Friction welding has been around for a while. The problem is finding a machine that will turn the two ends fast enough in opposite directions. Then you cram the two ends together till it glows bright red. Stop the machine and let cool. Instant weld with 100% penetration.

Its just more cost effective now to wire weld it. At least with the wire feed you can do it robotically and get the same result every time with a lot less fuss.

Well, good things are seldom easy.
I had just a few minutes to look at the # 64 blade on my 440ICD with the broken cylinder ram. The round pin in that one does not have a threaded hole in the top. I scratched across the top with a screw driver to see if it was just covered. The other pin has the threaded hole like it should.

This pin with no hole in the top appears to be wedged in there as would the correct one. I could not find where is may have been welded.
The pin does not even go all the way to the bottom of the ram arm.
There is no way to hammer it from the bottom. It will need to be pulled out or blown out with a rose bud which I am not in favor of doing.

What is a good way to get the pin out with no threaded hole in the center?
Should I try to drill and tap a hole in it? Is there another way to pull the pin?

Weld a 5/8" heavy nut to the top of it, then you will have the threads to pull it out, or spin it out, either way.

Those ram ends were welded on originally! .If you are going to weld it then it really should be kept cool and clear of splatter so as to not damage the chrome on the ram take your time keep it cool with water so not to burn the seals and cover the ram with a tin plate for catching splatter .Good luck We did it with an excavator main beam ram so it can be done !I bought a new ram for it last summer but it is working fine so the old Deere keeps working and the ram's can be repaired on machine like that .I just don't recommend it .Good Lock!!.Digitup.

Thank you Lavoy & Digitup!

If I can get the pin out with Lavoy's method, I may take it to the welding shop. They can do it right and keep it cool.

Digitup, mine and a few others are spun welded. But others posted pics that show the ram end held with a roll pin.
I guess it was one of the many ongoing changes that JD made.

Okay, I have kind of lost track here, but if you are working on a #64 blade, the angling cylinders have threaded on ends, not welded or pinned. Lots of them may have been welded, but they did not come that way from the factory. I have a couple NOS ends stashed away for my 64 if I ever get to work on it. Best way to fix is have a new rod made, and put it back togehter the way it was when new.
