8.4 Adjustment of Timing Belts
 L-axis
Refer to Fig. 8-1 “Disassembly & Reassembly of L- and U-Axis Timing
Belts”. Loosen the GT-SA bolts and adjust the initial tension to be the
specific initial tension as shown in Table 8-4 “Initial Tension of Timing Belt”
with the tension meter. Then tighten them with the specified tightening
torque.
 U-axis
Refer to Fig. 8-1. Loosen the GT-SA bolts and adjust the initial tension
to be the specific initial tension as shown in Table 8-4 with the tension
meter. Then tighten them with the specified tightening torque.
 R-axis
Refer to Fig. 8-2 “Disassembly & Reassembly of R-Axis Timing Belt”.
Loosen the GT-SA bolts and adjust the initial tension to be the specific
initial tension as shown in Table 8-4 with the tension meter. Then tighten
them with the specified tightening torque.
 B-axis
Refer to Fig. 8-3 “Disassembly & Reassembly of B- and T-Axis Timing
Belts”. Loosen the GT-SA bolts and adjust the initial tension to be the
specific initial tension as shown in Table 8-4 with the tension meter.
Then tighten them with the specified tightening torque.
 T-axis
Refer to Fig. 8-3. Loosen the GT-SA bolts and adjust the initial tension
to be the specific initial tension as shown in Table 8-4 with the tension
meter. Then tighten them with the specified tightening torque.
