Pinion depth way off

I put the oem .037 shim in and checked the pattern and this is what I got

Looks like a decent pattern to me, right on the center of the tooth with feathered edges and no sharp lines... If I were to be super critical it may be slightly deep but hard to judge by a photograph.

Question, was the ring gear put under tension while you did the pattern?

I recommend you check pattern in three spots to ensure the ring gear is true and square on the carrier

If Backlash and TTR are good I would probably run it.

You are in the ball park, a little shallow. What is the backlash at?

I agree with @CalSgt , check three places backlash/pattern and for runout. It’s a good practice and should reveal any discrepancies.

Still in setup bearings? I’d probably try about .003 more pinion shim, about .040, depending on what shims you have.

Pinion was under tension, i torqued everything down before i ran it and backlash was .06” when i checked it multiple spots and times. The extra did wear off on two other spots on the ring gear if that would be helpful to you guys, or are you suggesting to re apply in a different spot and run again?

Backlash is consistently .006” and yes still using setup bearings with all original shims that came off in the first place

I was suggesting to apply and check pattern in 3 spots… We don’t need to see the other patterns, it’s just for you to ensure that the gear contact remains the same.

If you get a noticeably different pattern it’s indicative of a problem like a piece of garbage, bulge around one of the threaded holes or dent/ding interfering with the fit between the ring and carrier.

Just cheap insurance is all.

I don’t have the spec handy but is a good idea to check the pinion and total TTR but not until you have your new bearings installed.

Okay I will definitely do that, appreciate the help
