10.  Slide the hex shaft through the right side of the frame   

toward the left side and through the friction wheel 
assembly.

NOTE: If the sprocket fell from the snow thrower chain while 
removing the hex shaft, position the hex hub of the sprocket 
toward the friction wheel and place the sprocket in the chain.
11. 

After making certain that the chain is on both the large 
and the small sprocket, align the hex shaft with the hex 
hub of the small sprocket, and slide the shaft through the 
sprocket.

12.  Slide the spacer onto the end of the hex shaft.
13.  Align the bearing on the right end of the hex shaft with the 

hole in the right side of the frame, then push the hex shaft 
to the left into position in the frame.

14.  Slide the bearing onto the left end of the hex shaft and 

press into the hole on the left side the frame.

15.  Place the belleville washer (rounded side toward head) 

onto the hex screw removed earlier, and insert the screw 
into the threaded hole of the hex shaft.

16.  Gradually tighten the hex screw to fully seat the bearings in 

each side of the frame and to secure the hex shaft.

17. 

Position the frame cover on the bottom of the frame and 
secure with the self-tapping screws. Pivot the snow thrower 
down to its normal operating position.

Repeat the drive control test from the Assembly 

& Set-Up section of this manual before operating the snow 
thrower.
 

6. 

Lift the friction wheel assembly out between the axle shaft 
and the drive shaft assemblies.

7. 

Remove four screws securing the friction wheel to the hub 
assembly (refer to Figure 7-11). Discard old friction wheel.

8. 

Reassemble the new friction wheel onto the hub assembly, 
tightening the four screws in rotation to 6-9 ft.-lbs. It is 
important to assemble the friction wheel symmetrically for 
proper functioning. Refer to Figure 7-11.

9. 

Reposition the friction wheel assembly in the snow thrower 
frame. Insert the pin from the shift arm assembly into the 
friction wheel assembly and hold assembly in position. 
Refer to Figure 7-12.
