8.2 Adjustment of Timing Belts
8.2.1 B-Axis
1. Loosen the GT-SA bolts shown in
Reassembly of B- and T-Axis Timing Belts”
2. Adjust the initial tension of the timing belt by pushing the pulley in
the direction in which the timing belt stretches.
3. Temporarily tighten the GT-SA bolts , then adjust the initial tension to
2 "Initial Tension of Timing Belt"
using a tension meter.
4. Tighten the GT-SA bolts with the specified tightening torque. Then,
operate the B-axis at low speed to equalize the tension, and confirm
that the initial tension of the timing belt is the initial tension shown in
2 "Initial Tension of Timing Belt"
.
As the set value of the tension meter, start with the following:
Belt mass:
34 gram per meter (width: 10 mm)
Belt width:
8 mm
Distance between axes: 276 mm
8.2.2 T-Axis
1. Loosen the GT-SA bolts shown in
Reassembly of B- and T-Axis Timing Belts”
2. Adjust the initial tension of the timing belt by pushing the pulley in
the direction in which the timing belt stretches.
3. Temporarily tighten the GT-SA bolts , then adjust the initial tension to

.
As the set value of the tension meter, start with the following:
Belt mass:
34 gram per meter (width: 10 mm)
Belt width:
8 mm
Distance between axes: 184 mm
