3 Installing the Air Locker
24
PRE-LOAD + END FLOAT = SHIM PACK
Create a shim pack
‘D’
from the shims supplied with your
Air
Locker
.
NOTE : Do not add shims between the bearing cone and the
bearing seat and
NEVER machine the Air Locker.
Remove the
Air Locker
from the axle housing.
Install the shim pack
‘D’
between the ARB master shim and the
seal housing as shown in Figure 13.
Spread the differential housing again (Refer to Section 2.6).
Re-install the
Air Locker
into the axle housing.
NOTE : If the Air Locker is too tight to fully install then the
spreader tension may need to be increased. Do not
spread the housing more than 0.50mm [0.020”].
Rotate the seal housing until the tube is positioned in the center of
the oil drainage notch of the axle housing. (Fig.19.)
Figure 19.
Release all spreader tension.
Check that some backlash can be felt between the ring and pinion
gears. No backlash would be an early indication of incorrect shim
thickness.
