GENERAL DESCRIPTION

A pneumatic level control system that automatically

maintains correct rear trim height of a car under varying

load conditions, the optional automatic level control is

used only in conjunction with the Superlift Shock Absorber

option.

The Superlift Shock Absorber option alone, consists of

the two shock absorbers with pressure lines to a "Tee"

where a ill valve is located, the shocks are inflated

with (or deflated of) compressed air (at any gas station)

to obtain the vehicle level desired with any given load

change.

The automatic leveling system is added to the Superlift

Shock Absorbers and supplies its own compressed air.

The system (fig. 13) consists of a vacuum operated air

compressor with pressure regulator,
and
integral storage

tank, vacuum line to engine, air intake filter, air lines,

and a height control valve.

The COMPRESSOR is a two-stage, vacuum actuated

type, requiring no lubrication. Vacuum supply is taken

from engine carburetor base. High pressure air is
supplied to the reservoir tank by the second stage of

the two-stage compressor. The first stage intake stroke

draws air at atmospheric pressure through a oneway

check valve located in the end of the first stage housing

under the first ^tagei housing cover. On the first stage

compression stroke, the intake valve is closed and the

oneway check valve in the second stage end of the piston

is opened. This allows the air from the first stage

cylinder to flow through the hollow piston into the second

stage cylinder for jhigh pressure compression. The

second stage compression stroke closes the check valve

in the piston and opeijis the check valve in the end of the

second stage housing.

The intake and compression strokes are controlled by a

sliding distributor valive that is actuated through an arm

that is tripped by the piston as it nears the end of each

stroke. Each time the arm actuates the distributor

valve, a different set of holes are covered in the first

stage housing. The distributor valve controls the flow of

intake manifold vacuum and air under atmospheric pres-

sure,
alternatley to opposite sides of the compressor

diaphragm.

As the compressor cycles, the reservoir air pressure

gradually increases causing a back pressure on the sec-

ond stage piston until it equals the push of pressure

against the diaphragm- At this point, a balanced condi-

tion is reached and the unit stops operating. After res-

ervoir pressure drops due to system air usage, the com-

pressor again begins to cycle and replenish the

reservoir.

Pressure balance will depend upon the prevailing mani-

fold vacuum and atmospheric pressure. Both are af-

fected by altitude above or below sea level. Balance

pressure will vary from approximately 150 to 275 psi.

NOTE: After completion of work on this sys-

tem or when servicing other parts of the car and

the system is deflated, inflate the reservoir to

140 psi or maximum pressure available through

the compressor service valve.

The PRESSURE REGULATOR VALVE is preset and

limits the reservoir outlet pressure to approximately 125

psi to avoid damage to the height control valve and Super-

lift shocks.

The HEIGHT CONTROL VALVE, which is mounted on

the frame, senses rear car height through a link attached

to the right rear upper control arm. When load is added

to the car, the overtravel lever is forced up causing an

internal lever to open the intake valve, when this valve

is open high pressure air is admitted to the Superlift

shocks. As the car raises to level, the intake valve shuts

off.

When load is removed from the car, the overtravel

lever is forced down causing the internal arm to open the

exhaust valve. As the car lowers to the level position,

the exhaust valve shuts off.

A four to eighteen second time delay mechanism, which

is built into the height control valve, prevents air trans-

fer due to normal ride movements. The overtravel

lever, which pivots around the control valve shaft, rides

off the flat side of the control valve shaft and does not

have time to. react to the rapid changes or normal ride

motions.
During changes due to loading, the time delay mecha-

nism will allow the overtravel shaft to open either the in-

take or exhaust' valve as required, since this is not a

rapid movement.

The SUPERLIFT shock absorber is essentially a con-

ventional hydraulic unit with a. pliable nylon reinforced

neoprene boot acting as an air chamber.

The unit will extend when inflated and retract when de-

flated by the control valve.

An eight to fifteen psi air pressure is maintained in the

Superlift at all times to minimize boot friction- This is

accomplished by a check valve in the exhaust fitting on

the control valve. Neither shock absorber function nor

conventional ride motions thru rear coil springs is im-

paired in the event of accidental air pressure loss. .

A combination of steel tubing and reinforced rubber

hose is used for air lines throughout the system.

Deflate system through service valve and disconnect

line at pressure regulator valve. Install test gauge on

regulator valve high pressure fitting.

Inflate system through service valve to maximum

available pressure.

NOTE: If available pressure is less than 140

psi,
start engine to build-up reservoir to this

pressure.

Regulated pressure should build-up to and hold

steady at 100-130 psi on test gauge.

Check regulated pressure by momentarily (not more

than one second) depressing valve core on test gauge

arid observe gauge reading.

If regulated pressure now reads less than 100 psi,

replace regulator assembly.

If regulated pressure exceeds 130 psi, replace regu-

lator assembly.

Control Valve Test

Exhaust (Superlifts Inflated)

1.
Disconnect control valve lever from link.

2.
Hold lever down in exhaust position until Superlifts

deflate or for a minimum of 18 seconds.

3.
If Superlifts deflate, perform Intake Check.

4.
If Superlifts do not deflate, remove exhaust adapter

from control valve and hold lever down as in Step 2.

Replace adapter, O-ring and filter if this deflates

Superlifts.

5.
Replace control valve if none of the above steps solve

problem.

Intake (Reservoir Pressure 125 psi Minimum)

1.
Disconnect overtravel lever from link.

2.
Hold lever up in intake position until Superlifts in-

flate or for a minimum of fifteen seconds.

3.
If Superlifts inflate and hold, proceed to Time Delay

Check. '•

4.
If Superlifts inflate and then leak down, perform leak

test on lines and fittings and then on Superlifts and

control valve. Repair or replace as indicated.

Time Delay Test (Reservoir Pressure 125 psi Minimum)

1.
Record rear trim height of empty car (rear bumper

to ground).

2.
Add weight equivalent to two passenger load to rear

of car. Car should begin to level in 4-18 seconds.

3.
Remove weight. After 4-18 seconds car should begin

to settle.

4.
Replace valve if time delay is not within the 4-18

seconds.

Trim Adjustment—On Car

Trim adjustment should be performed with a full fuel

tank (or the equivalent in load at the rate of 6 lbs
./gal-

lon)
,
but no other load.

Abbreviated Adjustment

1.
Fill the compressor at the service valve with the

available air line pressure.

2.
Disconnect link from height control valve lever.

Move the height control valve lever upward until air

fills the Superlifts.

3.
Move lever downward and hold until air stops escap-

ing from the exhaust port of the height control valve.

The Superlifts will now automatically hold 8 to 15

PSI.
;

4.
Let lever go to its neutral position> and loosen the

lever adjustment nut.

5.
Assemble the link to the height control valve lever

and tighten the lever adjustment nut.

NOTE: Do not move control valve lever and

overtravel body while tightening nut.

Leak Tests

Compressor, Reservoir and Regulator

1.
Remove assembly intact.

2.
Connect test gauge to regulator. Inflate reservoir

through service valve to 80-110 psi.

3.
Route an 8" rubber hose between vacuum and vent

ports,
(fig. 16).

4.
Submerge in water and observe for air leaks at:

Reservoir weld seam.

Reservoir to compressor O-ring.

Regulator to compressor O-ring.

Regulator boot-defective internal.O-rihg.

Diaphragm between first and second stage housings.

' Tightening through bolts may correct the leak.

Cover gasket and retainer screw. A few bubbles here

is not a leak. A continuous stream indicates defec-

tive compressor check valves.

Service valve.

Test gauge connections.

5.
Correct any leaks detected by either tightening

screws or replacing parts.
