Thoughts on the below pattern? This is for a Dana 30 HP with new Revolution Gears.
Pinion shim is 55 and backlash is 8.
Pinion shim is 55 and backlash is 8.
I’m just learning to do gears, so please don’t take my opinion as that of an expert, but it seems a bit shallow. The ghost pattern (1st one above the painted teeth on the drive side pic) shows this best, to me.
You are correct that it is the tiniest bit shallow but that pattern would certainly run fine.
Are you reading the curves at the inside and outside of the ring?
I was looking at the paint lines root and tip. Just trying to understand better. Have a bad case of covid right now so I'm pretty out of it

Thanks guys. I am going to try adding a few thousands and see what it does. I think I used too much paint which is making the lines seem flatter than they are. Going to clean it up and try it again.
Here's the final pattern i'm going to run (unless someone tells me otherwise!). I kept the pinion at 55 but had to shift the carrier by .04 to open the backlash from .05 to .07.
@Woodrow the hard line in my last pics was definitely too much paint and not enough resistance on the ring gear when spinning it.
Next up is drill and tap for the air fitting, button it all up, then start in on the rear.

Nice work. If its NPT, like the ARB I did recently, don't run the tap more than just through. It screws in tighter that way.
