15. Pre-Operation
NOTE:
In the United States, workshop safety requirements
are defined by federal and/or state Occupational
Safety and Health Act. Equivalent laws may exist
in other countries. This manual is written based
on the assumption that OSHA or other applicable
employee safety regulations are followed by the
location where work is performed.
1. With the vehicle on a level surface, bring air system to
operating pressure (above 85 psig/5.9 bars).
2. Shut off the vehicle and visually check all air control system
fittings for air leaks by applying a soapy water solution and
checking for bubbles at all air connections and fittings.
Examine the air springs
(Figure 23)
for equal firmness.
3. Check the shock absorbers for proper installation and make
sure that the upper and lower 3/4" shock absorber nuts
are torqued to 140-175 ft.-lbs. (190-237 N•m)
(Figure 23)
.
4. Verify that the 1/2" air spring mounting nuts are torqued
to 30-40 ft.-lbs. (41-54 N•m), and the 3/4" air spring
mounting nuts are torqued to 40-45 ft.-lbs. (54-61 N•m)
(Figure 23)
.
5. With the suspension at full capacity, check that there is a
1" (25 mm) minimum clearance around the air springs.
6. The suspension’s ride height should be within ±1/4" (6 mm)
of the recommended design height. For proper ride height,
refer to Section 12.
7. Determine which pivot bolt style is installed
(Figure 23)
.
If 1-1/8" hex head bolt, verify torque on the nut is
550-600 ft.-lbs. (746-813 N•m).
If 7/8" pan head shear bolt, verify spline has been
sheared off.
IMPORTANT:
The SwingAlign design maintains proper
alignment under correct torque without
welding; DO NOT weld.
NOTE:
SwingAlign pivot connections are on roadside and
fixed alignment pivot connections are on curbside.
For SwingAlign Connection Axle Alignment
procedure, refer to Section 13.
