will be necessary to obtain Test Gage J 5907 with
adaptor package J 22695 or equivalent. A test gage can
be made up by collecting and assembling the following
parts:
PARTS REQUIRED
1. Fill valve.
2. A tee, which has three 1/8" female taper pipe
threads.
3. One 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.
4. Air Pressure Gage J 5907.
5. One male connector, which has a 1/8" male taper
pipe thread on one end and a 3/8"-24 straight thread
male thread on the other end.
6. Two metal sleeves, rubber seals and tube nuts.
7. A length of 1/8" tubing.
ASSEMBLE
1:Install adapter in tee.
2. Install connector in one end of tee.
3. Install fill valve in other end of tee.
4.
Install Pressure Gage J

in adapter.
5. Install fitting nut on tubing, then install metal sleeve
and rubber seal over end of tubing until tubing
bottoms in rubber seal. Tubing, nut and seal assembly
can now be installed on connector opposite the fill
valve. Tighten fitting nut to 70 lb. in. torque.
NOTE:

COMPRESSOR OUTPUT TEST--ON CAR
1. With all engine operated accessories turned off and
ignition turned off, deflate system through service
valve. Remove high pressure line at regulator and
connect test gage (Fig. 4-25).
2. Inflate reservoir to
70
psi through service valve.
3. Observe test gage for evidence of compressor air
leak.
4. If leaking, proceed to leak test the compressor,
reservoir and regulator as outlined below. If not
leaking, continue with this test.
5. With engine running at slow idle, observe reservoir
build-up for five minutes. Reservoir pressure should
build up to a minimum of 90 psi.
6. If compressor fails to cycle, make sure the vacuum
line and filter is open and unobstructed before
removing compressor for repair.
7. If build-up is too slow, proceed to repair compressor
as outlined in Servicg Procedures.
8. Satisfactory build-up indicates system problem to be
in the control section. However, again observe the test
gage for evidence of an air leak and proceed
accordingly.
PRESSURE REGULATOR TEST
Performance test the regulator with a known good
compressor on the car.
1. Deflate system through service valve and disconnect
line at pressure regulator valve. Install test gage on
regulator valve Egh pressure fitting (Fig.
4-25).
2. Inflate system througt service valve to maximum
available pressure (Fig. 4-24).
