Removal and Replacement 6-35
Reassembly of the X-axis Motor and Drive
Assembly
For reassembly, apply a small amount of grease on the tip of the nose
cone. Apply a small amount, 3 dabs, on the threads of the X-axis
shaft. Be sure to rotate the black, plastic retainer so it ends locks the
yoke in position. Perform the procedure “ X-axis scale adjustment.”
CAUTION
When reinstalling the motor, take care to fully seat the motor
positioning boss into the stiffener panel for proper operation.
1. Place the retainer over the leadscrew. Orient it so that the flat
side faces generally toward the motor.
2. Put lubrication on the leadscrew and screw the threaded
gear—longer hub facing out. Turn it all the way on (clamped
against the stop collar) then back off 1/4 turn.
NOTE: The X-axis shaft/head assembly will be spring loaded but
should otherwise be free to travel.
