Pinion shaft diameter

[Roger]

As previous, the contact seems somewhat toe and low. Moving the pinion out should raise the pattern and as pattern generally moves in the direction of the pinion this should also move pattern more toward  centre of tooth.

If the diff is unmodified adj should fall into available range.
 
If you start looking at the pinion teeth it all gets more confusing! The inner dia of the cw is regarded as toe end of teeth.

A final check ideally should be made assembled. A .002 shim varies the pinion; with all the altered pressures the cw is likely  to move this amount on full assembly .

So one shim added should get me closer to a good result, will try tomorrow hopefully.
