the feeler gauge to determine a shim amount for ‘D’ in Figure 14.
c 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.
c Remove the Air Locker from the axle housing.
c Install the shim pack ‘D’ between the master shim and the seal
housing as shown in Figure 14.
c Spread the differential housing again (Refer to Section 2.6).
c Re-install the Air Locker assembly into the axle housing without the
original master shim from the right-hand side.
c Rotate the seal housing until the tube is positioned in the center of
the oil drainage notch of the axle housing.
c While holding the Air Locker into the axle housing, lightly tap the
original right-hand master shim into place on the right-hand side
between the Air Locker master shim and the bearing seat of the
axle assembly. (Refer to Figure 16.)
