Replacement
IMPORTANT:
The trailer MUST be unloaded before
beginning service procedures.
1. With the vehicle unloaded and on a level surface, exhaust
all air from the system and disconnect the air lines from
the PosiLift air springs.
Failure to exhaust the suspension air and
chock the tires prior to beginning
maintenance could allow vehicle
movement which, if not avoided, could
result in death or serious injury.
IMPORTANT:
If air spring has a leak and is deflated,
Step 1 MUST still be performed.
2. Raise lift axle to full up position and support with jack stands.
3. Remove the two (2) 1/2" nuts from the PosiLift air spring
to the hanger mounted lift bracket as well as the two (2)
sets of 3/8" bolts and washers from the beam mounted
lift bracket to the front side of the PosiLift air spring.
4. Install the new PosiLift air spring and air spring mounting
plate to the beam mounted lift bracket and attach with the
two (2) 3/8" bolts and washers
(Figure 21)
.
5. Mount the PosiLift air spring into the hanger mounted
lift bracket and attach with two (2) 1/2" nuts
(Figure 22)
.
Refer to Section 14 for torque requirements.
NOTE:
Air spring should be mounted using the inboard
mounting holes
(Figure 23)
.
6. Reattach the air line to the front of the PosiLift air spring.
7. Check for air leaks by applying soapy water solution and
checking for bubbles at all connections and fittings. If
leaks are found, repair as necessary.
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.
