Drive Belt
•Follow the first four steps of the instructions for servicing the auger belts.
•Pull idler pulley up, and lift belt off engine pulley and friction wheel disc. See Figure 17.
•Back out the stop bolt until the support bracket rests on the auger pulley. See Figure 19.
•Slip belt between friction wheel and friction wheel disc. See Figure 19. Remove and replace belt.
•Reassemble following the instructions in reverse order.
NOTE: The support bracket must rest on the stop bolt after the new belt has been assembled. See Figure 19.
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.
•Tip the snow thrower up and forward, so that it rests on the housing.
•Remove six
•Remove the click pins which secure the wheels, and remove the wheels from the axle.
•Using a 7/8" wrench to hold the shaft, loosen, but do not completely remove, the hex nut and bell washer on the left end of gear shaft. See Figure 20.

Bell Washer
NOTE: Snow thrower shown resting on its auger housing. Wheels not shown for clarity.

•Lightly tap the hex nut to dislodge the ball bearing from the right side of frame before removing the hex nut and bell washer from left end of shaft.
•Move the gear shaft to the right and slide the friction wheel assembly from the shaft.

•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 21.
•Reassemble new friction wheel rubber to the friction wheel plates and hub, tightening the six screws in rotation and with equal force.
•Position the friction wheel assembly up onto the pin of the shift rod assembly, and slide the shaft through the assembly. Reassemble in reverse order.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary. To remove the skid shoes, proceed as follows:
•Remove the four carriage bolts, bell washers and hex nuts which attach them to the snow thrower.
•Reassemble new skid shoes with the four carriage bolts, bell washers (cupped side goes against skid shoes) and hex nuts. Make certain the skid shoes are adjusted to be level.
To remove shave plate, remove the carriage bolts, belleville washers and hex nuts which attach it to the snow thrower housing. Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely.
Augers
The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. Refer to Figure 14. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear. If the augers will not turn, check to see if the bolts have sheared.
IMPORTANT: NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox or other components as a result of doing so will NOT be covered by your snow throwers warranty.
