Ring & Pinion pattern. I'm stumped. Measured it.

Don't we love setting up Dana spicer rear ends, especially the Dana 60 Do you have a set of set up bearings? If not get some I remember paying Bob Lambeck $75.00 to set the gears up in my Dana for the four speed Hemi Cuda, best money ever spent I charge $150.00 now and it still takes 8 hrs+ to do one usually

Man am I glad I have a 9"..

Looks like too much work..

Keep at it, you're getting close..

But when I have to work on my 70 Cuda its a different story, have a Dana

Looks like you're goin crazy and this is just my opinion.

I'd go back to # 21 set the BL at .10 and run it .

What brand gear is that ??

DUDE you are definately doin it tuff.....I see you havent mentioned weather or not you are loading the gear set when setting the pattern?? I cant see any marks on the spool or ring from a lever or like?
Cuple tips, always clean the paint/paste off the both ring & pinion each time you make a shim or BL change, dont apply to much paste (which you have there)it makes for difficult reading, the extra paste tends to wipe over the tooth & disturbs the pattern.

I was thinking that quite awhile back that $50 to $100 spent with a reputable mechanic would have been well spent.

What, and miss all this fun? ...but seriously, I have the tools to do it, and it's only this bad the first time. Lesons learned this time will make the next sets easier and faster. Gotta learn somehow, right? No better way than by doing.

Looks good to me...them numbers= 1 set is matching number for the the ring gear you will find a set just like it on the ring gear. 2 is pinion depth.

here is a pic hope it works

your pattern looks nothing like mine after we finished it last weekend. I wouldn't be happy with it. from what little bit I know about setting them up it needs some more tweaking.

---

Something doesn't quite look right.Who's gear set?New or used?

I tell you this. it is way to hard to tell.one thing it is feel thing about how much pressure you use to get that ..pattern. I use a 3ft bar to loan /put pressure to get the pattern.. you can not loan it like it would be in the car. so how do you ask someone how much pressure did you use to get that pattern?..I going to asume he doing this by hand with light pressure. he is not far off. I see them be dead on and the rear end make noise. I see where you think they would make noise and don't..I do this for a living I build at lease one a week..

Jamie,the drive side isn't to bad,but the coast side pattern is not consistent from tooth to tooth and the angle or pitch seems off.I wander if the ring gear is seated on the carrier flange flush or the races seat squarely in all the bores.We like to see a consistent contact patch either in the middle of the tooth or to the lower 2/3 and similar on the drive and coast.Maybe Doctor Diff will chime in.

Is the rotation free or is there more drag in some areas,like the ring is moving in and out of the pinion or back and forth?

Not telling you what to do,just some more advise. Take it to a reputable mechanic with experience and have him recheck everything.What do you have to lose after all the time you spent,and minimize your risk of ruining a good set of gears. He might find the problem and you will be more knowledgable for your next set.

---

I wouldn't run it like that. that thing will knife edge the gears before long. I would send them back to strange if I were confident it wasn't something else before running them. send them the pics and see what they tell you.

If you don't know the correct pinion depth it can be calculted by measuring the thickness of the pinion head and subtracting it from the mounting distance for a Dana 60(3.125").The difference will be the depth that the pinion should be installed.If your pinion is marked +- a number,add or subtract it in thousands to your pinion depth.

It took me two-half days. I had to walk away from it on the first day I was so frustrated.

The best pattern that I achieved was made getting the pinion depth right-on to what the manufacturer recommended. The problem is the depth changed when preload was applied to the pinion, so it was a lot of trial and error.

Check to make sure the cap is cut on the c/l.
DO NOT assume that it is cut perfectly when measuring to the top of the pinion.

The bottom line is always the pattern. Even if you put it in with a tool it still gets tweaked by looking at the pattern. I don't know why your coast is looking like it does but i am not there. you have been all over with the pinion shim and this is the best you have gotten. If you are sure this is the best you can get and all the preloads are right run it.
