8.Remove the bearing plate from the right side. Do not remove the hex shaft. Leave the hex shaft in posi- tion. Carefully raise hex shaft just
enough to allow the friction wheel to be removed.
9.Remove the friction wheel from the hub. Slip the friction wheel toward the right off the hex shaft. See Figure 31.
10.Assemble the new friction wheel onto hub with the fasteners re- moved earlier.
11.Install the bearing plate onto the right side. Make sure the hex shaft is engaged with both bearing plates and that the washers and re- taining ring are installed in the origi- nal position. See Figure 32.
