3.1 Approximate Backlash Shimming
In order to reproduce a similar preload and ring and pinion backlash in
your Air Locker to that of your existing differential, measurements
need to be taken so that a shim thickness can be calculated.
c Secure the differential to a workbench.
c Remove the bolts that hold the ring gear in place.
c Using a plastic or copper hammer, tap in a circle around the ring
gear to separate it from the differential carrier.
c Remove the original bearings and shims from the differential center
using a bearing puller.
NOTE : Keep the bearings and shims separated so that they
can be identified as to which end of the differential
they came from.
c Examine the bearing cup and cone from Figure 3. for damage or
wear and, if necessary, discard it and replace it with the same size
and type of bearing.
