4 Installing the Air Locker

c Set a depth indicator on one of the ring gear teeth as in figure 12.

c While supporting the pinion gear by holding the drive shaft, rotate

the differential in both directions while observing the maximum

variation in depth from the indicator (i.e., the highest value minus

the lowest value).

c Make sure backlash is less than 0.5mm.

NOTE : This backlash value is for the tube position only and

will not be used for final assembly.

Figure 12.

4.6.1 Re-Shimming the Backlash

NOTE : This step is only necessary when adjusting for

incorrect backlash.

c Reapply the spreader to the differential housing.

c Remove the bearing cap.

c Remove the differential.

c To increase the amount of backlash, reduce the shim thickness ‘D’.

(Fig.4.) and increase the shim thickness ‘E’ (Fig.11.) by the same

amount. Reverse this step to decrease the backlash.

c Remount the differential as before.

c Release spreader tension.

c Re-check backlash.
