Replacement
Refer to Figure 6-13.
1. Place the leadscrew with the Shuttle Assembly inside the chassis. The pulley end
goes toward the rear. Place the washers that were removed during disassembly on
each end of the leadscrew, and the shim on the front end. The washer should be
behind the shim.
2. Insert the front of the leadscrew into the front bearing.
3. Place the leadscrew pulley inside the belt and position the back end of the leadscrew
adjacent to the rear bearing. Move the leadscrew to the rear until the end of the
leadscrew is inside the rear bearing as far as it will go.
4. While holding the front of the leadscrew with a 7/16" open end wrench over the
flats, turn the leadscrew retaining nut counter-clockwise with an 11 mm open end
wrench until it is near, but not touching, the back surface of the front bearing.
5. Verify that there is end play in the leadscrew. Turn the leadscrew retaining nut
counter-clockwise one-quarter turn. Check for end play again. If there is end play,
tighten the nut another one-quarter turn. Continue to tighten the nut one-quarter turn
at a time until the end play just disappears, but no further. Do not overtighten.
6. Install the anti-rotation bracket and its spacer onto the Shuttle Assembly using an
M3 x 8 mm Phillips pan head screw.
7. Apply pressure near the bottom of the shuttle to move the shuttle forward and
backward. Make sure the leadscrew operates smoothly.
8. Connect the Shuttle Cable at the Shuttle Assembly.
9. Apply power to the module and make sure that the Shuttle Assembly is operating
correctly.
10. Replace the cover plate as described in this chapter.
