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
Figure
8.Reassemble the new friction wheel onto the hub assembly, tightening the four screws in rotation and with equal force. It is important to assemble the friction wheel symmetrically for proper functioning. Refer to Figure
Figure
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
