The best of my research into straight cut bevel gears is that there are only two adjustments. Pinion depth, and backlash. (ring gear depth in the pinion)
In all my gear work, I have never seen straight bevel gears with more than about .006" backlash when new.
The machining of the differential housing by IH when it was manufactured pretty much guarantees the planar relationship between the two axis of rotation (ring gear and pinion)
If it were mine I would set it up to have about .008" backlash and run it. It will make some noise, but it will probably wear in and be less distracting.
The only thing that can make the issue be weak and easily damaged is to have the pinion shaft (trans output shaft) either bent, or out of alignment. The intermediate (pilot bearing between shafts, and the front trans bearing all play in the same orchestra toward that alignment.
If those are good, set it and run it. Jim

 Re: One more differential question in reply to Janicholson, 02-20-2013 18:07:28  
I did check on the runout (if that is the correct word) of the gear end of the shaft as best I could when I had it open and it seemed straight but without a proper magnetic base for the dial indicator it was hard to get it down in there. Thank you for all of the advice, I am hoping that what you said will come true about it getting quieter over time, and if not I can always try the other set.
