Topic: J-arm ball flip question

[trekker]

I want to flip my ball on my j-arm and need to know which side is welded because i dont see a weld on either side.WE heated it up and  was using a 20 ton press with know luck. So any help would be great

dont think they are welded just pressed in, there is a thread somewhere in here where they were talking about how to do this in detail.

they are pressed in  and bradded  like a rivet,   on the top  of the arm is the mushroomed part of the "rivet"  it must be ground off smooth till you can trace the line around the stem  press only on that part  then flip and weld the back side

[Rockdiver]

Once you grind it down  if you heat the outer edge where you ground  it down you willsee where it is bradded and will make it easier to press out

cool thanks for the advice,I searched for the answer but didnt find the answer i was looking for

i have one i ground down, but never got around to heating it and pressing it out,  maybe later this month it will cool off  and i can stand the heat

i answered your question on my thread.

top side is heated up and pressed, and it is a reverse taper, so it gets bigger on the side that is shroomed, no weld. what I do is grind it flat, find the circle in the metals, use a deburing tool and follow the circle, kinda deep, then press out the ball. press it back into the other side, and weld around the base of the ball, and plug weld the other end. you want to weld both sides, because they might pull out without that.

After grinding the swedged material of the pressed in ball flush with the arm, I hammer on the side of the arm untill you can see the parting line between the insert and the arm.
Next I drill about ten 1/8" holes around the inside of the parting line about 1/4" deep.
Put it in the press, and it should pop right out.

I have never been able to press the ball out without drilling around it first.
However, I only have a 40 ton press.
