Ride Height Adjustment
7. Measure distance “B” between the valve arm and mounting
bracket holes to determine linkage length
(Figure 14)
.
8. Adjust the linkage to required length and install the hardware
into the upper and lower connections
(Figure 14)
. Torque
hardware to 30-40 in.-lbs. (3-5 N•m).
NOTE:
It could be necessary to cut linkage rod to
achieve proper length. Be sure to de-burr rod to
prevent link end damage.
9. Raise the trailer approximately 2" (50 mm) above the
ride height and remove the jack stands.
10. Slowly lower the trailer so that the trailer suspension is
fully collapsed.
11. Pull the pin and apply air to the trailer allowing the
suspension to return to ride height.
12. With the suspension at rest, measure the ride height.
Ride height MUST be within 1/4" (6 mm) of the
suspensions specified ride height.
13. Spray a soapy water mix on all air line connections to
check for air leaks and verify fittings are tight.
IMPORTANT:
It is the responsibility of the air system
installer to secure all air lines and check
for air leaks. If air leaks are detected,
repair as required.
Failure to eliminate air leaks could
compromise the suspension performance
which, if not avoided, could result in
component or property damage.
14. Remove the wheel chocks.
