MAINTENANCE
Machine Alignment
Floating Alignment Cable Tension Adjustment
1. The alignment tube must be able to move up and
down freely while adjusting cable tension.
If necessary loosen the cap screw until the align-
ment tube moves up and down freely. See Figure
87-1.
2. Measure the distance from the end of the align-
ment tube down to the pipe. This is the pre-weight
measurement. See Figure 87-2.
3. Place a 13 lb (5.9 kg) weight on the alignment
tube. Center the weight over the cable attach-
ment assembly. See Figure 87-3.
A standard 7/8 in (22.2 mm) square driveshaft
60 in (1524 mm) long weighs approximately 13
lb (5.9 kg).
4. Measure the distance from the end of the align-
ment tube to the span. This is the weighted mea-
surement. See Figure 87-3.
Subtract the weighted measurement from the
pre-weight measurement. The remaining dimen-
sion is the amount of cable deflection. The cable
deflection should be 1-1/4 in (32 mm).
5. Adjust the hook bolts evenly to obtain the proper
cable deflection. See Figure 87-3.
To insure equal tension in the cables, make sure
the alignment tubes attached to the cables are
aligned with the span.
