Need to make correction to read as---------- (B)bottom of the crown wheel
carrier BEARING BOSS.

Also---------It has always been my understanding that the first pinion ever
installed
along with the original bearings+ an approximate .002" amount of bearing
wear, is the mirror of the Dummy Pinion dimension.---------- Well that is if
the the night before the guy building the first one didn't have to many
Speckled Hen Beers. But then it probably wouldn't have lasted this long.

wear, is the mirror of the Dummy Pinion dimension.
In other words with the original pinion installed, the dimension between the
(A)Pinion head face and the (B)bottom of the crown wheel carrier should
remain the same for the new Pinion depth setting except for differences
recorded(stamped) by the manufacturer on the Pinion face + or - .xxx". The
gear set that I currently have has stamped as a checking distance of .004"
which I interpret as adding .004" to my determined A to B dimension if it
had a -.004 I would interpret that as decreasing the A to B dimension by
adding that much more shim to my Pinion Shim. Of course always verify the
final assy. by the meshing pattern.

Hope that others will chime in for any additions to Ideas,techniques or
corrections.

      I'm heavily into the differential rebuild for the winter. My focus is
getting the
correct pinion gear depth. The official Bentley manual, page 346  mentions
the dummy pinion
Churchill Tool M84B-1, which I assume is the factory standard for getting
the pinion gear
depth close enough for the proper pinion/ring contact tooth pattern. Does
anyone know what
dimensions this dummy pinion has? Obviously, the shim you choose to put
under the inner or
head pinion bearing is what this tool can measure. Otherwise its trial and
error and going
by contact patterns.
                               Thank-you
