Yea well when I was first told to try a new fitting I laughed to myself since it would take grease when not in the backhoe.
I literally only changed it to a new one and it worked easily. Also swapping one from a different place on the tractor didn't help.
I tried everything else before, lifting rotating, pushing down and nothing else worked.
There is another thread somewhere and the same solution solved their problem too.
Don't forget, I can grease both pins while swinging side to side; it's not the fittings. Read the thread in Skyco's link. Quoting him, "The pin is so dang tight I had to use around 5000 lbs of force with a mini ram to push it out*." This is just a tight fit. I can fix this.
