Narrowing a 9"

[bigjhoov]

What size tube are those made for? The ones I used were for 3" OD tubes. The tube on my new housing is 3-1/4".

Seems as though they are for 3" axle tubes with an i.d. of 2.62". After looking further I noticed that there are both slip in as well as butt weld available. I guess I'm just used to the slip in style in the aftermarket housings. Sorry for any confusion.

I really wanted to turn these down to fit inside, but I had lots of folks tell me to butt weld them... and I'm not sure I could've gotten the near perfect alignment if they had slipped inside. The angles might have never lined up ???

But these things are burnt in deep. I was proud of my little 175 Lincoln. Especially when I realized I had my .024 wire in it and a .035 tip! Once corrected, it was very nice.

Good point. But I'm in an auto so I don't deal with it... yet. But I AM going to 5.13 gears....

I had mine turned down to fit inside. Came out spot on......

Might try it on the next one. The second reason I bought the fixture was to do more housings, and maybe sell a few.?? And I'm thinking that because of the reduction in tube diameter at the end of these particular housings, it may be possible to reuse the original ends by turning them down to the proper size to slip into the tube after it's cut off.

Oh I think you should use the fixture no matter how you do the ends. It's the only way to get things right IMO.

That said, I didn't have a fixture so I used the 3rd member and the axles to align everything. Welding trashed the old bearings but I was changing them anyway. My housing came out really nice. No more leaks from the ends being damaged.

I've since went to 31 spline axles and set 20 bearings with no issues.

nice and when you put the gear and bearings on do it like this;D

yep and easer to put shims in between the carrier and ring gear, than messing with under the bearing crap

Nice Adam...

Well, at 10pm I pulled out the driveway to go to the car wash. Today I pulled the third member I'm starting with and got it disassembled. Man, I didn't know gear oil could cake up like that. So after dealing many other distractions today, i decided late at night would be the best (coolest) time to go to the car wash to clean the case up. Afterward there was nothing left to do but....

Get ice cream.

But it turns out they close up at, like, dawn every evening (that's pretty early if you ask me...). So off to the next best...

If you now wondering where the action shots from the car wash are, I'll remind you that the kids went to see their grandmother at the zoo, so I'm by myself. And I pretty much needed scuba gear so I certainly wasn't getting my phone out with water spraying everywhere.

Maybe some more pics later tonight.

Its going down....

Yes, on the kitchen table. BUT! There one inch thick styrofoam under the old Spider-Man bed sheet. (I guess there are so many new spider man movies that this sheet is obsolete??? I found it in the shop floor.)

And I thought I'd share something else I ran across today.

Got it way cheap!

Now! To figure out how to build a chunk... Hey, Ian!!!! (Who knows maybe that crazy Canadian off-roader from TV will see this?)

I'm probably gonna call it a night now. It's 11:30 pm and I was up at 4am thinking about a 98 year old ww2 navy vet that had three ships shot out from under him. He was taken to the ER this week with congestive heart failure. I spent an hour visiting with him this morning and he looked a lot better than I was told. So...

Until next time.

Here's a few more gadgets I got for this project...

Did I weld this one at the right angle???

I decided to go with Barnes4wd u bolt eliminator kit because it was cheaper than having a heavy u bolt set and hd plates shipped to me. Plus, this allows me to source hardware locally, rather than ordering longer U bolts if I want to put blocks under it later.

This morning, we're pressed for time....

And after that I slowed down for the lunch of champions.

There's a lot going on in that pic...

I guess it's time to open myself to the real criticism. I've fought with this thing. The crush bearing ended up requiring a 12 ton press... then the outer bearing wouldn't hold the preload because I cleaned up the black finish so the bearing press on a little easier... so after putting it together, I tightened the nut until it took about 25 in lbs to rotate the pinion housing. That's what the instruction called for with new bearings.

So then I pull out the fancy pro form (cheap) pinion depth setter to set the pinion depth (is that statement too redundant? I heard you need some redundancy for long, high risk missions.)

the pinion and gear were marked 2909 for pinion depth? Does anyone have any idea what that refers to? The 9" gear jobs I read about talk about a PD around 1"+/-. I did some lookin around and found reasons to decide maybe it meant 1.029 with .009 backlash. Whatever...

I played with gear pattern until I came up with these pics. Here's the drive side. Same in two different places.

Coast side.

So now I guess it's time to slap in in the housing and put some shafts in it.

And I'll probably leave the table for the wife to clean up...

Looks great to me I'd run that.

May I ask why crush sleeve over solid shims? Crush sleeve is the most common failure I repair. In our application they don't like side loading from using the yolk as s skid plate or getting bound up in reverse, you can create enough load to crush it. Nothing wrong with it just not not something I would ship a customer, I'd feel like I needed to warratee it.
