3 Installing the Air Locker

 Cover the drive pinion area with a rag to protect it from metal filings.

 Secure the differential housing to the work bench.

 Drill an 11.2mm [7/16”] diameter hole through the differential

housing square to the outside surface.

 Tap the hole from the outside using ¼”NPT thread tap.

 Remove any sharp edges that may chip off from around the hole

and fall into the housing.

 Very carefully, remove the rags and inspect with a service light

inside the housing to insure no metal filings are left behind.

3.4 Final Air Locker Assembly

IMPORTANT:

Some pinion gears extend so far into the differential cavity that

they make contact with the body of the Air Locker.

If this is the case then the end of the pinion gear will have to

be carefully ground or machined away until at least 0.5mm

[0.020”] of clearance exists. This will not adversely effect the

strength of the pinion gear.

Clean all grinding particles from the pinion gear & differential

housing after modifications.

NEVER MODIFY THE AIR LOCKER TO CREATE CLEARANCE.

 Clean all parts of the differential assembly, paying particular

attention to the seal housing journal.

 Place the Air Locker into the differential housing and install the

bearing caps.

NOTE : Be sure to check that the bearing caps are on the

correct sides of the third member and are correctly

aligned.

 Insert the bearing cap bolts and hand tighten.
