On My 3pt I went to raise the 3 pt arms and noticed that the Hydrolic pump was not shutting off when the arms reached the top. I had to push the lever back down some to get the pump to stop. I went to look at the Control arm to see the adjustment had come loose and found the control arm was actually bent and cracked at the base. I ordered a new arm and assoc. parts. But first I can not firgue out how to get the roll pin out. Where is it located I am not sure I can get a Drift punch in there. But more importantly. I am concerned that if I put a new arm on that it may do the same if something else is wrong. How hard should it be to manually move the Control arm? When disconnected from the arms, should I be able to move it by hand? I can get it to moce some with a pipe wrench on ( Just wanted to make sure it was not Seized up) and it does move some, but it is pretty stiff. Is that normal?
