Bench Testing the Air Locker
To test the
Air Locker
, when 620kPa [90 PSI] shop air is applied to
the seal housing tube, the
Air Locker
should engage.
Check all fittings and the seal housing for air leaks.
Rotate the differential carrier by turning the pinion flange whilst
applying air pressure.
NOTE : An accurate way to test for air leaks is to fit a shut-off
valve to an air pressure gauge (Available as ARB part
#0770005). Charge with shop air until 620 KPA [90 PSI]
is reached, shut the valve off, disconnect the air hose,
and watch to see if there is any drop in pressure. Any
gradual pressure drop indicates an air leak. (Fig. 16.)
Figure 16.
If a leak is found to be present, spray a soap and water mixture
onto the bulkhead air fitting. Bubbles should appear at any leak
points.
NOTE : Do not spray this soapy mixture inside the differential
.
Check that leaky fittings have been adequately tightened.
Disassemble, clean threads, and reapply thread sealant if leaking
persists.
If a leak is found at the seal housing, carefully remove and refit. Be
very careful with the O-rings and check they have not been
damaged during installation.
