Drive Belt, Changing the Friction Wheel Rubber

DRIVE BELT

1.Follow steps 1 through 4 of previous instructions.

2.Pull idler pulley up, and lift belt off engine pulley and friction wheel disc. See Figure 26.

3.Using a 7/16" wrench, loosen the nut on the stop bolt until the support bracket rests on the auger pulley. See Figure 28.

4.Slip belt between friction wheel and friction wheel disc. See Figure 28. 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 28.

3.	Remove six self-tapping screws from the frame
	cover underneath the snow thrower.
4.	Remove the klick pins which secure the wheels,
	and remove the wheels from the axle.
5.	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 29.
6.	Lightly tap the hex nut to dislodge the ball
	bearing from the right side of the frame.
	Remove the hex nut and bell washer from the
	left end of shaft.
7.	Slide the gear shaft to the right, then slide the
	friction wheel assembly from the shaft.
8.	Remove the six screws from the friction wheel
	assembly (three from each side). Remove

	the friction wheel rubber from between the
	friction wheel plate.
9.	Reassemble new friction wheel rubber to the
	friction wheel assembly, tightening the six
	screws in rotation and with equal force.
10.	Slide friction wheel assembly back onto the
	gear shaft. Be sure to align the pin on the shift
	rod with the hole in the friction wheel assembly.
	See Figure 27. Reassemble in reverse order.

CHANGING THE 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.

1.Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.

2.Tip the snow thrower up and forward, so that it rests on the housing.
