IMPORTANT
After you correctly tighten the locknut that secures the castor fork
to the carrier frame, it should take 7.3 to 8.5 N∙m (65 to 75 in-lb) to
rotate the castor fork.
6. Install the locknut onto the castor fork and tighten the locknut until the castor
fork requires 7.3 to 8.5 N∙m (65 to 75 in-lb) to rotate.
7. Remove the plug (item 8 in Figure 196) from the carrier frame. Use the
grease gun through the plug hole in the frame, fill the area surrounding the
castor fork shaft with grease. Allow grease to fill the cavities below the lower
bearing, between the bearings, and above the upper bearing. Install the plug
again into the frame.
