3 Installing the Air Locker

3.9.1

Re-Shimming the Backlash

NOTE : This step is only necessary when adjusting for

incorrect backlash.

 Remove the bearing caps.

 Remove the differential as before.

NOTE : Never spread the housing on the aluminum models.

 To decrease the amount of backlash, reduce the shim thickness ‘B’

(Fig.7.) and increase the shim thickness ‘D’ (Fig.9.) by the same

amount. Reverse this step to increase the backlash.

 Remount the differential as before.

 Release spreader tension (if applicable).

 Check backlash again as before.

3.10

Setting Up the Bulkhead Fitting

 Apply thread sealant to the threads of the bulkhead body.

 Screw the bulkhead body into the tapped hole, and tighten.

 Wipe the area clean of any excess thread sealant (inside and

outside of the housing).

 Insert the free end of the seal housing tube into the bulkhead fitting

until it protrudes approximately 8mm [5/16”] through the other side.

 From the outside of the housing, assemble the small O-ring over

the top of the short length of seal housing protruding through the

bulkhead fitting.

 While still holding the seal housing tube into the bulkhead fitting,

insert the small drilled end of the center compression nut over the

extended tube as shown in the assembly diagram (Fig.15.), and

screw it into the bulkhead body, and lightly tighten.

NOTE : Be sure to insert the correct end of the center

compression nut into the bulkhead body. The thread

has been partially relieved on the bulkhead side of the

center compression nut to visually identify its

orientation. (Fig.15.)
