8.2 Adjustment of Timing Belts
Adjustment of Timing Belts
1. Loosen the GT-SA bolts
Reassembly of B- and T-Axis Timing Belts".
2. Adjust the initial tension of the timing belt
the direction in which the timing belt
3. Temporarily tighten the GT-SA bolts , then adjust the initial tension to
the tension specified in Table 8-2 "Initial Tension of Timing Belt" by
using a tension meter.
4. Tighten the GT-SA bolts
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
Table 8-2 "Initial Tension of Timing Belt".
As the set value of the tension meter, start with the following:
Belt mass:
Belt width:
Distance between axes: 276 mm
