I have beat on these C's and they are not budging. I went back and re read this and you said it would take two hours? Do you think it would help if I heated them?

Without being there I do not know how well you cut the welds. I had to cut pretty deep into the tubes and then grind into the inner C. The manufacturer used a lot of heat and penetrated the metal pretty good. If they don't move and you haven't seen the hairline crack start then you need to get back to grinding more. It only took me two hours but I have been an industrial mechanic and builder for over twenty years so I have developed a pretty good knack for getting things apart. I am not knocking your abilities by any means but don't take my thread as gospel. It is simply a write up on how I managed to get the job done.

I wouldn't worry about cutting the tubes a bit or taking some metal off the inner C because you will be adding metal back when you weld it back on. I ran my welder very hot and made three overlapping passes. I can tell it penetrated nicely.

No problems I'm a welder and I'm sure all surface welds are gone. I can't grind the penatration. I was thinking about hooking the diff up between two vehicles and applying tension with my winch then try beating on them. I don't think I have beat on them enough. Also I read somewhere that they may be pressed on.

 

[Kane]

They are a press fit, not a slip fit. Take a pic of the inner C if you can so we can get a good look. Maybe something will pop in my head if i see it. Good luck man.

. Also I read somewhere that they may be pressed on.

I believe the industry standard is .005 press. As you probable know that's darn tight.

 

[rr41mag]

Yea C130 wheel races were press fit too. When one of them popped out the whole shop knew it. We would freeze the races and warm the wheels and they dropped in. .005 is ALOT for a press fit.

 

[CJ]

Probably .0005 - 1/2 thouh can be tight but doable.

 

[Kane]

.005 seems too tight if you consider the locking sleeve on the rear axle shaft is .004.

Ok guys I know what your saying 5 thou. sounds like way to much to me to, but I just got done boring a set of C's made by Solid Axle for a D60 and they wanted a 5 thou. press. Don't shoot the messenger. could be the factory used less...I don't know for sure.

 

[Kane]

One. Those are awesome!!
Two. I am just a wannabe so I am hardly a genius when it comes to press fits specs. If that's the spec then that's the spec. It explains why it took the amount of work it did to make them move.
