8.2 U Axis Backlash Check
1. Use a dial gage to check the backlash of the large gear as shown in the photo below.
When checking the backlash the small gear should be held so it does not move. The
backlash should be in the range 0.08mm to 0.15mm. If the backlash is not in the range
loosen the installation bolts for the large gear and adjust as required.

1. When measuring the U axis belt tension it is necessary to put the shuttle against the
minus mechanical stopper.
2. Refer to the following illustrations and check that the tension of each belt is within the
correct range:
T axis measuring point
U axis measuring point
Belt unit weight Belt width Belt span Frequency range
T axis
2.5gf/mm 15mm 151mm 147 +/- 7 Hz
U axis
0.25gf/mm 9mm 566mm 37 ~ 41 Hz
