3.1
Measurement of Pre-Load Shimming
In order to reproduce a similar pre-load and ring and pinion backlash
in your
Air Locker
to that of your original differential, measurements
need to be taken so that a shim thickness can be calculated.
Secure the differential to a work bench.
Remove the bolts that hold the ring gear in
place.
Using a plastic or copper hammer, tap in a
circle around the ring gear to separate it
from the differential carrier.
Remove the original bearings from the
differential center using a bearing puller
(Fig. 4.).
NOTE :
Keep the bearings and shims
separated so that they can be
identified as to which end of the
differential they came from.
Examine the bearing cups and cones from Fig. 5. for damage or wear
and, if necessary, discard them and replace with the same size and
type of bearings.
