I'm looking for some opinions on the gear pattern for my HP Dana 30. Currently it is set up with a pinion depth of .045. Backlash is between .07 - .08 when checked on 6 different points. I feel like I'm getting close but would appreciate any opinions.

I have been chasing the coast side for a couple of patterns. I'm going to add .0035 and run it again.
 
Increased the depth of the pinion a couple times and now have it shimed with .05. I adjusted the backlash and am sitting between .07 - .08. Thoughts?

I thought your first set of pics was where it needed to be. Looked good. You can tell by the teeth that don't have paint on them....the line at topland. A pic of the pinion might help. Your last pics are too deep as shown by the harsh line at the root.

Don't forget that you'll favor the drive side of the ring gear for a HP30.

Do you have any other slingers or a baffle in there? .045 seems thin to me. I usually start mine at 57 thou (ish).

That's one of the concerns I was grappling with. With the deeper pinion depths I kept getting a solid line towards the root.

I do have a .031 slinger installed and I should have included that in my shim measurements. I've just been discounting it on my own worksheet since it is permanent and couldn't be changed. This is how the pinion appears currently with the .081 of total shim. I'll return to my earlier set up and compare the pinion gear.

I returned the set up to my 1st posted pattern. Total pinion shims of .076 and BL within .07 - .08
