MY ring and pinion shim setup

I do not have a pinion gauge to get the initial cone value needed for calculating the difference in stamped pinion cone length and measured. This calculation is used to adjust the shims behind the pinion race per the manual. I'm using the old case and a different used ring and pinion which requires a shim change. I have the shims from the purchased pinion that I can use as a starting point. I will have to buy a micrometer to get the thickness of those shims.

1) What is the old school technique to set up a ring and pinion without a pinion gauge?

2) Also there is two values etched in the end of the pinion one is 2.8## and the other is .295. The 2.8## stamp is the actual cone length. What does the .295 represent? is this the total shims needed? the manual does not say what it means.
 
Deere made a tool to set the pinion depth. It mounted in the carrier bearing bosses. Using the number stamped on the end of the pinion gear you would add or deduct
shims to get the correct depth of the pinion. Or if you have the original pinion you can compare the number stamped on that pinion and add or subtract shims based on
what the new numbers are. Without the tool JD had it's pretty much trial and error. I've been looking for the tool for a decade and haven't found one.

Once the pinion depth is set it's just a matter of setting preload and backlash for the carrier bearings. The Deere manual goes into great detail on all this.
 
Old school is Prussian Blue, a feeler guage, and possibly a dial indicator. Do a google/youtube search but don't limit it to a tractor. Very little actual difference in
your ring and pinion set up and one on any muscle car or truck.
 
I replaced the races and cleaned up the shafts. I tried to find the Prussian blue around town but the only place that had it was Napa and they were closed. I ended up using white grease as the marking compound and it worked for the initial check. Looks like I will need to add shims to the pinion... How much I'm not sure. The picture shows the markings as the inner curve has the mark on the heel and the outer curve has them on the toe.
