8.Rotate the adjustment plate in small incre- ments, then test the backlash.

Note: To test the backlash, re-install the key and ball handle onto the leadscrew.

9.When you are satisfied with the amount of backlash, re-tighten the adjustment plate cap screws.

10.Make sure that all mating surfaces are clean from debris and oil, then re-install the bearing housing, key, graduated dial assembly, and ball handle.

Note: When re-installing the bearing hous- ing, make sure the way cover mounting flanges (see Figure 66) are on the top for proper alignment.

If the bearing housing does not easily slip onto the alignment pins, use light taps from a dead-blow hammer or wooden mallet evenly on all sides of the housing to gradually seat it against the saddle.

The longitudinal leadscrew backlash is adjusted in the same manner as the cross feed. Refer to Figure 68 for the location of the longitudinal back- lash adjustment plate and cap screws.
