Troy-Bilt 772C0772 warranty Maintaining Your Snow Thrower, Friction Wheel Removal

1	Friction Wheel Removal
	If the snow thrower fails to drive with the drive control
	engaged, and performing the drive control cable adjust-
	ment on page 12 fails to correct the problem, the friction
	wheel may need to be replaced. Follow the instructions
	below. Examine the friction wheel for signs of wear or
	cracking and replace if necessary.
	•	Place the shift lever in third Forward (F3) position.
	•	Drain the gasoline from the snow thrower, or place a
		piece of plastic under the gas cap.
	•	Carefully pivot the snow thrower up and forward so
		that it rests on the auger housing.
	1.	a. Remove the frame cover from the underside of
		the snow thrower by removing four self-tapping
		screws which secure it.
		b. Remove the right-hand wheel by removing the
		screw and cupped washer which secure it to the
		axle.
	2.	Carefully remove the hex nut and washer which
		secures the hex shaft to the snow thrower frame and
		lightly tap the shaft’s end to dislodge the ball bearing
2		from the right side of the frame.
	3.	Carefully position the hex shaft downward and to
		the left before carefully sliding the friction wheel
		assembly off the 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 disassem-
	bling the friction wheel and replacing only the rubber
	ring, proceed as follows:
	4.	Remove the four screws which secure the friction
		wheel’s side plates together.
	•	Remove the rubber ring from between the plates.
	•	Reassemble the side plates with a new rubber ring.
	•	Slide the friction wheel assembly back onto the hex
		shaft and follow the steps above in reverse order to
		reassemble components.

Maintaining

Your Snow

Thrower

When reassembling the friction wheel as- sembly, tighten each screw only one rota- tion before turning the wheel clockwise and proceeding with the next screw. Repeat this process several times to ensure the plates are secured with equal force.

NEVER replace the auger shear pins with standard hex pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.
