3 Installing the Air Locker

3.9

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, once 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, if so,

this will indicate 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.
