New holland 650 twine arm adjustments

Okay I replaced the end of the twine arm because the ring had broke where the string goes through the end. After reinstalling the new arm somehow j guess the arms are out of adjustment. I have the belt off turning the wrapper drive by hand and the left arm is rubbing just under that bottom roller to the point it hangs up causing me to have to take the one bolt that holds that arm in and hammer the arm into the tube then the whole arm springs back to where it should be. When it gets to home position it stops to soon and not where it used to stop. Is there an adjustment for this? Thanks
