CONNECTORS
Fig.
15 - Test Gauge Set J-22124
NOTE: To service the Automatic Level Con-
trol it will be necessary to secure Gauge Set
J-22124 or make up the following test gauge. If
the connectors indicated are not readily avail-
able others may be substituted.
1.
Collect the following parts:
a. Fill Valve, J-21999.
b.
A tee which has three 1/8M female taper pipe
threads.
c. An adapter which has a 1/4" female taper pipe
thread on one end and a 1/8" male taper pipe
thread on the other end.
d. Air Pressure Gauge, J-4872.
e. Two metal sleeves, rubber seals and tube nuts.
f. A length of 1/8" tubing. ~
g. Two male connectors which have a 1/8" male
taper pipe thread on one end and a 3/8-24 straight
thread male fitting on the other end.
2.
Assembly
a. Connect Fill Valve, J-21999, (female end) at male
connector 3/8-24 straight thread fitting.
b.
Connect other end of male connector to tee.
c. Connect adapter to tee.
d. Connect pressure regulator to adapter.
e. Connect second male connector to tee, (1/8 inch
male pipe thread fitting).
f. Install tubing to connector; other end of tubing
will go on unit to be checked.
NOTE:
Make certain all fittings are air tight.
Compressor Output Test—On Car
1.
With all accessories off, run the engine until fast idle
screw is off the fast idle cam. Turn off ignition.
2.
Deflate system through service valve, then remove
high pressure line at regulator adapter and connect
test gauge.
3.
Inflate reservoir to 70 psi through service valve.
4.
Observe test gauge for evidence of compressor air
leak.
5.
If leaking, proceed to leak test-compressor reser-
voir, and regulator. If not leaking, continue this
test.
6. With engine running at slow idle, observe reservoir
build-up for five minutes. Reservoir pressure should
build up to a minimum of 90 psi.
7.
If compressor fails to cycle, make sure the vacuum
and air intake lines are open and unobstructed before
removing compressor for repair.
8. If build-up is too slow, proceed to repair com-
pressor.
9. Satisfactory build-up indicates system problem to be
in the control section. However, again observe the
test gauge for evidence of an air leak and proceed
accordingly.
Regulator Test and Adjustment
Performance test the regulator with a known good com-
pressor on the car. *
