CAUSE
CORRECTION
Broken or cracked line.
Loose connections or leaking valve core.
Fill valve leaking.
Superlifts leaking.
a. Inflate system to approximately 90 psi
and inspect lines for evidence of escaping
air. If lines are leaking, repair as needed.
b. Apply a solution of soap and water to all
connections and valve core. If air bubbles
appear, repair leak.
c. Detach valve assembly from car with air
pressure retained inside valve and immerse
assembly in water. If air bubbles appear,
repair leak.
d. Remove Superlifts from car and immerse in
water with air pressure applied to Superlift.
If air bubbles appear, Superlift is leaking
and should be replaced.
SUPERLIFTS NOISY WHEN CAR
CAUSE
CORRECTION
a. Loose upper or lower mounting.
a. Inspect and tighten all connections.
b. Rubber mounting bushings worn or cracked.
b. Replace bushings if defective.
c. Internal failure of Superlift.
c. Road test car after above steps have been
performed. If noise is still present, replac
Superlifts.
GENERAL DESCRIPTION
The Superlift system is an assist-type leveling device
which the owner controls manually by varying air pressure
in the system. The leveling unit is a combination of a pliable
neoprene boot and air cylinder built around a hydraulic shock
absorber (Fig. 3D-19). As an integral part of the rear
suspension, it offers the car owner added load-carrying
flexibility. A level ride can be maintained when carrying
abnormal loads by merely increasing air pressure in the
system. When load is removed, the car can be lowered to its
normal riding height by decreasing air pressure. Air pressure
is adjusted by means of a tire-type valve conveniently located
in the rear bumper area. Since one valve serves both units,
air pressure is equal at all times. Superlifts are available on
A, B and G Series.
LEVELING UNIT
The Superlift leveling unit is mounted in the same
location as a conventional rear shock absorber. The units are
designed so that shock absorber function is not impaired in
the event of accidental air loss.
A fitting at the rear bumper contains a tire-type valve
which provides a means of filling of shocks with air and
exhausting air from the shocks.
LINES A N D FITTINGS
A 1/8" diameter flexible air line is used to allow for
relative motion of shock absorbers with rear suspension
movement. Connections to the Superlift leveling units and fill
valve are made with compression fittings (Fig. 3D-20). Each
fitting consists of a rubber seal, metal sleeve and nut. These
parts are intended specifically for the 1/8" diameter line and
must be used to affect a reliable seal.
NOTE: While the lines (Fig. 3D-21) are flexible for easy
routing and handling, care should be taken not to kink
them and to keep them from coming in contact with the
exhaust system.
PRECAUTIONS
To insure satisfactory functioning of the Superlift
system, observe the following precautions:
0
Maintain a minimum of 10 psi for best ride
characteristics with an empty car.
0
Vary pressure up to a maximum of 90 psi to level the
car with loads.
