Dana 60 knuckle rotation

Ok, I know this has been covered. I've searched but can't find the threads. With the new motor tcase combo in the rock troll I have some serious front drive line issues. So I need to rotate the pinion angle up. I want to retain the full width so I don't want to cut the axle tubes off. Any ideas? Grind off the welds on the c's?
I know others have to have run into this problem. How did you solve it? I worked my ass off the last six weeks to get this ready for ejs. I was soooo close.:-\

Basically grind the welds off, beat the Cs to the rotation you want, then weld. You can weld inside the Cs too for added strength.

No wonder I couldn't find it. When I searched all it said when I tried to go to it was can't be found or some such bs. So grind off the welds and I should be able to pound em to a different angle? I really don't want to cut the tubes if possible. Damn, James wish you wouldn't have deleted your thread.
I already read the one you posted the link to Greg. Thanks for trying to help me get the info to have the guts to hack my 60 apart.:eek:

Thanks for the pics James. I was thinking about metal cut offs in my worm drive. Figured I'd have more control than a hand held grinder.

i use 1/4'' air-arc rods, but the grinder or sawzall works to. i prick punch the origanal location ( center on the tube ), make a few marks on the tube and the knuckle then cut them off and grind them clean. slide them back on and using your marks you made rotate the knuckles till the match the same distance apart from each side.
tack them, install the axle and make sure there where you want them. i then take the axle back out and stand it up on end and weld them flat. i used to do them with 1/8'' 7018, but when i got my MM250 i weld them with .035 set on spray ( well more like a globuler ). i do one root and two cover pass's all of them around 1/4 to 5/16 big, so when i am done i have a 3/8 weld or a little bigger, never had one fall off or break, jason.

No problems huh? I was thinking about running the root with my MIG, then goign back with the 7018 and burn it in real good (what I do on my 8.8's when I weld the tubes to the center). ...Now maybe I'll just do the two passes like you did?

What did you do James? Did you even get that fancy? ...I'm trying to remember your thread where you narrowed that axle 5.5"....(why did it get deleted?)

Did you buy a bigger wire welder? If you are thinking about using your 110 volt MIG to weld your tubes to the knuckles stop do not do it. Even with a 250 size machine short arc is really not a correct process for the thickness of the pieces involved (Duel shield or solid wire spray is what you need). The root is what is important not the cover. If you have a DC arc welder that can run at least a 1/8 (5/32 would be better) 7018 rod use that.

boghog nailed it agin, i set my machine ( MM250 ) at 320 ipm's and 26 volts with 75/25 ( steel mix ) and runing .035 hard wire i run a globular root and two cover's, one down two over. i also have a ranger 250 generator that i can can run 1/8'' or 5/32'' 7018. i even did some dana 44 knuckles with jet-rod, i was all out of 7018 and since i always weld them flat ( axle standing up ) it was very easy and nice looking.
i always back step the weld so i wont leave cold starts and stops and i stagger the cover welds agin not leaving any cold starts and stops. is this over kill, kinda but i been welding for like this for 13 years and you cant break habbits that you do day in and day out, jason.

I have an old M35 (with a Tweako gun) that I've had for a while. I bought the little 135A machine for little stuff 3? years ago. The M35 is just too big and heavy to drag around for most things. I just bought a MM251 to "replace" the 35 - haven't even plugged it in yet....

Now the next question, what kind of dual shield wire should I run then? Thoughts about Lincoln E71-e or m??

What is better, spray arc or dual shield? And what gas should I run with either? Wire? Currently I have 75/25 and 35 wire.

I currently don't have the ability to use stick, should I wait or do you think I can spray arc or dual shield the knuckle back on safely? It almost apears my best bet would be dual shield, as I don't think I have enough machine for spray arc? I guess I'm asking if you only had your 250 class machine, how would you weld the knuckle back on, or would you not even attempt it until you had access to use 7018 stick.

Maybe 420 answered this with "i set my machine ( MM250 ) at 320 ipm's and 26 volts with 75/25 ( steel mix ) and runing .035 hard wire i run a globular root and two cover's, one down two over"

if you have the .035 hard wire then run it, the duel shield core wire aint cheap but its very handy to have around. just fool around with your 251 with the way it is now with some 1/2'' plate and you be able to get a good feal where you would want it for the C's. dont pay atttintion to the parametors on the inside of the machine, just find a good setting and weld them, trust me they aint coming off, jason.

I talked to my dad in CA today, he can burn the 7018 in for me - but I would have to pack up everything onto a trailer and haul it all down to him. My other choice would be to set it all up and pay a local shop to do it. Or, do it myself with the 251.

If I end up doing it myself, should I still run a root with two covers? I was originaly only thinking about the root and one cover - before this thread came up and got me all scared that is!

Just checking. I know how you said you did it...

So I have to ask, what benefit does the root and two covers provide and do you make all three passes one after the other, or do you let it cool between?? And if your not letting it cool between passes, won't that shrink the axle tube? I'm not near the welder you and bobdog are, so forgive the rookie question. I just want to understand it best to keep from mucking it up.

What I was thinking in the beginning was a pass next to, but not touching the knuckle - making a V, kinda (root pass right?). Then take and make another pass to fill in that V - laying the bead on the knuckle, in the valley and on the root (cover pass right?). Now if you do two covers would one be in the V and the other over the root? Or are you laying the first cover in the V and then the second over the first cover, touching the knuckle and the root?

If you are considering packing up your axle and taking it somewhere to be welded, then why did you just buy a new mm250? You are acting like you have never welded anything before.
