LEAK TEST
1. Remove assembly intact.
2. Connect test gage to regulator. Inflate reservoir
through service valve to 80-1 10 psi.
3. Route an 8" piece of rubber hose between vacuum and
vent ports (Fig. 3D-32).
4. While holding assembly in a vertical position with
reservoir end down, immerse in water until diaphragm is just
submerged. Observe for air leaks at:
CAUTION: Do not submerge completely, as
water can enter around the cover gasket.
0

caused by atmospheric air being purged from air pockets in
the second stage housing. If the bubbles stop, there is no leak.

5. Remove hose from vacuum port and submerge
disconnected end in water. Cover vacuum port with finger.
D o not permit water to enter through vacuum port. If bubbles
are evident, the probable cause is a defective second stage
housing check valve.
6. Correct any leaks by either tightening screws or
replacing parts.
7. If the cover gasket area is inadvertently submerged,
remove cover and tilt unit so that water may drain through
openings by distributor valve mechanism. Move distributor
valve from side to side until all water is purged. Blow dry with
compressed air, both the distributor valve mechanism and
interior of the cover. Replace cover.
NOTE: If the compressor passes this test, yet fails the
output test, the compressor, reservoir and regulator
needs to be overhauled.
HEIGHT CONTROL VALVE TEST--OFF
CAR
I . Remove control valve from car.
2. Clean exterior of control valve thoroughly.
3. Connect test gage and air pressure source to intake
adapter and open air pressure (80-1 10 psi).
4. Submerge unit in water. No air should escape if
overtravel lever is in neutral position. If bubbles escape from
Superlift port, replace control valve.
5. Shut off air pressure and detach test gage from air
intake port. Plug intake port with fill valve from J 22695
adapter package.
