3 Approximate Backlash Shimming

3.1

Bench Measurement

In order to reproduce a similar pre-load 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.

 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.

NOTE : Keep all shims and bearings separated so that they

can be identified as to which end of the differential

they came from.

 Examine the bearing cup and cone from Figure 5. for damage or

wear and, if necessary, discard it and replace it with the same size

and type of bearing.
