The belt brake should move outward and lift the front auger drive belt from the front auger pulley. • Place new belts on the two auger pulleys making sure that the front auger belt is under the belt brake. Route belts under and to the left of the flat idler pulley. Hold the belts upward in this position. Figure 15 • While lifting up on the handles, bring the frame assembly close to the auger housing and place the two belts on the front and rear engine pulleys. See Figure 16. Figure 16 • Level the frame assembly and tip the auger housing forward to align studs with the corresponding holes on both sides of the frame assembly. NOTE: Use care to avoid pinching the control cable. • From the frame assembly side, insert the six lock washers and hex nuts previously removed onto the studs. Tighten nuts securely. See Figure 14. • Reinstall the belt cover on the front of the engine with the two self-tapping screws and flat washers. NOTE: Make sure that the auger cable is routed in front of the belt.

Self-Tapping Screw Belt Cover Hex Nuts & Lock Washers Remove Belt Remove Belt Idler Pulley Push Frame Assembly Push Auger Assembly 14 • Remove the plastic belt cover on the front of the engine by removing the two self-tapping screws. • Tip the snow thrower up and forward, so that it rests on the housing. • Remove six self-tapping screws from the frame cover underneath the snow thrower. • Pull the idler pulley away from the drive belt and remove the belt from the engine pulley. • Working from the underside of the frame, slip belt between the friction wheel and the friction wheel disc. You may have to twist the belt flat in order to slide it through the clearance between the friction wheel and the friction wheel disc. Remove and replace the belt. Reassemble following the instructions in reverse order. See Figure 17. Figure 17 Servicing 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 six screws from the frame cover underneath the snow thrower. • Remove the left wheels from the axle. • Remove the four screws securing the left drive cover to the frame. Remove the drive cover from the side of the frame. See Figure 18. • Holding the friction wheel assembly, slide the gear shaft out of the left side of the unit. The spacer on the right side of the gear shaft will fall and the sprocket should remain hanging lose in the chain. See Figure 18. Figure 18 • Lift the friction wheel assembly out between the axle shaft and the drive shaft assemblies. • Remove the six screws from the friction wheel assembly (three from each side). Remove the friction wheel rubber from between the friction wheel plates. See Figure 19. Figure 19 Friction Wheel Friction Wheel Disc Drive Belt Drive Cover Friction Wheel Pin Spacer Sprocket Gear Shaft Friction Wheel Rubber Screws Screws Friction Wheel Plates Hub • Reassemble new friction wheel rubber to the friction wheel assembly, tightening the six screws in rotation and with equal force. • Insert the pin from the shift arm assembly into the friction wheel assembly and hold assembly in position. Refer to Figure 18. • Slide the gear shaft through the left side of the housing and through the friction wheel assembly. • Insert the gear shaft through the sprocket and the spacer. Make certain that the chain engages both the large and the small sprocket. Refer to Figure 18. NOTE: If the sprocket fell from the snow thrower while removing the hex shaft, place the sprocket on the hex shaft. Position the hex hub of the sprocket toward the friction wheel when sliding the sprocket on to the hex shaft. • Align the gear shaft with the right hand bearing and carefully guide the left hand bearing into the left side of the housing. • Reassemble the drive cover with the four screws that were previously removed. NOTE: If you placed plastic under the gas cap, be certain to remove it. Off-season Storage WARNING: Never store the machine or fuel container indoors where there is an open flame, spark, or pilot light such as on water heater, furnace, clothes dryer, or other gas appliance. WARNING: Drain fuel into an approved container outdoors, away from an open flame. Allow engine to cool. Extinguish cigarettes, cigars, pipes, and other sources of ignition prior to draining fuel. Fuel left in engine for extended periods deteriorates and will cause starting problems. If unit is to be stored over 30 days, prepare for storage as follows: • Remove gasoline from carburetor and fuel tank to prevent gum deposits from forming on these parts and causing possible malfunction of engine. • Run engine ...
