2 . Center the saddle on the equalizing beam center bushing .
3 . Tighten the
saddle cap fasteners
evenly in 50 foot pounds increments to
250 ± 25 foot pounds torque in the proper sequence to achieve uni-
form bolt tension as shown in Figure 6-14 until the final torque value is
achieved .

The AR2 cross tube connects the two (2) equalizing beams through the equalizing
beam’s center bushings, see Figure 6-15 . The cross tube has clearance to float side-to-side in the
center bushings .
The length of the cross tube will allow side-to-side movement of approximately
1 .9685" (50 mm)
.
For this reason, the cross tube
may appear polished
or have missing paint at each end where it
enters into the center bushings, this is normal .
dO NOT
grease or lubricate the cross tube or the center bushing and
dO NOT
use the cross tube
as a jacking point, see Figure 6-15 .
