I am removing the ball on the "J" arm to replace it, I don't have the ball yet and don't know which way the taper is on the ball.

I have been told to use a 10 ton press to push it out - so which way does it come out I presuming i push on the ball to take it out. ("to put back in" the ball goes through the arm and pushed from the flat end)

when replacing the ball do you just press it back in, I have been told to weld it as well.

Can't see why you would have to do this if it's pressed in the first place but what do you guys reakon.

Thanks
Rhino

You have to grind of the mushroomed end opposite the ball. And push it out from that end. Some times they come right out, the last one I did it took everything my 20 ton press had to get it out. The hole on the mushroomed end is counter sunk a bit and it is best to take a die grinder with a pointed burr and grind it out. The shaft on the ball has a very slight taper on it, press it back in from the opposite side and “Rosette” weld it over lapping on to the arm and then also weld it on the opposite side on the shoulder. Pre-heat the arm before welding it and let it cool completely on it’s own to room temperature. <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

OOPS is right about the mushrooming effect for sure....it's not enough to just grind off the raised lip....have to run a counter bore down at least .125". Been there. ZUK
