Well, since I'm out of shims, I thought I might as well get a few other opinions on this pattern. This is my first time setting up gears, so any advice is appreciated.

Backlash is pretty tight! 3-5 thousandths. Carrier bearing preload still needs to be set/increased (I ran out of those shims too

)

Thanks!
Billy

EDIT: Resized. Sry.

That edge looks pretty sharp to me toward the root, but I can't find any advice on what to do about that (except maybe to try to bring it in toward the root some more.)
Thanks,
Billy

Looks good the pinion looks a bit deep though I might suggest to take 2 thousandths out of the pinion and re-run the pattern... otherwise it looks great...

Deep? Really? I thought it looked shallow if anything. Which is why I was so concerned about the backlash.
Thanks!

I tend to say it's a little deep too. The top of your pattern is curved and the bottom is a sharp flat line. Bringing the pinion out just a tad will even the pattern up and help bring it back to the center of the gear both in depth and in relation to the gear center line.

OK, I tried removing some pinion depth shims, but the pattern got a bit too close to the top for my liking and the straight line toward the root was still very distinct. So... I tried going back the other way... with more pinion depth, but I can't get rid of that darn straight line.

Any ideas?

Thanks!
Billy

What kind of axle is this? Front or rear? Hi pinion, low pinion? That would help to determine which side is the drive and which side is the coast, since you didn't label your pictures.

In his last post the first was coast the second was drive. Look at your backlash. You said .004 before, way too tight. Shoot for .008. Pm with email- have some info that might help.

How much p depth did you take out? Might still not have been enough

Sorry, it's a rear, low pinion Dana 60.

Backlash is at 8 thousandths now. I'll try reducing the pinion depth again (more) and see how it looks.

Thanks,
Billy
