• Re-install frame cover and flip the snow thrower back to the operating position. • Wrap auger belt around the engine pulley. • Re-install belt cover with self-tapping screws removed before. Figure 25 Drive Belt • Remove belt cover by removing the two selftapping screws that secure it to the snow thrower frame. See Figure 22. • Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap. • Take auger belt off the pulley as shown in Figure 23 Self-tapping Screws Engine Pulley Auger Belt Frame Cover Shoulder Screw Spring Auger Pulley Mounting Bracket 18 • Push idler away from the chute and insert a Philips head screwdriver in the hole on the idler as shown in Figure 26. This will release tension on drive belt. Figure 26 • Pull drive belt out and away from the engine pulley to remove. See Figure 26. • Tip the snow thrower up and forward, so that it rests on the housing. Remove two self-tapping screws from frame cover underneath the snow thrower and move the frame cover away. Refer to Figure 24. • Back out the stop bolt to create sufficient gap between the friction wheel disc and the drive pulley. Pull the drive belt from around the drive pulley and clear it off the friction wheel disc. See Figure 27. Figure 27 • Now moving to the other side of the snow thrower , slide the belt off the crankshaft. • Replace with new belt, first sliding it through the crank shaft, then working it around the groove of the drive pulley and finally wrapping it around the engine pulley from where the old belt was removed. Once the belt is firmly placed on the pulleys, make sure to remove the screwdriver from the idler. • Re-install auger belt on the engine pulley. • Re-attach frame cover and put the equipment back to operating position. Re-attach belt cover with two self-tapping screws removed earlier. Friction Wheel Rubber • Check the rubber on the friction wheel after 25 hours of operation, and periodically thereafter. Replace the 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. • Move shift lever to the R2 position. • Tip the snow thrower so that it rests on the housing. • Remove two self-tapping screws from frame cover underneath the snow thrower and move the frame cover away. See Figure 24. • Remove the right-hand wheel by removing the screw and bell washer which secure it to the axle. • Locate the hex shaft and snap ring on the right side of the snow thrower frame, about two inches from the wheel axle. • Using a suitable tool, carefully remove the outer Ering which secures the hex shaft to the snow thrower frame and lightly tap the shaft’s end to dislodge the ball bearing from the right side of the frame. • Slide the hex shaft downward and to the left while carefully un-meshing the lower gears on the hex shaft from the upper gears on the wheel axle. See Figure 28. • Set the hex shaft’s gears aside. • Carefully remove the inner E-ring from the hex shaft and slide the friction wheel assembly off the hex shaft. NOTE: If you’re replacing the friction wheel assembly as a whole, discard the worn part and slide the new part onto the hex shaft. Follow the steps above in reverse order to reassemble components. If you’re disassembling the friction wheel and replacing only the rubber ring, proceed as follows: • Remove the four screws from the friction wheel assembly and remove the bonded friction wheel. • Reassemble new bonded friction wheel rubber to the friction wheel assembly, turn each screw approximately 2 turns in order shown in Figure 29 until screws are tight. It is important for the rubber to be assembled symmetrically. • Slide the friction wheel assembly back onto the hex shaft and follow the steps above in revers order to reassemble components.
