Dana 44 what have I got myself into pattern check

[Bradsta]

Dana 44 with arb 4.10 Proactive gears. As far as I can tell they come from the same place as revolution.
Pinion has .058 was .055 when I took it apart but its as close as I could get with the shims they gave me in the kit.
Backlash is .007

You're deep. Try removing 7-10 thou, reset backlash and re-run a pattern.

Does the side of the ring gear have a circle K stamped in it?

Great thanks. I can get to .049 with the shims I have.

Yes they have that stamped on the ring gear.

I went with 51 thou on the pinion and .009 backlash.
thanks again

That is very close! You might be 1 or 2 thou shallow is all. See if you can make a shim stack to reduce it by that much. That is runnable I think, but I'd rather have it 1 or 2 thou deep than shallow. Looking at it closer, that might be it. But still try to make it 1 or 2 deeper if you can just to verify.

That's the closest I'm getting with the shims I have on hand. Great to know I'm getting close. I need to get a new pinion race and seal housing so ill see if I can get some shims from the bearing place on Monday. If not I fly out to work for 2 weeks so ill see if I can order some shims while I'm away then have another crack when I get home.
Thanks again and thanks for the videos they are what has given me the confidence to even attempt this.

Looking at the drive side, I think you are there. If you have have the patience, it would be worth verifying though. Glad the videos gave you the courage!

Do me a favor and run the pattern in a different location (make a reference mark). Use only enough compound to turn it yellow. I don't want to see the build up of compound at the root like on your current drive side pattern. Then take a pic at a slightly steeper angle (not so much where it looks like you are looking directly at the top of the tooth...go more perpendicular to the tooth)

Do you a favor sure thing. I want to know how I can buy you a beer to say thanks.
I ran it 4 more times. still looks like its getting that build up but do these look any better.

You're there. I wouldn't change it.

 

[hosejockey61]

That last set of pics is the perfect angle. Well done.

 

[Bradsta]

Awesome. I will order the new seal housing and button it all up.
My savvy short arms will get here Monday. Just need ARB to get the housing for the front Dana 30 to suit the gears.

Elaborate please

Elaborate please

That is the mark of a particular manufacturer in Korea.

Is that a good thing

Is that a good thing

Yes - it’s the same gear plant that makes Revolution’s gear sets
