Shut off the fuel to prevent spillage. Drain the fuel or unscrew the gas cap and stretch a clean plastic sandwich bag over the filler neck. Hold the bag in place by screwing the fuel cap back on. This will keep fuel from dripping out of the gas cap vent.
Tip the snow blower forward so the top of the bucket is on the ground. Prop it with blocks if needed.
Remove the bottom plate. Remove the 2 bolts that hold the universal block to the chassis from underneath.
The chute crank will now be movable and easier to work on. Using a suitable punch and hammer drive out the roll pins holding the gears on. After the 2 pins are out the gears will come out of the universal block. Now the new gears can be slipped into place. Align the holes and drive the pins back in. If you are replacing plastic gears there may be a spacer that will no longer be needed.
Bolt the universal block back on the chassis, check for any binding and adjust as necessary.Reinstall the bottom plate. Tip the snowblower back down on it's wheels, and remove the plastic bag under the gas cap.
