1.  Remove pin and washer from transfer rod, and 
remove end of transfer rod from hole in driven disc 
assembly. See Figure 4.9.

spring and slide the driven disc assembly off the 
hex shaft. See Figure 4.12. 
3.  Remove both snap rings that secure rubber 
driven disc hub to thrust plate. See Figure 4.13. 
4.  Slide the rubber driven disc hub out of the 
bearing. 
5.  Drive out existing bearing. 
6.  Install new bearing and secure to thrust plate 
with four retaining screws. Tighten screws securely.
