4. Carefully pivot the snow thrower up and forward so that it rests on
the auger housing.

by removing four self-tapping screws which secure it. Refer to
Figure 23.
6. Slip the drive belt off the pulley and between friction wheel and
friction wheel disc. See Figure 27.
7. Remove and replace belt in the reverse order.
NOTE: Engaging the drive control will ease reassembly of the belt.
FRiCtion Wheel Removal
If the snow thrower fails to drive with the drive control engaged, and
performing the Drive Control Cable Adjustment fails to correct the
problem, the friction wheel may need to be replaced. Examine the
friction wheel for signs of wear or cracking and replace if necessary.
NOTE: Several components must be removed and special tools are
required in order to replace this snow thrower’s friction wheel rubber.
Contact the nearest Sears Parts & Repair Center as instructed onpage
2 if your friction wheel rubber needs to be replaced.
