5.3 Disassembly and Reassembly of the U-Axis Motor
• Refer to Fig. 5-3 “Disassembly & Assembly of U-Axis Motor”.
Disassembly
1. Turn OFF the DX100/DX200/FS100 power supply.
2. Unscrew the hexagon socket button head screws and remove the
covers on the right and left sides
3. Connect the backup battery with the cable of U-axis motor .
(Refer to Chapter 2 “Notes for Maintenance”.)
4. Disconnect the cables (both encoder and power-cables) of the U-axis
motor from the internal wiring harness.
5. Unscrew the hexagon socket head cap screws and remove

U-arm to avoid it from rotating.
6. Unscrew the GT-SA bolts and remove the M-base
from the U-
axis motor .
7. Unscrew the hexagon socket head cap screw and remove the
pulley .
Reassembly
1. Mount the pulley on the U-axis motor .
2. Attach the conical spring washer and the washer to the hexagon
socket head cap screw , then apply LOCTITE 242 to the thread part
and tighten it with the tightening torque shown in Table 5-3 “U-Axis
Motor Parts Checklist”.
3. Mount the M-base on the U-axis motor and tighten the GT-SA
bolts with the tightening torque shown in Table 5-3.
4. Mount the U-axis motor which is reassembled to the step 3 on the
U-arm and put the timing belt on the pulley .
5. Attach the conical spring washer to the hexagon socket head cap
screws , tighten them with the tightening torque shown in Table 5-3.
(Refer to section 8.1 “Disassembly and Reassembly of L- and U-Axis
Timing Belts” and adjust the initial tension of the timing belt.)
6. Connect the cables (both encoder and power-cables) of the U-axis
motor with the internal wiring harness.
7. Remove the backup battery.
8. Mount the cover and
