And finally .0325 PS .006-.007 BL. This one kicked my ass as well, 2.5hrs of dicking around with the shims.

What I have learned so far is, 2-cut gears read SOOO much better than 5-cut gears. But they are also MADDENINGLY finicky about carrier shim changes. The 2-cut gears move wayyyy faster with a smaller change, so that’s been frustrating to work with. Especially with the shim set I have.

So far, the .036 reads the best to me

Did 2 more setups today. I think .038 and .036 are the best to my eye

36 or 38 look pretty good, but I would take that with a grain of salt as I have not messed with 2 cut gears yet. I know they read a little different than 5 cut do.

38 looks to show the “bias” well

Ok, looking at that and also talking with a guy on the gear install FB page, .038 seems to be the ticket. It shows that nice diamond shape dead center of the tooth.

Admittedly, I'm a bit gun shy at this point to pick one lol

I contacted Revolution to see if they were willing to take a look at some patterns and give some insight. They called me within 15min, awesome customer service! They echoed everyone else, the .038 looked best to them. He said realistically, the .034, 0.36 and .038 all could be run without issue but they liked the .038 best. So I guess today/tomorrow I'm gonna button it up and pray :hidesbehindsofa:



I did throw the .038 back in last night with the same shim pack I had before. This time I racked the gears back and forth a bit harder before getting a reading and BL was at .005-.0055 all around. I also had to make up some more gear paint, I guess I mixed it a little different and the pattern looked different but the guy at Revolution still said they looked fine. At this point I'm just super gun shy and over thinking things but I can still kinda see the diamond pattern so I'm gonna run it I guess

So much BS to be had in this thread!

Glad it is finally seeming to come together for you.
Fixed it for ya lol

I'm heating the pinion bearing and freezing the pinion as we speak. I will report my findings probably tomorrow lol

you are may more patient than me. I would have probably "sent it" a WHILE back.
I've been >< that close to burning it down or knocking it off the lift a few times now lol. The only reason I haven't sent it to a shop at this point is mainly the cost. I'm already quite deep in and a shop's gonna want to start nearly from scratch so that's expensive. Plus I'm bound and determined to learn this skill cuz I know this won't be the last thing I wanna re-gear.

I think it has a lot to do with one’s attitude to the subject at hand, whatever it may be. Doing something because you want to, to learn a new skill, process, method, whatever, is quite a bit different than doing it because you only want or need the result at the end.

I put a lot of value on being able to do things myself, and learning how things work, come together, and come apart. Does it make sense to do that? Maybe, maybe not. Depends a lot on who you are and what you want from something.

Cost is certainly a big motivator for me, largely the reason I have what I have is because I do the work myself (except for mounting and balancing tires, real alignments, and state inspections). Basically sweat equity works well for me. Another big thing is quality control, if I do something myself, I can control the process, versus sending it out. With the general status of aftermarket and reman parts, being able to do “in house” work is more appealing than ever. While being a significantly lower cost, what is a reman Saginaw power steering pump these days? $50?, $100? Who knows what the reman actually had replaced, if anything. Seal kits are around $10.

On the used side, seems that as far as driveline parts, transmissions, transfer cases, differentials are classified as “good” if they spin, and that’s about it. Worked when pulled. I have little desire to pay a premium on something that could be a turd, I prefer to buy cheap as a core, go through it myself and know it’s got new seals and bearings, etc.

I don’t mean to wax poetic about all that, basically I commend you Zach for putting this effort in and persevering through the issues and challenges. I think a lot was learned in all of this, I know I learned stuff just being here on the sidelines. I think going through this now will pay dividends down the line if you continue to do differential work.

If you had just thrown the gear set in, ran two patterns, second one came out good and ran it, everything hunky dory, sure that would have been nice, but what would have been learned from that?

That's exactly how I look at most things. I knew this was a gamble going into it (though I NEVER expected it to take this long to work through) but it's something I've always wanted to learn. I also knew that if I could get it right, I could save a TON of money over paying someone to do it for me, especially considering there's 2 axles to do in this truck and I also want to regear the C10. And it will be done right, I'm not left guessing when I leave their shop. I am 100% the guy that will buy the tools and try something new over paying someone. Best case, I save some money, worst case I break even but now I have new tools and have learned a new skill. Knock on wood, I've never not been able to figure something out and have even more expense laid out having to throw in the towel and take it somewhere.

I appreciate you guys sticking with me about this, encouraging me and especially you @legopnuematic as well as others that have let me bounce ideas off of and get opinions from. I've felt pretty dumb half the time but considering I've done this 100% without any in person help, I have certainly learned alot. On one hand, I'm chomping at the bit to have this truck back on the road but on the other hand, the struggles have certainly taught me alot. Thankfully my C10 is just as reliable so I haven't been sweating this one being down too much. And also thankfully, even if something did happen to the C10, I also have access to our shop trucks in a pinch.

And I'm not done learning apparently lol. I did put the new pinion bearing on last night (the heat trick, not the press) and threw everything back on the truck and things moved on me a bit. I measured the new bearing and setup bearing and they were less than .001 different but the pinion ended up a good bit deeper. My BL tightened from .005-.0055 to .003-.004. So I made a carrier shim change and re-ran another pattern. I think maybe the pinion bearing didn't go all the way down. It looked like it did, but maybe not. So at lunch I'm gonna pull it all out and throw the pinion in the press to see if I can get it to move a touch more (with an old bearing inner to make sure I don't press on the cage of course).

Good news! That was the case, I got the pinion bearing to make one good "pop" and slip down solid on the pinion. Threw it all back in the truck real quick to check backlash and it opened up quite a bit. Just gotta make a small carrier shim change to get it back to where it needs to be but hopefully I'll run one more pattern and be right where I need to be :favorites37:
