10.9.Holding the friction wheel assembly, slide the hex gear shaft to the right. See Figure 22.
If you're disassembling the friction wheel and replacing only the rubber ring, proceed as follows:
10.13.Remove the four screws that secure the friction wheel's side plates together. See Figure 24.

NOTE: It may be necessary to use a drift punch on the left side of the shaft to drive it from the bearing.
10.10.Lift the chain off the small sprocket.
10.11.Catch the bearing, sprocket and friction wheel as they come off the shaft. See Figure 23.
Hex Shaft

NOTE: Maintain the correct order of parts during disassembly.
10.12.Inspect the friction wheel for wear or damage.
NOTE: The friction wheel can be replaced as an assembly or repaired.
If you're replacing the friction wheel assembly as a whole, discard the worn assembly and slide the new assembly onto the hex shaft. Follow the steps above in reverse order to reassemble components.
Figure 24
10.14.Remove the rubber ring from between the plates.
10.15.Reassemble the side plates with a replacement rubber ring.
IMPORTANT: Tighten each screw only one rota- tion before turning the wheel clockwise and pro- ceeding with the next screw. Repeat this process several times to ensure the plates are secured with equal force.
10.16.Slide the friction wheel assembly back onto the hex shaft and follow the steps above in reverse order to reassemble components.
11.PLANETARY GEAR REMOVAL
NOTE: It is not necessary to remove any belts to service the planetary gears.
11.1.Remove the wheels on the side of the unit you will be servicing.
