Hello I’m looking for some input on my contact pattern. Currently backlash is about .008 and I still need to bring pinion preload up a bit but this is what I have. Do you think the pinion is too deep?
Looking for input on my Dana 44 gear swap pattern

The pinion is a touch too deep, but if you get the pinion pre load correct and the pattern still looks like that with the backlash in the middle of the range I wouldn’t press the inner pinion bearing back off just to change the depth with a pattern like in the pictures. I would button it up and start break in. I have done plenty of gears but am not an expert.
I agree, but I always have better luck getting the preload set 100% before dialing in the backlash completely.
Ok so I got the preload around 30inlbs and I took about .004 out from the pinion. I have two sets of patterns the first set with .005 backlash and the other with .008 backlash.
They are the Dana svt gears and I was going by the service manual it says .005-.008 for backlash and for new pinion bearings 20-40inlbs. So which pattern looks better? The first two pictures or the second.
I’ve always used the FSM specs when setting up gears in dana axles and have never had a problem.
As for your new pattern, I think your just a hair shallow, your coast side looks great but the drive side is a touch shallow. On a rear axle I’d rather have a good drive side and a eh coast side if you can’t quite get both perfect.
However, I would probably run what you ended up with.

I would not try running those SVL gears that tight. They are not manufactured to the same standard as Dana OEM gears. Try adding .002 shim and keep the backlash at .008-.010 and see what it looks like.
Ok I’ll give that a shot but it will probably be a couple days before I can get out and try it again. Thanks for everyone’s help so far I will post back with new results then.
Did you miss the part where he said his second pattern was .005” BL and the third pattern was .008”? I’ve set up a few dozens axles and always shoot for .008”.
it was .007 all the way around now I just need to press the new bearings on. Thanks for the help.
