Have you seen what that stuff will do to kittens?

(sorry, couldn't resist)

Cautionary note on the freeze spray - the stuff is cold, but there's not much mass to transfer the heat from the races/pinion/etc to. It may take A LOT of spray. I tried something similar once, and I just couldn't get the temperature down very far. Hope it works, it's a helluva lot more convenient than waiting on the freezer.

Well the canned air/duster stuff worked great. I sprayed the race until frost formed on it and dropped it in. While it didn't just fall in, it did go in much, much easier. So I would say it was a success.

Hmm, I didn't realize that diff vendors have different way to locate the shims on the pinion deal. That sucks.

The one downside to using a "setup" bearing is that your pattern may not be accurate for the "real" bearing. The setup bearing may allow the pinion depth to be deeper than a fresh pinion bearing but I'm no expert at this.

My 80 has no factory lockers so when I did the R&P swap, I didn't have to go through this ordeal as Jack. It sounds like an utter PITA from hell. I can understand your frustration of time and money expenditure.

I didn't either until now.

I used the "setup" bearing to get everything close and pulled it off and started to put the real bearing on. You know the one that R and P biz said was the right one. Well I bent the support frame on the press, spent a good portion of last night fixing that. So we put the pinion in the freezer last night hoping that will make a difference. We'll see. If I can't get it on after freezing the pinion and lubing the bearing, then I am going to try a different bearing.

Part of the problem we have been having is even with all of the internet/FSM type information, there are some things that neither really tell you. So some of it has been a learning experience. We worked very hard getting the backlash in spec, only to realize that we were going down the wrong road. You just have to get the BL in the "ballpark" and then do a pattern check. Adjust the pinion to get the pattern where you want it and THEN adjust the BL for real. It's kind of a see-saw effect and finding the balance has been our trouble. We were set to go for the final setup when the press problems started, so once again, back at it tonight.

Could you use Dry Ice for the flash freeze?

Might be an option.

I should be able to pick that up...well anywhere, right?

So far, my canned air is working, so I am going to stick with it.

The Saga continues.

P.S.: I couldn't imagine doing this on a Dana style rearend, under the vehicle.

Cool. Glad I was wrong. How much did it take?

 

[450 DUDE]

AHH Im just talking $hi@ , It would have to be pretty extreme for that action.


But you really can get that just a bout anywhere , well any welding store.

Good to hear you are making progress even if it is slow.

Freeze spray is the same thing as canned air, it just has a pick-up tube so you can hold it upright.


So can we assume R&P biz isn't getting a glowing endorsement?

 

[chicago]

Wow, I kind of knew that ths was an involved process, but never realized how involved.
Do you think that it is just the R&P stuff, or is it just the entire set up?
They make it look so easy on Extreme 4X4....
SO to get this straight...youre using the old bearing and races for set up and pattern check, and then you have to go back and re assemble with the "for real" components, right?
Is the reason for that so you remove the warn parts easier if something is wrong in the fittment?

Where are the DAMN PICS for CHRISSAKES!

SOunds as if youre learning quite a bit on this topic as youre going along!

BTW, what press are you using?

The idea is to grind off material from the inner part of the old bearing so it will slip fit. You use that to set the shim so you don't have to press the real bearings on and off while you go through the trial and error part.

Part of the drama was the missing/wrong/different than expected parts. I can see where if you had your ducks in a row it would be an afternoon job.

It's all good, I didn't realize that it was that easy to get.

I agree, and even though the frustration has gotten a little high, I am still learning and doing everything right as far as I can tell.

I kind of thought so.

Definitely not glowing.

It is easy, when you know what you are doing, I don't, so I am figuring it out by trial and error. The good thing is that I am learning and I will be able to say I did it.

I haven't taken too many, pictures, kind of been on the back burner, but I will get some posted.

If you never try you never learn. If we never go into the deep water we never learn to swim.

Good on you for jumping into the deep end of the pool.

Yeah, this has been like ocean trench deep.

The good news, we finally got the rear gears set up.

Figured out the secret to the pinion bearing...Pinion in freezer over night, bearing in oven, heated to 400 degrees. Set the pinion on the counter next to the oven, pull the bearing out of the oven, drop bearing on pinion and like freaking magic, it dropped all the way into place, no fuss, no muss. I wish I would have had the camera going for that one.

I just have to finish putting the e-locker mechanism back together and it will be done.

I don't even want to think about the front right now.

I am so relieved to finally have the rear done. I will get some pictures up this weekend.

Congrats Jack!
Glad to hear that it went together easily with the technique!
The front should go together much easier now, yeah?

Nice job dude!

 

[locrwln1]

Ok, I finally got a chance to get the pictures done. Sorry, I didn't do anything yesterday (Sunday), I got called out for work at 12:00am and didn't get home until 10:00 am, so I pretty much was worthless yesterday. Anyway here are the pics.

 

[locrwln1]

Diffs are out and on the ground.

 

[locrwln1]

Some more.

 

[locrwln1]

The second pic is of the first gear pattern check, it's wrong. The third pic is of the press after we broke it.

 

[locrwln1]

The first pic is of one of the other gear pattern check, still wrong. The last two are of the final and good pattern (both drive and coast sides) setup. Ready to be buttoned up.
