Leadscrew Assembly
Removal
Refer to Figure 6-13.
1. Remove the cover plate as described in this chapter.
2. Move the Shuttle Assembly about halfway toward the rear.
3. The leadscrew has two flats at the front end. While holding the front of the
leadscrew with a 7/16” open end wrench over the flats, turn the leadscrew retaining
nut clockwise with an 11 mm open end wrench until it has moved about 1/4 inch
from the back surface of the front bearing, assuming that the bearing remains
seated.
4. Observe the rear bearing where it protrudes from the chassis. Grasp the leadscrew
and slide it forward until it disengages from the rear bearing. If the rear bearing
slides forward with the leadscrew, hold the bearing in place by pressing a
screwdriver blade against it outside the chassis.
5. Remove the M3 x10 mm Phillips pan head screw that holds the anti-rotation bracket
in place. Remove the bracket.
6. Disconnect the Shuttle Cable at the Shuttle Assembly.
7. Lift the leadscrew with the Shuttle Assembly in place clear of the chassis. Remove
the washers on each end of the leadscrew and the shim on the front end and store
them in a safe place.
