8 Disassembly and Reassembly and Adjustment of Timing Belts
8.1 Disassembly and Reassembly of L- and U-Axis Timing
Belts
• Refer to Fig. 8-1 “Disassembly & Reassembly of L- and U-Axis
Timing Belts”.
 Disassembly
1. Turn OFF the DX100/DX200/FS100 power supply.
2. Unscrew the hexagon socket button head screws and remove the
cover .
3. Unscrew the GT-SA bolts and remove the L-axis timing belt .
However, without the L-axis timing belt , its posture cannot be kept.
So when remove the L-axis timing belt, support the L-arm to avoid it
from rotating.
4. Unscrew the GT-SA bolts and remove the U-axis timing belt .
However, without the U-axis timing belt
, its posture cannot be kept
as the L-axis. So when remove the U-axis timing belt, support the U-
arm to avoid it from rotating.
 Reassembly
1. Mount the L-axis timing belt and the U-axis timing belt .
2. Adjust the initial tension of the timing belt. (Refer to section 8.4
“Adjustment of Timing Belts”.) Then tighten the GT-SA bolts with
the tightening torque shown in Table 8-1 “L- and U-Axis Timing Belts
Parts Checklist”.
3. Mount the cover and tighten the hexagon socket button head
screws with the tightening torque shown in Table 8-1.
4. Turn ON the DX100/DX200/FS100 power supply.
NOTE
Refer to Chapter 3 “Home Position Return” and Chapter 5
“Disassembly and Reassembly of the Motor”.
