Beam Mounted LIft Bracket Replacement
11. Beam Mounted Lift Bracket
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.
2. Support the suspension beams with jack stands to
prevent the equalizing beam pivot from moving.
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.
3. Remove the two (2) 3/8" bolts and washers from the beam
mounted lift bracket to the PosiLift air spring.
4. Remove the two (2) 1/2" bolts, washers and nuts from
the beam mounted lift bracket to the cast beam.
5. Install the new beam mounted lift bracket by placing the
lift bracket under the cast beam and installing the two (2)
sets of 1/2" bolts, washers and nuts
(Figure 18)
.
Refer to Section 14 for torque requirements.
6. Install PosiLift air spring into the beam mounted lift
bracket using the two (2) 3/8" bolt and washers to the
inboard mounting holes on the bracket
(Figure 19)
.
Refer to Section 14 for torque requirements.
NOTE:
Air spring should be mounted using the inboard
mounting holes
(Figure 20).
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.
8. Remove the jack stands.
NOTE:
It is recommended to re-align the trailer axle
after the pivot connection is taken apart. Refer to
Section 8 for alignment procedures.
