Installing the Rack and Pinion
Before You Begin
Before installing the rack and pinion, make sure to remove the handle (79) and lower half band (78) from
factory setting as shown in Figure 3-15, page 27 and re-install the handle (79) back as shown in
Figure 3-16, page 27. The lower half band (78) will be installed when installing the rack and pinion
