so it rests on its tires.

Reconnect the spark plug wire. Fill the tank with gas and test the snow blower.
