Friction Wheel Hex Shaft Bearing _g Plate Plate Figure 32 8. Remove the bearing plate from the right side. Do not remove the hex shaft. Leave the hex shaft in position. Carefully raise hex shaft just enough to allow the friction wheel to be removed. 9. Remove the friction wheel from the hub. Slip the friction wheel toward the right off the hex shaft. See Figure 31. 10. Assemble the new friction wheel onto hub with the fasteners removed earlier. 11. Install the bearing plate onto the right side. Make sure the hex shaft is engaged with both bearing plates and that the washers and retaining ring are installed in the original position. See Figure 32. F-001087J 25 12. Fastenthe bearing plates using the four bolts removed earlier. 13. Make sure the hex shaft turns freely. 14. Check the adjustment of the friction wheel. See "How To Adjust The Friction Wheel" in this section. 15. Make sure the friction wheel and the disc drive plate are free from grease or oi!. 16. Install the bottom panel. See Figure 28. 17. Tighten the bottom bolts on each side of the bottom panel. 18. Install the top bolts on each side of the bottom panel. 19. Correct the spark plug wire. HOW TO REPLACE THE AUGER SHEAR BOLT The augers are secured to the auger shaft with special shear bolts. These shear bolts are designed to break and protect the ma chine if an object becomes lodged in the au ger housing. Do not use a harder bolt as the protection provided by the shear bolt will be lost. protect the machine, use only _ ARNING: For safety and to original equipment shear bolts. To replace a broken shear bolt, proceed as follows. Extra shear bolts were provided in the assembly parts bag. 1. Move the throttle control to the stop position. Disengage all controls. 2. Disconnect the spark plug wire. Make sure all moving parts have stopped. , Align the hole in the auger with the hole in the auger shaft, install the new shear pin and spacer. See Figure 33. 4.

Engine performance should not be affected at altitudes up to 7,000 feet. For operation at higher elevations, contact your nearest Craftsman Store. IMPORTANT: Never tamper with the engine governor, which is factory set for proper engine speed. Over-speeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, contact your nearest Craftsman Store, which has the proper equipment and experience to make any necessary adjustments. TO ADJUST OR REPLACE THE SPARK PLUG NOTE: This spark ignition system meets all requirements of the Canadian Interference-Causing Equipment Regu lations. NOTE: This engine complies with all current Australian and New Zealand limitations regarding electromagnetic interference. If you have difficulty starting the snow thrower, adjust or replace the spark plug. Replace the spark plug is the electrodes are pitted or bumed or if the porcelain is cracked. Follow the instruc tions below. To adjust: 1. Clean spark plug by carefully scraping the electrodes (Do not sand blast or use a wire brush). F-001087J 26 2. Be sure spark plug is clean and . free of foreign material. Check electrodes gap with a wire feeler gauge 5. and reset gap to 0.030" if necessary. See Figure 34. To Replace: 1. If you need a new spark plug, use only the proper replacement spark plug. 2. Set the gap to 0.030 inches. . Before installing the spark plug, lightly coat the spark plug threads with oil or grease to insure easy removal. Firmly tighten the spark plug in the engine. If a torque wrench is available, torque the plug to 18 to 23 foot pounds.

If gasoline remains in the tank, fumes may reach an open flame, spark or pilot light from a furnace, water heater, clothes dryer, cigarette, etc. NOTE: To prevent engine damage (if snow thrower is not used for more than 30 days) follow the steps below. SNOW THROWER 1. Thoroughly clean the snow thrower. 2. Lubricate all lubrication points. See the Maintenance section. , Be sure that all nuts, bolts and screws are securely fastened. In spect all visible moving parts for damage, breakage and wear. Re place if necessary. 4. Touch up all rusted or chipped paint surfaces; sand lightly before painting. . Cover the bare metal parts of the blower housing auger and the im peller with rust preventative, such as a spray lubricant. NOTE: A yearly checkup or tune-up by a Sears service center is a good way of ensuring that your snow thrower will provide maximum performance for the next season.
